Country of Publication: Germany, Federal Republic of Within the framework of the project special cultures of microorganisms were

tested for their efficiency for the degradation of phenol-containing waste

waters from coal upgrading plants. Furthermore, different immobilization methods and reactor types for the use of highly polluted waste waters were

tested. A biotechnical process was developed which is expected to have excellent chances for practical realization on an industrial scale. (ERA CITATION 14:010897)

Extremely thermophilic bacteria grow optimally between 80 and 105 C. They were discovered only recently, little is known of their physiology and biochemistry, and no enzyme has been purified from them. However, they have enormous potential in energy conversions and the production of fuels and chemicals. In this project we are investigating the metabolism of molecular

hydrogen (HZ) by five extremely thermophilic bacteria, selected on the basis

of their remarkable physiology and remote phylogenetic positions. Two have

been isolated from deep sea hypothermal vents. Objectives are to grow these organisms on a large scale in vitro and purify their hydrognases, the enzyme

responsible for catalyzing HZ activation and H2 production, and related redox

proteins. Their molecular and catalytic properties will then be determined by

biochemical and spectroscopic techniques. The long term goal is to asse.ss the biotechnological potential of these enzymes. 2 refs. (ERA citation 14:011821)
