HALOPHILIC AND ALKALIPHILIC MICROORGANISMS AND SALT AND ALKALI TOLERANT ENZYMES ISOLATED FROM CULTURES OF THEM

摘要

Haloalkaliphilic bacteria have been isolated from samples of soil, water, sediment, trona (NaHCO7+/-Na6CO7+/-2H6O) and a number of other sources obtained from in and around hypersaline soda lakes. These bacteria have been analyzed according to the principles of numerical taxonomy with respect to each other, as well as to other known haloalkaliphilic bacteria. In addition, these bacteria are further circumscribed by chemotaxonomic analysis. The bacteria produce various alkali- and salt-tolerant enzymes which may be used in various industrial processes requiring such enzymatic activity in a high pH, saline environment.
