Evaluation of Antimicrobial Efficacy of Silver Nanoparticles

Synthesized from Punica gratum Extracts

N.A. Tambe*, P.M. Tumane Department of Microbiology, L.I.T. Campus, R.T.M.N. University, Amravati Road, Nagpur, India

Abstract

Nanotechnology is a branch of science which has open many routes of technologies. With the

rapid development of nanotechnology, application has been extended further and now silver

is the engineered nanomaterial most commonly used in consumer products. Green

nanotechnology is an area with significant focus at present on the important objective of

facilitating the manufacture of nanotechnology-based products that are eco-friendly and

safer for all beings, with sustainable commercial viability. In the present study, we have used

a green route for the synthesis of silver nanoparticles by using plant extracts of Punica

gratum. These eco-friendly Ag-NPs were characterized by UV–Vis spectrophotometery which

exhibited maximum absorbance in specific nanometre range in UV–Vis spectroscopy.

Further characterization was confirmed by TEM, FTIR, X-RD analysis and LM-20 analysis.

The antimicrobial activity of synthesised nanoparticles from Punica gratum shows its efficacy

to be a good antimicrobial agent.

Keywords: antimicrobial assay, characterization studies, Punica gratum, silver nanoparticles

INTRODUCTION Nanotechnology deals with the progress in

experimental methods for the production

of nanoparticles of various sizes, shapes

and controlled dispersity.[1]

Nanoparticles

exhibit completely new or improved

properties based on specific characteristics

such as size, distribution and

morphology.[2]

Nanoparticles are of

immense scientific relevance as they

connect the gap between bulk materials

and atomic or molecular structures.[3]

Silver has been special place in the history

of the elements because it is one of the

first five metals discovered and used by

humans.[4]

Ag-NPs have particular

properties that may perhaps have

numerous applications in the fields of

dentistry, clothing, catalysis, mirrors,

optics, photography, electronics, and the

food industry.[5]

Plants and fruit extracts

can be described as nano-factories which

provide potential pathway to

bioaccumulation into food chain and

environment.[6]

Biological synthesis of

silver nanoparticles by using plants,

microorganisms and enzymes, etc. have

been suggested as more eco-friendly

possible alternatives than using physical

and chemical methods,[7]

silver

nanoparticles (Ag-NPs) have a wide area

of interest, as they have a large number of

applications, such as in nonlinear optics,

spectrally selective coating for solar

energy absorption, bio-labelling,

intercalation materials for electrical

batteries as optical receptors, catalyst in

chemical reactions, and as antibacterial

capacities. The medical properties of silver

have been known for over 2,000 years.

Since the nineteenth century, silver-based

Short Review Article: Defence Enzyme-Polyphenol Oxidases

(PPO) in Lycopersicum esculentum (Tomato)

Ankita Singh* Department of Biotechnology, Amity University, U.P., India

Abstract

Tomato (Lycopersicum esculentum) is one of the most important horticultural crops in the

world. In India, tomato is considered as first rank vegetable crop because of its more use.

The action of Polyphenol Oxidases (PPO) on phenolic oxidation has a role to play in the

plant’s defense. This is a short review article on the mechanism and role of PPO in tomato.

Keywords: Lycopersicum esculentum, phenolic oxidation, polyphenol oxidase

INTRODUCTION

Tomato ((Lycopersicum esculentum) ) is

widely in use throughout the world, due to

its various properties, such as, it is easily

processed; the plants can be propagated by

seed or cloned by tip or shoot cuttings; the

plants have a high yield of fruit; there is

reasonable biomass and protein content;

and they are easily grown under

containment. Its production is very

concentrated in semi-arid regions. The

presence of endogenous defense

mechanism, such as, the oxidative enzyme,

Polyphenol Oxidase (PPO), is generally

produced as a reaction to pathogens. It

catalyzes the formation of lignin and other

oxidative phenols that cause the

development of defense barriers, as shown

in figure 1.[1-3]

Fig. 1. Reactions catalyzed by PPO.

(Source: Queiroz et al., 2008)

DEFENCE ENZYME- PPO IN

TOMATO

Browning of the cut surface of some fruits

and vegetables is due to the presence of a

group of enzymes called polyphenol

oxidases.

These enzymes are released by the broken

cells and they catalyze the reaction

between colorless molecules called

polyphenols and molecular oxygen.

This reaction creates colored compounds

and these new compounds can

spontaneously cross react with one another

to form black-brown complexes called

melanins.[2,5]

Polyphenol oxidases (PPOs) (E.C.

1.10.3.2) are ubiquitous copper-containing

enzymes which use molecular oxygen to

oxidize common ortho-diphenolic

compounds such as caffeic acid and

catechol to their respective quinones. PPO-

generated quinones are highly reactive and

may cross-link or alkylate proteins,

leading to the commonly observed brown

pigments in damaged plant tissues and

plant extracts.[3,4]

Drought Tolerance in Pearl Millet- I

Riva Mathur*

Department of Biotechnology, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University,

Rajasthan, India

Abstract Stress tolerance has long fascinated plant biologists as a challenge to understand the mechanism of plant

survival under biotic and abiotic stress conditions. Exposure of plants to abiotic stresses, such as high

salinity, drought, extreme light and temperature leads to major loss in crop productivity. Pearl millet is

one such crop that has been facing drought conditions and less productivity of the crop. This article is a

short review on the different stresses and their effect on crop productivity.

Keywords: abiotic stress, drought conditions, crop productivity, pearl millet

INTRODUCTION Plant growth and productivity is adversely

affected by nature’s wrath in the form of

various biotic and abiotic stress factors.

Abiotic stresses, such as drought, salinity,

extreme temperatures, chemical toxicity and

oxidative stress are serious threats to

agriculture and the natural status of the

environment. Exposure of these plants to these

abiotic stresses leads to major loss in crop

productivity.[1]

All forms of abiotic stress

affect the water relations of a plant on the

cellular as well as whole plant level causing

specific as well as unspecific reactions,

damages and adaptation reactions.[2]

Environmental stresses trigger a wide variety

of plant responses, ranging from altered gene

expression and cellular metabolism to changes

in growth rate and plant productivity. Water

deficit (drought conditions) can be defined as

the absence of adequate moisture necessary for

a plant to grow normally and complete its life

cycle. Water deficit is one of the major abiotic

stresses, which adversely effects the crop

growth and yield.

Generally drought stress occurs when the

available water in the soil is not available and

atmospheric conditions cause continuous loss

of water by transpiration and evaporation.

Drought stress tolerance is seen in almost all

plants but its extent varies from species to

species and even within species. Water deficit

and salt stresses are global issues to ensure

survival of agricultural crops and sustainable

food production.[3]

Drought stress is considered to be a moderate

loss of water, which leads to stomatal closure

and limitation of gas exchange. Desiccation is

much more extensive loss of water, which can

potentially lead to gross disruption of

metabolism and cell structure and eventually

to the cessation of enzyme catalyzed

reactions.[4]

Drought stress is characterized by

reduction of water content, diminished leaf

water potential and tugger loss, closure of

stomata and decrease in cell enlargement and

growth. Severe water stress may result in the

arrest of photosynthesis, disturbance of

metabolism and finally the death of plant.[5]

It has been established that drought stress is a

very important limiting factor at the initial

phase of plant growth and establishment. It

affects both elongation and expansion

growth.[6]

Water stress greatly suppresses cell

expansion and cell growth due to the low

turgor pressure. Osmotic regulation can enable

the maintenance of cell turgor for survival to

assist plant growth under severe drought

conditions in pearl millet.[7]

Effect of Drought Stress on Morphological Characteristics in

Plants- II

Riva Mathur* Department of Biotechnology, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University,

Rajasthan, India

Abstract

Drought conditions significantly affect the growth and development of plants. Various

metabolic functions in plants are also reduced due to such conditions, such as reduction in

plant pigments- chlorophyll and carotenoids and alterations in the expression of certain

proteins. This is a brief review on various effects of drought stress on different morphological

characteristics in plants.

Keywords: carotenoids, chlorophyll content, crop productivity, drought stress, protein

profiling

INTRODUCTION

Drought is an important limiting factor at a

initial stage. It affects both elongation and

expansion phases. Among the crops, rice

as a submerged crop, is probably

susceptible to drought. Pearl millet is

comparatively more drought tolerant than

other cereal crops. In experimental studies,

it was observed that the stem length of

soybean decreased under water deficit

conditions. While, in other studies, it was

found that the plant height reduced upto

25% in water stressed citrus seedlings.

Though, osmotic regulation can enable the

maintenance of cell turgor for survival or

to assist plant growth under severe drought

conditions in pearl millet.[1-3]

Water stress suppresses cell expansion and

cell growth due to low turgor pressure.

The reduction in plant height is associated

with a decline in cell enlargement and

enhanced leaf senescence under water

stress.[4,5]

Development of optimal leaf

area is important to photosynthesis and dry

matter production.

The significance of root system in

obtaining water has for some time been

observed. A productive root system can

aid in plant growth and development amid

the early plant development stage and

obtain water from shallow soil layers that

is generally lost by dissipation in

legumes.[3,5]

The improvement of root

system builds the water uptake and keeps

up required osmotic pressure.

An increase in root to shoot ratio under

drought conditions has also been found to

be related to ABA content of roots and

shoots. [6]

Increased plant fresh and dry weights in

water drought conditions are required

features. A usual disadvantage of water

drought condition on harvest plants is the

decrease in fresh and dry biomass

production.[7]

Plant productivity under

water drought condition is firmly

identified with the procedures of processes

of dry matter partitioning and temporal

mass distribution.[2,3]

Ankita Singh* Department of Biotechnology, Amity University, U.P., India

Abstract

Marigold is an annual herb with pale-green leaves. Flowers in this plant are produced from

the beginning of summer until frost and have a strong but rather unpleasant odor. It also has

anti- inflammatory properties and used in the healing of wounds. This is a brief review article

on the different properties of the plant Tagetes erecta (marigold).

Keywords: Tagetes erecta, properties

INTRODUCTION

The genus Tagetes belongs to the

Asteraceae family and comprises of 56

species, 27 of them annuals and 29

perennials. Tagetes sp. are grown all over

the world as multi-purpose plants of these

species. T. minuta, T. erecta, T. patula and

T. tenuifolia, are some of the most

common species.[1]

Tagetes sp. have been

used in folk medicine to treat intestinal and

stomach diseases and some of them have

been found to possess biological activity.[2]

This genus is recognized as a source of

very interesting biologically active

products, that is, carotenoids used as food

possessing anticancer and anti-ageing

effects[4]

, essential oils known for their

antibacterial and insecticidal properties[5]

and flavonoids having pharmacological

properties.[6]

Volatile oils of T. minuta are

used as antibacterial (Senatore et al.,

2004), flavour components in food

products and as perfumes.[1]

They also

have suppressive biological activity

against some insects and pathogens.[7]

Tagetes erecta is a potential plant whose

essential oil from flowers has acted as an

effective repellent against insects.[8]

Tagetes minuta oil has been found to be

active against carnation ring spot (CaRSV)

and carnation vein mottle viruses

(CaVMV).

According to WHO survey, 80%

populations living in the developing

countries rely almost exclusively on

traditional medicine for their primary

health care needs and pest control.

Exploration of chemical constituents of

different parts of the plants and

pharmacological screening may provide us

the basis for new leads for development of

novel agents. Crushed roots of marigold

(Tagetes erecta) provide good control of

root knot nematodes when applied to soil

in mulberry gardens. Some species in

Tagetes have been widely used as natural

insecticides and fungicides. For example,

the extract from the roots of T. erecta was

lethal or inhibitory to the hatching of

Meloidogyne javanica (Treub) chitwood

and M. arenaria (Neal) Chitwood. The

extracts from some species in Tagetes L.

also exhibit anti-fungicidal activity.

Various oils in plants of Tagetes L. have

been found to inhibit Gram-positive

bacteria and fungi. In addition, flower

pigments in the plants of Tagetes L., as
