METHOD FOR PRODUCING FROM MICROBIAL SOURCES ENZYMES HAVING MULTIPLE IMPROVED CHARACTERISTICS

摘要

A method of producing from sources of microorganisms enzymes having multiple improved characteristics. Soil samples are collected from a wide variety of sources that are diverse geographically and environmentally. The microorganisms are screened using microbiological screens to select microorganisms that produce enzymes that are active over a broad range of temperatures. Enzymes from selected microorganisms are screened for improved thermostability, extended active temperature range, extended active pH range, extended shelf-life, and improved protease resistance.
