Abstract: This thesis Entitled Studies on amylolytic bacteria in cochin backwaters.This thesis presents a detailed account of the disribution of amylolytic bacteria in water. sediment. fishes ( Etroplus suratensis and Liza parsia) • prawns ( Penaeus indicus and Metapenaeus dobsoni) and clams ( Sunetta scripta and Meretrix casta) from Cochin backwaters. genera-wise distribution of amylolytic bacteria, ability of selected strains to grow and produce amylase at various physico-chemical conditions. Regulation of amylase synthesis anrt characters of amylases producer by these halophilic bacteria.Amylolytic bacteria are distributed widely in water. sediment. fishes. prawns and clams of Cochin back waters. 53% of the total isolates tested were capable of producing amylase. Maximum number of arnylolytic bacteria were present in Metapenaeus dobsoni. In general, the gut region of aquatic animals harboured more amylolytic bacteria than the gill or surface. These bacteria may help in the digestion of starch present in their food.Presence of ions in the medium was found to be essential for growth and amylase production. It was found that this ionic requirement is not highly specific. Sorlium chloride could be replaced by potassium chloride. or magnesium chloride to some extent I without affecting growth and amylase production. The important function of these ions may be to maintain the osmotic balance between the cells and their environment.All the isolates showed the ability to grow and produce amylase using raw-starches from cassava. plantain and potato .This property suggests their role in the rdegradation of native starches in the environment
