Bioremediation of Organic Detritus
The dissolved and suspended organic matter contains mainly carbon chains and is highly available to microbes and algae. A good bioremediator must contain microbes that are capable of effectively clearing carbonaceous wastes from water. Additionally, it helps if these microbes multiply rapidly and have good enzymatic capability. Members of the genus Bacillus, like Bacillus subtilis, Bacillus licheniformis, Bacillus cereus, Bacillus coagulans, and of the genus Phenibacillus, like Phenibacillus
polymyxa, are good examples of bacteria suitable for bioremediation of organic detritus. However, these are not normally present in the required amounts in the water column, their natural habitat being
the sediment. When certain Bacillus strains are added to the water in sufficient quantities, they can make an impact. They compete with the bacterial flora naturally present for the available organic matter, like leached or excess feed and shrimp faeces (Sharma 1999). As a part of bio-augmentation, the Bacillus can be produced, mixed with sand or clay and broadcasted to be deposited in the pond bottom (Singh et al. 2001). Lactobacillus is also used along with Bacillus to break down the organic
detritus. These bacteria produce a variety of enzymes that break down proteins and starch to small molecules, which are then taken up as energy sources by other organisms. The removal of large organic compounds reduces water turbidity (Haung 2003).
