Embodiment Construction

[0026] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0027]Microorganisms in nature are extremely abundant, and under the action of natural selection, they form relatively stable communities with specific functions through interactions such as competition, antagonism, and mutual benefit. In the process of decomposing complex compounds, the bacterial population of complex compounds can be used to synthesize a variety of hydrolytic enzymes through substrate induction, and decompose substrates into small molecular compounds for their own growth. In this process, due to the lack of substrates, they cannot The growing population is inhibited, or even completely eliminated, and finally forms a dominant synbiotic flora with a certain synergistic effect. The present invention utilizes this process, adopts the subgeneration continuous culture method, and uses wheat straw as the sole carbon source to separa...

Abstract

The invention relates to a cellulose degradation composite flora which is composed of bacterial species and fungal species. The composite flora horizontal bacterial community is mainly composed of fontibacillus, stenotrophomonas, paenibacillus and pantoea; and the fungal community is mainly composed of petromyces and nectria. The composite flora is obtained by adopting a subculture continuous culture method; wheat straw is added into a Mandels culture medium to serve as a unique carbon source and is obtained by screening litters under a perennial pinus sylvestris forest in a Maowusu sandy land; and the composite flora can be used for innocent treatment and resource utilization of agricultural wastes such as phellinusribis bran. The method overcomes the defects of low efficiency, poor constant value, weak competitive capacity with indigenous microorganisms, non-ideal practical application effect and the like of cellulose degrading bacteria in practical application in the prior art, is suitable for decomposing and composting phellinusribis bran which is difficult to degrade, and can quickly and efficiently realize harmless treatment and resource utilization of the agricultural wastesdifficult to decompose.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a microbial flora for rapidly decomposing agricultural waste, especially fungus chaff, in particular to a cellulose-degrading composite flora and its application for screening and decomposing wood-rot fungus chaff. Background technique [0002] The intensification and large-scale development of modern agriculture has broken the balance of the recycling of traditional agricultural waste. The rapid development of the edible fungus industry has resulted in a high increase in the production of fungus chaff, which has multiple uses, such as raw materials for raising animals, bioremediation substrates, and fertilizers, etc., but its production still far exceeds its utilization. However, due to the lack of effective treatment measures, a large amount of fungus chaff produced by the edible fungus industry will cause serious environmental problems. Bacteria chaff contains a large amoun...
