Screening of substrates and strains for producing single cell protein by fungal fermentation in distillery waste
摘要
Abstract
To utilize distillery residue to produce value-added products,the productions of single cell protein(single cell protein,SCP)from various substrates and strains were investigated. Yellow winery residue(yellow wine lees and rice wastewater)and cassava distillery residue(cassava stillage and its supernatant)were chosen as four kinds of fermentation substrates. Meanwhile Candida utilis and Geotrichum candidum were chosen as strains. Batch fermentation was applied to study the effect of substrates and strains on SCP production. The experimental results showed that yellow winery residue was suitable for SCP production. The maximum SCP yield was 90.22g/L with production rate of 3.91 and crude protein content of 53.3%,after 4 days of fungal fermentation via Candida utilis and Geotrichum candidum co-culture in 6% yellow wine lees-rice wastewater substrate.Furthermore,the synthesized SCP product contains essential amino acids,which could be widely used as animal feed in the future.关键词
