Abstract: An acid a-amylase hyperproducing strain, designated as . was isolated in a screening procedure from South American soil samples. MIR-61, a 60 "C thermoresistant stmin, was identified using 98 biochemical and morphological tests and characterized as Bacillus lichenifarmis by numerical taxonomy. Batch cultures of B. lichenifornu's MIR-61 showed extracellular a-amylase and a-glucosidase activities during the exponential growth phase. The production of a-amylase was studied at free and constant pH values at 37 an…
