Aquaculture produces different kinds of wastes depending upon the species farmed and the farming practices adopted. The physical, chemical and biological conditions of the culture environment have a negative influence like toxins hydrogen sulphide, ammonia and carbon dioxide leading to stress and ultimately disease. To improve water quality and the immediate environment of fish and shrimp, probiotics are applied directly to the ponds which is termed as bioaugmentation Enzymes produced by Bacillus such as carbohydrase, protease, lipase, trypsin are efficient at metabolizing a large range of lipids, proteins, and carbohydrates and this is one of the reasons for their choice as probiotics to improve digestive enzyme activities. Our aim is to optimize the medium for maximum cell density and higher production of hydrolytic enzymes present in Bacillus cereus, performing the animal studies and scaling up the process in a fermenter.
