白酒丢糟的多菌种混菌固态发酵制备有机肥
Optimization on Process Condition in Solid-state Fermentation of Vinasse for Organic Fertilizer
摘要
Abstract
Small experiment was carried out at room temperature for the production of organic fertilizer using the grains of liquor as the cartier.In this experiment,wheat bran and distillers grains were used as substrates,4 kinds of bacillus and 2 kinds of fungi and yeast were used as the strains for fermentation.This experiment explored the optimum conditions of the solid-state fermentation for organic fertilizer through the single factor tests and response surface method according the content of humus,nitrogen,phosphorus and potassium in the fermented product.The conditions included mainly the initial water content,vinasse content and the initial pH.According the verification test,the actual value was consistent with the estimated value,and the optimum conditions were confirmed.The optimum conditions were that initial water content was 60.54％,content of vinasse was 52.06％,the initial pH was 7.03,the initial inoculum was between 3％ and 5％,the duration of fermentation was 6 days,and the finally the humus content in the fermented product was 17.50％,germination index,GI was 93.2％,E4/E6 was 2.19.关键词
