Abstract
A thermostable lipase is produced by aerobically culturing a microorganism having the identifying characteristics of Bacillus sp. A30-1 ATCC No. 53841 on a nutrient medium under growth conditions until a recoverable lipolytic activity is detectable and thereafter isolating the thermostable lipase. The thermostable lipase has an optimum pH of 9.5, an isoelectric point of 5.15, a molecular weight of about 65,000 and retaining approximately 100% of its original activity upon being heated at 75.degree. C. for 30 minutes.
