Value-added food: Single cell protein

Digestion of food depends on three main factors: (i) the ingested food and the extent to which the food is susceptible to the effects of digestive enzymes, (ii) the activity of the digestive enzymes and (iii) the length of time the food is exposed to the action of the digestive enzymes. Each of these factors is affected by a multitude of secondary factors. The present review highlights the experimental results on the secondary factor, enzymatic activity and possible contribution of the fish gut microbiota in nutrition. It has been suggested that fish gut microbiota might have positive effects to the digestive processes of fish, and these studies have isolated and identified the enzyme-producing microbiota. In addition to Bacillus genera, Enterobacteriaceae and Acinetobacter, Aeromonas, Flavobacterium, Photobacterium, Pseudomonas, Vibrio, Microbacterium, Micrococcus, Staphylococcus, unidentified anaerobes and yeast are also suggested to be possible contributors. However, in contrast to endothermic animals, it is difficult to conclude the exact contribution of the gastrointestinal microbiota because of the complexity and variable ecology of the digestive tract of different fish species, the presence of stomach and pyloric caeca and the relative intestinal length. The present review will critically evaluate the results to establish whether or not intestinal microbiota do contribute to fish nutrition.

Pathological changes in Fenneropenaeus indicus experimentally infected with white spot virus and virus morphogenesis

For the first time in India a cell culture system from the eye stalk of Penaeus indicus has been developed by a simple technique. On repeated trials 100% reproducibility could be obtained and the cell cultures developed could attain 100% confluency in plasdc bottles. The medium used for the development consisted of Leibovitz (L-15) 45%, (2X) (HIMEDIA, Bombay), supplemented with 18% foetal bovine serum (FBS), 27% prawn muscle extract (PME), 10% prawn haemolymph (PHL) and antibiodc mixture consisdng of penicillin, streptomycin sulphate and chloramphenicol. pH of the medium was adjusted to 6.8 to 7.2 and the osmolarity 720 ± 10 mOsm and the temperature of incubadon was 25°C. The cell culture development could be attained in closed system as well as in open system in a CO2 incubator in an atmosphere of 5% CO2. Interesdngly in all instances cell proliferadon and migration from the expiants and formation of monolayer could commence within 24 hours and the cultures developed could be maintained for more than 60 days without fluid change. The cells developed were epitheloid like with intracellular granules.
