Single Cell Protein (Scp) Production from Marine Lactobacillus spp.

Background: The Single Cell Protein (SCP) production technologies arose as a promising way to solve the problem of protein shortage in worldwide, which mainly used in human foods or animal feeds. For future success, the animal proteins are expensive protein source in fish feeds and there has been considerable interest in replacing all or part of the fish meal in aquaculture feeds with SCPs. Collectively, studies indicated that SCPs were suitable ingredients for farmed fishes. The Lactobacillus fermentum strain used in this study was surprising to note a single strain contains 20 amino acids. In this study the strain used and seemed to be ideal in the above respects. Further research on industrial scale production of SCP using this strain using cheaper sources (or) sewage is warranted.  
Methods: In this field – laboratory investigation during 2015-2016, the soil samples were collected from the Velar estuary, Tamil Nadu. About 25 colonies were selected and inoculated in to MRS broth. The completed preparation was observed under microscope for motility of the bacterium. Different biochemical characteristics test analyzed by using standard protocol. The antimicrobial effects were determined by the agar diffusion method. Finally the biochemical parameters were analyzed by using standard procedure. 
Result: Our investigation is evident that, the strain very well can be used a probiotic for human and animal nutrition. The isolated strains were found to be non-motile and non-spore farming. Lactobacillus fermentum contains 60-80% of protein, 7-8% of carbohydrate, 2-3% of lipid and 8-9% of nucleic acid contents. The Lactobacillus fermentum strain used in this study showed a high level of inhibitory activity against all the pathogens tested. SCP cannot compete with soya, alfalfa or fish meal. Mushroom production from lignocellulosics seems to be one economical and promising use for SCP.
