This thesis focused on promoting effect of Bacillus subtilis, Saccharomyces cerevisiae, Trichoderma reesei and Aspergillus niger on Livestock manure compost process and their interaction. We found the most beneficial microbe combination for pig excrement compost and the Proportion of starter cultures as Bacillus subtilis: Aspergillus niger: Trichoderma reesei= 3:2:3, the Saccharomyces cerevisiae did not play an obvious role during the wanning process. But the results of pilot scale trial showed that, The compost maturate in 10 days with this microbe combination, and the GI of pig excrement compost products had been increased by 21.7%.By using of the Ferment as listed, this article makes a further research on the industrial fermentation process of pig excrement into organic fertilizers, for saving amount of accessory and accelerating the time of maturity. The first step is, adding 30% of chaff powder. After composted, according to the ratio of 1:1, we can add some fresh pig excrement and little accessory for the second composting. This process repeated four times. On the end, the production looks loose and puce, smells strongly, the Organic content has been bigger than 30%, the GI of compost products has been more than 50%.In our study, we add organic fertilizer into the Coprinus comatus and Volvariella volvacea by grads. The results suggested that the speed of hypha extending had been increased by 14.7% and the harvest time had been shorted by 2 day after added 30% organic fertilizer into culture medium of Coprinus comatus; the output of Volvariella volvacea had been increased by 24.4% and the harvest time had been shorted by 2 day after added 10% organic fertilizer into culture medium of Volvariella volvacea.
