Differential Heat Stabilities of Bacillus Amylases

Abstract

Seventeen cultures representing eight strains of Bacillus coagulans and twelve cultures representing eight strains of Bacillus stearothermophilus did not yield a culture that would produce amylase at both 37 and 55 C.on July 31, 2020 by guest

Some aspects of a 1,4-β-?-xylanase and a β-?-xylosidase secreted by Bacillus coagulans strain 26

“…The isolate was maintained on slant tubes containing yeast extract 1%, glucose 1% and agar 2% at 4°C. B. coagulans ATCC8038 was a gift from Dr. Paul A. Hartman (Iowa State University, Ames, IA, USA) [3] and was used as reference throughout the present work. Growth of the isolate was carried out on petri dishes filled with 15 ml of YNBXA medium consisting of 0.6% yeast nitrogen base (Difco), 2.5% xylan (Sigma Chemical Co.) and 2% agar (Difco).…”
