Abstract:

Exploring food waste recycle as a starting point and the cafeteria food waste was the research object in this paper. After solid-liquid separation, the feasibility of cultivation fermentation of Rhodotorula glutini in the waste liquid and obtaintion of the bacteria had been studied. At last, the efficiency of biological fertilizer including soild waste and fermentation bacteria had been researched in soybean. The results showed that, Rhodotorula glutini could make use of food waste. The dry weight of bacteria was 12 g/L when it had been fermented 24 h in optimal level. The pH value of 5.5 was the best conditions. Moreover, solid waste and bacteria could promoted the growth of soybean shoots when use 450 kg per 1 m2.
