Bioconversion of Mango Processing Waste to Fish-feed by Microalgae Isolated from Fruit Processing Industrial Effluents.

Fifteen different strains of blue green algae (including one green algae) collected from the wastewaters of fruit
processing industrial areas were screened for production of algal biomass from mango processing waste. The utility of
micro-algae was evaluated based on feeding trials of the biomass to the fish Tilipia mossambica. Only the growth of fish in
terms of body mass gain was measured. The mango waste after removing the stones was macerated, and then diluted with
water to 15-20 per cent mango waste and inoculated with blue green algae. The cultures were continuously illuminated (4000
lux light intensity) for 15-20 d. Among various strains of algae tested, only two (Scytonema sp and Microcystis sp) were
found to be toxic while several others gave promising results. Through such efforts mango waste could be converted into
fish-feed and then through fish growth into important protein source for human consumption.
