The invention belongs to the field of agricultural insect pest biological control, in particular to a root-knot nematode biological control microbial inoculant and a production process thereof. The present invention overcomes the problems of unsatisfactory control effect, poor specificity, short control effect time and large pollution in the prior art. The technical solution of the present invention is: a root-knot nematode biocontrol agent, which is composed of the following raw materials in parts by weight: 10-15 parts of Acremonium fungus powder, 20-30 parts of zeolite, and 50 parts of diatomite -60 parts, 5 parts chitin and 5-10 parts bran. The present invention is a microbial inoculant containing Acremonium spores which have the functions of infecting and killing biological control of root-knot nematodes, and can be used for biological control of serious-harmful root-knot nematode diseases in the process of planting vegetables and fruits in agricultural facilities. The control effect on root-knot nematodes such as peppers, tomatoes and cucumbers can reach more than 93%.

The invention discloses endophytic fungi from huperzia serrata. The invention is obtained through being separated from the living body of pteridophyta huperzia serrata by adopting endophytic fungi separation and purification technology, and is identified through biosystematics to be acremonium endophytium. The preservation number of the strain is CCTCC M 206118. The invention generates Huperzine A analogous compound through the strain liquid fermentation of the endophytic fungi from huperzia serrata, and is significant micro organism for searching the Huperzine A new resource of the active component for curing the presenile dementia.

A process for producing a saccharified solution, by which xylose can be produced at a high yield from lignocellulosic biomass, is provided. The saccharification is carried out by adding a saccharifying enzyme to a pretreated material for saccharification of the lignocellulosic biomass. As the saccharifying enzyme is added a mixture of a first saccharifying enzyme originated from one or more microorganisms selected from the group consisting of fungi of the genus Acremonium, the genus Trichoderma, the genus Penicillium, the genus Aspergillus and the genus Thermoascus, and eubacteria of the genus Clostridium and the genus Bacillus, and a second saccharifying enzyme composed of β-xylosidase originated from Thermotoga maritima.

The object of the present invention is to provide a bacterial strain for preventing and treating aphids, that is, a strain of Acremonium sp. from marine bottom mud, and the preservation number is: CGMCC NO.11658. The mfn1 bacterial strain screened by the present invention is used to prevent and control aphids, and can also be used to prepare products with the function of preventing and controlling aphids. The mfn1 bacterial strain with biological activity on tobacco aphid obtained by the present invention can be applied to the prevention and treatment of tobacco aphid, and the biological measurement of aphid by micro-drop method shows that the lethality of secondary metabolites in its fermentation liquid to aphid Up to 97.78%. After chemical analysis and structural identification by GC / MS, the secondary metabolites included 7 main compounds, including 3 peptide compounds, 2 ester compounds, alkaloid accumulation compounds, and hydrazine compounds, 1 each.

The invention discloses a production method of a feed additive "acremonium acremonium culture". This production method improves the production process of Acremonium acremonium culture through the research on the growth characteristics of Acremonium acremonium, and shortens the production cycle of Acremonium acremonium culture from the original 11 to 15 days to 5 days after improvement. , greatly reducing the production cost of Acremonium acremonium culture, which is of great significance to the market promotion of this high-end feed additive; at the same time, it greatly reduces the energy consumption of water, electricity and electricity in the production process. The production process of "Acremonium acremonium culture" in the present invention mainly includes "liquid strain fermentation" and "solid fermentation". The results of animal experiments show that the feed additive can significantly improve animal immunity, lower feed-to-meat ratio, and improve meat quality. The method for producing the "acremonium acremonium culture" feed additive has the advantages of low cost, short production cycle, controllable quality, good application effect and the like.

The present invention relates to fungi of Acremonium spp, wherein said fungi are purified or isolated from plants of the Brachiaria-Urochloa complex and wherein, when said fungi are inoculated into a plant, said plant has improved resistance to diseases and / or pests relative to an uninocualated control plant. The present invention also relates to plants inoculated with such fungi, products produced by the fungi and related genes, proteins and methods.

The invention discloses a rapid seedling-raising method capable of promoting high germination rate of pseudo-ginseng by utilizing acremonium strictum. The rapid seedling-raising method comprises the following steps: acremonium strictum strain culturing, seed treatment, sowing, breeding management, and germination and transplanting. According to the invention, compared with traditional irrigation of seeds with water, the germination rate of pseudo-ginseng seeds is increased by 20% or more, and can reach up to 90% or more; the time of seedling raising can be shortened by 10 to 20 days; meanwhile, the cultured seedlings are strong and neat and grow rapidly, and the time of seedling raising can be saved, so great significance on plantation of the pseudo-ginseng is obtained.

Provided is acremonium implicatum CQBBW8. The preservation number is CGMCC No.11440. The sequence homology between the rDNA-ITS sequence of the acremonium implicatum and the isolate LR2 of the acremonium implicatum reaches up to 98%. The acremonium implicatum CQBBW8 which is separated from citrus red mite bodies is good in production character and fast in growth, and the colony diameter can reach 5.083 cm after culture is performed for 15 days. Meanwhile, the killing activity on various pests is high, the pest killing effect is good, and the death rate of third instar larva of papilio xuthus linnaeus reaches up to 100%, the death rate of aphids reaches up to 100%, and the death rate of citrus red mites reaches up to 100% when the acremonium implicatum with 10<6> conidia / mL is used for killing the pests. An insecticidal fungus preparation produced through the acremonium implicatum effectively controls the colony quantity of various pests.
