The invention mainly relates to
microorganism fermenting methods, in particular to a method which prepares a
solid FGR microbial inoculum that combines
yeast fusion strain (F306),
geotrichum candidum link (G361) and
rhizopus stolonifer strain (R) by utilizing
wastewater and waste residue generated in food industries as well as application thereof. A
solid culture medium of the
solid microorganism microbial inoculum comprises following dry components by weight percentage: 50 to 80 percent of scum residue, 15 to 30 percent of
corncob powder, 8 to 12 percent of
bran coat, 0.5 to 0.8 percent of
corn meal, 0.1 to 3 percent of ureophil and 0.2 to 4 percent of
ammonium sulfate, fresh
wastewater of bean curd, bean vermicelli,
corn starch or yam
starch is added for leading the weight percentage of water to be 45 to 65 percent,
limewater with the concentration of 1 percent is used to adjust pH value between 5.5 and 6.5, a mixed strain liquid of the
yeast fusion strain, the
geotrichum candidum link and the
rhizopus stolonifer strain with the weight 8 to 12 percent of the total dry components is added and completely agitated, ventilated agitation and
fermentation are implemented in a fermenting
pool with dual purposes of fermenting and
drying at the temperature of 28 to 32 DEG C for 18 to 24 hours, and hot air is led into the fermenting
pool at the temperature of 40 to 60 DEG C for
drying, thus producing the solid microbial inoculum that has great application effect in addition agents of beast and bird feedstuff.
