Effectiveness of using of brown algae alginate to immobilize the indigenous bioremediation bacteria for reducing waste water from shrimp culture

Abstract Bacillus coagulans T1.2, an indigenous bacterium from shrimp ponds in East Lampung, has been found to reduce total ammonia nitrogen (TAN). The purpose of this study was know the effectivity immobilization bacterial by sodium alginate marine brown algae wastewater pollution culture. algae, Sargassum sp. and Padina sp., were collected Pesisir Barat Ketapang beach, Lampung. Alginate extracted both alkali method. beads made mixed suspension with (1:3 v/v) formed 1,5 ml syringe without needle. In vitro study, immobilized bacteria submerged artificial (2 -1 ) incubated for 20 days. control group includes same immobilization. TAN measured viability evaluated after incubation period. results showed that using as a matrix effectively significantly content Total Ammonia Nitrogen (TAN) wastewater. better than treatment
