ISOLASI DAN IDENTIFIKASI BAKTERI SHIMBION SPONS PENGHASIL ENZIM AMILASE ASAL PANTAI MELAWAI BALIKPAPAN
Has been conducted research about isolation and identification bacterium symbionts sponge as producer enzyme amylase from Melawai Beach of Balikpapan. Targeting know is sponge type, symbionts bacterium group and test ability of sponge symbionts bacterium as amylase enzyme producer. Research expected to give information about existence of sponge and micro symbioning it’s from Melawai Beach. Research executed in four phase namely analysis sponge morphology, macroscopic analysis of isolate, microscopic analysis through coloration of bacterium symbionts, and test ability of symbion bacterium in yielding amylase enzyme. Result of morphology analysis is Callyspongia sp species enter in Callyspongiidae of family relatives, while perceived by microscopic and macroscopic perception of symbion bacterium in form of small bar, ellipse, surface flatten, colony disseminate, ruddle, fastening safranin colour designate the bacterium is negative gram. Perception of activity amylase enzyme at MA medium show colony have amylase activity marked with formed it’s of transparent zone at MA media colony if dropped by iodium condensation. Activity of amylase very high happened it thinning 10-2 marked with the existence of formed by zone of transparent very wide of around colony. Result of research concluded that t sponge is Callyspongia sp species, symbionts bacterium group is negative gram and bacterium represent producer of amylase enzyme
