Abstract
Gram-negative bacteria, which are obligate alkaliphiles, have been isolated from samples of soil, water and sediment and a number of other sources obtained from in and around soda lakes. These bacteria have been analyzed according to the principles of numerical taxonomy with respect to each other, as well as to a variety of known bacteria. In addition, these bacteria are further circumscribed by an analysis of various chemotaxonomic characteristics. The bacteria produce various alkali-tolerant enzymes which may be used in various industrial processes requiring such enzymatic activity in a high pH environment.
