EXTREMOPHILIC HOMOCETOGENIC BACTERIA: PHYSIOLOGY, METABOLISM AND BIO-TECHNOLOGICAL POTENTIAL

The work covers the homoacetogenic bacteria of the extremophilic inhabitation places. The aim is to study the special features of the physiology and metabolism, regularities of their existence in the thermophilic and halophilic associations, to study the possibilities of their application in the bio-technology as acetate producers. It has been determined that the special physiological-biochemical features of the homoacetogenic bacteria determine their key role in the extremophilic microbic associations. The factors regulating the growth and activity of the key matabolism enzymes have been revealed. It has been specified that the catalytic properties of the hydrogenases determine their ability to the hygrogen metabolism. The role of the natrium energetics as a procedure of providing energy among extreme-halophilic bacteria has been specified. The biocatalytic system of creating acetate at the expense of conversing gas substrates on base of the immobilized cells of the thermophilic acetogenes has been developed that is a supposition for creation of the new bio-technologies.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
