A new mesophilic Bacillus cereus strain, isolated from soil in North India, produced pullulanase and α-amylase extracellularly. While α-amylase activity increased with temperature and pH up to 42°C and 7·0, pullulanase activity was maximum at 37°C and pH 5·0. This maximum was reached after 12 h and was higher than in thermo-philic bacilli. Raw carbon sources such as wheat flour and maize flour were suitable for growth and enzyme production.
