This article reviews, in brief, the important industrial uses of starc
h and starch processing in industry. The other aspects discussed inclu
de the main enzymes involved in starch degradation, commercially avail
able amylolytic enzymes, thermostable enzymes from mesophilic and ther
mophilic microorganisms, microbial fermentation systems used in amylol
ytic enzyme biosynthesis, amylolytic yeasts in ethanol production from
starch, and amylolytic ruminal organisms.
