柑橘皮渣发酵蛋白质饲料(SCP)工艺优化及光照对发酵饲料的影响
Process Optimization of SCP Fermented from Citrus Wastes and Influence of Light Intensity on SCP
摘要
Abstract
[Objective] Efficient utilization way of citrus wastes was explored.[Method] Taking citrus wastes as raw materials,combined with agricultural by-product wheat bran as auxiliary material to produce single cell protein (SCP)feed.Candida tropicalis,Trichoderma konigii,Aspergillus oryzae,Torulopsis globosa were used as fermentation strains,optimum strain and mixing ratio were studied.[Result] The best strains mixed proportion for fermentation was C.tropicalis:T.konigii:A.oryzae =2∶ 2∶ 1.One-variable method was used to optimize fermentation conditions.The experiment conditions were as follows:fermentation time 84 h;fermentation temperature 33 ℃;moisture content 70 %;microbial added concentration 0.4 mL/g.The crude protein,crude fat and crude fiber content were 35.03%,4.92% and 12.08% respectively.In addition,the influence of light intensity on fermentation feed indicated that when light intensity was 1 000-2 500 lx,the production capacity of protein and fat by microbial were promoted;as light intensity was 10 000 lx,the production capacity of protein and fat by microbial were restrained.In addition,illumination had both acceleration and inhibition on non-photosynthetic microorganism for fermentation of feed.[Conclusion]The research can provide an important theoretical guidance of citrus waste recycling utilization for agriculture.关键词
