Abstract

The invention provides a fermentation culture medium, a fungus chaff fermentation bacterium agent and a fermentation method and relates to the technical field of application of microorganism resources. The fermentation culture medium provided by the invention can be used for effectively stimulating the germination of spores and the growth of thalli when being used for culturing white rot fungi and aspergillus niger; the enzyme activity of a ligninolytic enzyme produced by the white rot fungi is relatively high and the enzyme activity of cellulase produced by the aspergillus niger is relatively high. According to the fungus chaff fermentation bacterium agent provided by the invention, the fermentation culture medium provided by the invention is used for culturing optimized combination of the matched white rot fungi and aspergillus niger, and cellulose and lignin long chains are easy to crack, so that microorganisms are easy to degrade, a degradation process is accelerated and the degradation time is shortened. According to the fermentation method of fungus chaff, provided by the invention, the fungus chaff is fermented by utilizing the fermentation culture medium provided by the invention; the fermentation method is simple and convenient to operate, easy to implement and economical and practical.

Description

technical field [0001] The invention relates to the technical field of the application of microbial resources, in particular to a fermentation medium, a fungus chaff fermentation agent and a fermentation method. Background technique [0002] Mushroom chaff refers to the culture medium waste produced after the cultivation of edible fungi, mainly composed of crude fiber, crude protein and crude fat. With the rapid development of the edible fungi industry, more and more fungus chaff is produced after the production of edible fungi. At present, China is the world's largest producer of shiitake mushrooms, with an annual output of 1.68×10 dried mushrooms. 7 kg. While the mushroom industry brings economic benefits, it also brings resource waste and environmental pollution. Every time 100kg of fresh mushrooms are harvested, 60kg of fungus chaff will be produced. These fungus chaffs are rich in nutrients and are easy to spoil and deteriorate. waste of resources and pollute the en...
