โฆ Synopsis
Bacillus alcalophilus subsp, halodurans ATCC 21591, Bacillus sp. NCIB 11203 and Bacillus sp. IMD370 are obligate alkalophiles and produce alkaline a-amylases with maxima for activity at pH 10.0.
All three organisms yielded maximum amylase activity in a medium containing starch as a carbon source and yeatex as a nitrogen source with an initial pH 10.0.

There are few yeasts, which produce extracellular amylase. I n our laboratory, studies on amylase of yeast have been continued. The subjects have been studied in earlier periods with E.ndomycopsis fibuliger ( l ) , and in later periods with Endornyces species ( 2 , 3 , 4 ) . The production of amylas
