Preparation of bio-fermented feed by solid state fermentation of different pretreatment bagasse mixed bacteria
In this study,bagasse after different pretreatment was used as solid fermentation medium,filamentous fungi secreting cellulase and single cell protein producing bacteria were used for mixed solid fermentation,and the effects of different pretreatment bagasse on the quality of bio-fermented feed were investigated.The results showed that different pretreatment bagasse had a great effect on the nutritional value of the prepared bio-fermented feed.Using bagasse,instantaneous steam blast treatment and continuous steam blast treatment bagasse as the substrate of solid fermentation medium was not conducive to the utilization of cellulose and hemicellulose in non-grain biomass raw materials by Aspergus niger and Kluyveromyces marques.Its microbial protein content was low and its nutritional value was low.Using bagasse treated by instantaneous steam blasting and bagasse treated by continuous steam blasting as the substrate of solid fermentation medium,the bio-fermented feed was prepared with high microbial protein content,crude protein content reached 22.07%,amino acid content reached 16.06%,and Huyveronyces marxiae content increased to 7.4×108 CFU/g,which showed high nutritional value.
