Production and Characterization of Thermostable

Amylase Produced from Spore Former Thermophilic

Bacilli Isolated and Screened from Teff (Eragrostis teff)

Starch Rich Soil

Berhanu Tsehai Andualem* Department of Biotechnology, University of Gondar, Ethiopia

Abstract There is a need to isolate and screen amylase-producing bacilli bacteria from soil rich in content of teff starch at high temperature environment. Therefore, the aim of this study

was to isolate and screen amylase-producing bacilli isolates and characterization of their

optimal amylase activities. Amylase-producing bacilli were isolated and their enzymes characterized. Effect of temperature, pH, substrate and salt concentration were

determined. All isolates have clear zone over 15 mm and hydrolyzed greater than 90% of starch after 60 h of fermentation. There was no significant (p ≥ 0.05) variation in enzyme

productivity. Aamylases activities of G1 and G3 isolates reached their optimum at 60 °C

but G2 was at 55 °C. Amylase from isolate G1 and G3 showed hydrolysis capacity of 96.84 and 97.62%, respectively, while G2 was 99.68% at 55 °C. Optimum enzyme

activity of G1, G2 and G3 isolates was 100, 100 and 99.75% at pH 8, respectively.

Thermal stability of all amylases was retained above 92%, while pH, G1 and G2 were above 86.37% but G2 was 82%. Thermophilic, alkalophilic and halophlic amylases have

wide range of huge potntial for industrial applications.

Insecticidal Activity of Rotenone in Brebra (Millettia

Ferruginea) Oil Refinery Residue against Different Stored

Crop Insect Pests and its Prospect to Apply as Pest

Control Substance

Berhanu Tsehai Andualem* Department of Biotechnology, University of Gondar, Ethiopia

Abstract Use of botanical insecticides against stored crop insect pests is environmental safer and

eco-friend alternative method for crop protection. The objective was to investigate insecticidal potential of oil refinery residue with rotenone against selected insect pest of

stored crops. The amount of rotenone from samples was determined by HPLC. The toxicity of the rotenone from residual extract and non-defatted sample were tested

against. Acanthoscelides obtectus, Sitophilus zeamais and Tribolium castaneum using

standard methods. 1, 1.5 and 2 ml residue contains 1037.089, 1555.98 and 2075.57 µg rotenone, respectively. Significant differences (P ≤ 0.01) were observed among different

doses of treatment for % mortality of Tribolium castanium and Sitophilus zeamais after

24 h of treatment but, there was no significant difference (P ≤ 0.01) at doses of 2 ml of residues against Tribolium castanium and 1.5 ml against Sitophilus zeamais after

treatment of 24 h. Tribolium castanium seems to be more resistant than Sitophilus zeamais and Acanthoscelides obtectus for rotenone from oil refinery residue. Any way

2 ml of oil residue has potential to kill 100% of tested pests after 24 h of treatment.

Therefore, the toxicity of the different extracts to tested insects was dose dependent, however, the mortality as compared to control was significant (P<0.001). So, residue

from refined oil has huge potential of insecticidal activity and can serve as insect

pesticide at high concentration level. It is economically important for insect crop pest control in one hand and save the money spent for inorganic insect pest chemicals and

thereby reduces environmental impact of non-degradable chemicals.

Designer Zinc Finger Nuclease: A Versatile Tool for

Genome Editing in Animals

Kiran Lakkireddy*, Sudhakar Podha, Krishna Satya A, Kasturi K, Sambasiva Rao KRS Department of Biotechnology, Acharya Nagarjuna University, Nagarjuna Nagar-522510,

Guntur, Andhra Pradesh, India

Abstract In this review, is provided an update on the most popular approaches, including zinc finger nuclease (ZFN)-based gene editing by homologous recombination (HR), gene

knockout, non-homologous end joining (NHEJ), and gene therapy in mouse. Zinc finger nucleases (ZFNs) are synthetic restriction enzymes evolved by fusing zinc finger that

facilitate genome editing by creating a double-stranded break in DNA at a user-specified

location. ZFNs are new tools that promise to radically simplify gene knockout, targeted gene deletions and replacements, because of their high specificities. Most recent

strategies for developing ZFNs with customized sequence specificities require the construction of numerous tandem arrays of zinc finger proteins (ZFPs) to target genes

specifically, also added more fingers (up to six per ZFN) to specify longer and rare

cleavage site. The classical synthetic Cys2His2 zinc finger domains (C2H2 ZFs) with engineered DNA-invoking specificities have shown promise for application in biological

research. Current methods of an engineered ZFN design, the important use in

modification of the mouse genome, and innovative applications of this technology in mouse will be discussed. Targeted genome inactivation of endogenous immunoglobulin

genes in combination with addition of human immunoglobulin genes has been achieved

in mice. A light-activated ZFN will competence the conditional generation of gene knock-

ins and knock-outs with unique accuracy. ZFNs are useful to generate precisely targeted

genome edits resulting in cell lines including somatic cell lines with targeted gene deletions, integrations or modifications. ZFN-mediated site-specific mutagenesis have

been proven to be effective in many model organisms – arabidopsis, drosophila, zebrafish, caenorhabditis elegans, rabbit and mouse.

Abstract Studies suggest that approximately 4.6 million ton of pigmentary titanium dioxide (TiO2) is consumed annually worldwide. Owing to the increased industrial and consumer

applications, there is growing concern regarding the possible risk associated with their

environmental exposure. TiO2 dust, when inhaled, has been classified by the International Agency for Research on Cancer (IARC) as an IARC Group 2B

carcinogen, meaning it is possibly carcinogenic to humans. TiO2 nanoparticles (NPs) can enter the aquatic environment either through direct or indirect release as effluents from

nano-paints, sunscreen lotions, food additives, medical use, dismantling of batteries, etc.

Therefore, the aim of the present study was to explore the difference in toxicity mechanism of TiO2 NPs at low concentrations (1 μg/ml), in a bacterial consortium

consisting of Pseudomonas aeruginosa, Bacillus altitudinis and Bacillus tequilensis, isolated from lakewater sediments, under light and dark conditions. The cytotoxicity of

the NPs was studied by performing several biochemical assays for the assessment of

membrane permeability, cell viability, oxidative stress and secretion of exo-polysaccharides. It was found that there was generation of ROS, which may have resulted

in the decrease in cell viability. Also, the cytotoxic effects were found to be more

pronounced under dark than under light conditions.

Keywords: titanium dioxide nanoparticles, cytotoxicity, ROS

Forward Osmosis Membrane Concentration Process

of Anthocyanins from Pomegranate Fruit

Chetan A. Nayak* Department of Chemical Engineering, BMS College of Engineering,

Bangalore, India

Abstract The production of concentrated pomegranate juice was investigated by using forward

osmosis membrane concentration process. Suspended solids were completely removed in the clarification step, while soluble solids and organic acids were concentrated using

forward osmosis membrane process. The processes was performed at ambient

temperature (25 ± 2 °C) and non pressure driven process to produce a concentrated

extract to a total soluble solids (TSS) content of 60 Brix from an initial concentration of

4 Brix (15 times increase). The antioxidant activity of pomegranate aril juice, attributed

to a great extent to total phenols and anthocyanins content, was efficiently preserved during the concentration step independently on the achieved level of total soluble solids.

Non-enzymatic browning index and degradation constant for thermally concentrated sample were found to be approximately two (0.78–0.35) and eight (63.0×10

−3 to

8.0×10−3

day−1

) times, respectively, as compared to the concentrate produced by forward

osmosis. An integrated membrane process scheme for the production of concentrated pomegranate juice with potential applications for food, pharmaceutical and cosmetic

sectors was proposed.

Abstract In the present study, the production and characterization of biosurfactant by an

indigenous Bacillus methylotrophicus USTBb (GenBank accession no. KF496216) was

investigated. This bacterial strain was isolated from crude oil contaminated aqueous medium was identified to be a persuasive producer of biosurfactant using crude oil as the

sole carbon and energy source. Growth parameters were optimized, with the aim of increasing biosurfactant productivity. Maximum biosurfactant production (5.5 g L

-1) by

strain USTBb was reached after 12 d of incubation time and was found to be growth-

associated. The strain was able to reduce the surface tension of its cell free culture supernatant containing biosurfactant to 28 mN m

-1. Biosurfactant exhibited excellent

emulsification activity against crude oil when compared with various tested hydrocarbon and vegetable oil and it possessed a low critical micelle concentration (CMC) value of

approximately 35 mg L-1

, indicating high surface activity. USTBb biosurfactant showed

stability under extreme environmental conditions such as high temperature, pH and salinity. Elemental compositions and thermal analysis of biosurfactant was determined

by X-ray photoelectron spectroscopy (XPS) and thermal gravimetric (TG) respectively.

Furthermore, biosurfactant was found to be an antimicrobial agent against gram positive and Gram negative bacterial strains. Studies on the crude oil recovery using

biosurfactant produced by Bacillus sp. USTBb suggested its prospective relevance in

microbial enhanced oil recovery (MEOR) and bioremediation.
