Purple non-sulfur bacteria (PNSB) are well known for their ability in transforming organic substrates own source of nutrients. The nutritional values leafy vegetable waste could be improved through bioconversion with PNSB. This study was conducted to access status bio-converted product and efficacy derived as aquaculture feed supplement. Proximate compositions wastes were after 6 days 30% inoculums Afifella marina strain ME (KC205142). crude proteins (%) ashes increased 51.7% 19.6% respectively. On the other hand, fiber decreased by 21%. During feeding trial Tilapia (Oreochromis niloticus), no significant differences observed intake (g/fish/day), but value conversion ratio weight gain among used diets. However, lower ingestion rate (g/d/fish) better obtained while fishes fed diet composed commercial mixed 5% product. higher only diet. There FCR (D5) 10% (D10) can a promising approach open new market segment aquafeed industry.
