摘要：This experiment was conducted to determine the possibility of utilization of vegetable waste juice in the production of purple non-sulfur bacterium Afifella marina biomass. Bacterium was cultured in four diluted such as, 10%, 20%, 30% and 40% (v/v) vegetable waste juices. In addition synthetic 112 media were used as control to compare the growth characteristics of Afifella marine. The bacterium Afifella marina grew well in 10% diluted vegetable waste juice in anaerobic light condition with the highest production of 5.02 g/l dry cell weight in fifth day of culture, whereas the highest total carotenoid production of 0.87 mg/g dry cell weight was recorded in third day of culture. The highest dry cell weight productions recorded in 10% of VWJ was significantly higher compared to four other treatments (F = 14.63; p = 0.00). However, the total carotenoid production of bacteria in 10% VWJ showed no significant difference compared to the carotenoid production in 112 synthetic media, but was significantly higher compared to three other treatments (P = 0.00). The bacterium, Afifella marina has the ability to use vegetable waste juice at certain level for the production of bacterial biomass.
