The present invention relates to modified filamentous fungal organisms having improved activity profiles with respect to the conversion of complex carbohydrates into simple sugars from cellulosic materials, including fungal organisms belonging to a genus selected from the group consisting of: Chrysosporium, Thielavia, Talaromyces, Thermomyces, Thermoascus, Neurospora, Aureobasidium, Filibasidium, Piromyces, Corynascus, Cryplococcus, Acremonium, Tolypocladium, Scytalidium, Schizophyllum, Sporotrichum, Penicillium, Gibberella, Myceliophthora, Mucor, Aspergillus, Fusarium, Humicola, Trichoderma, and Talaromyces, plus anamorphs and teleomorphs thereof. Filamentous fungal organisms having improved activity profiles are obtained by modifying genes encoding enzymes involved in the production of cellobionolactone, cellobionic acid, gluconolactone, gluconic acid, and related products, by a variety of mutagenic methods, resulting in nucleotide substitutions, insertions, and deletions, increasing the level of saccharification in enzyme mixtures obtained from the modified organisms.

The invention provides an acremonium strictum strain BH-0531 separated from a Bohai Bay water area and screening and an application thereof. The strain is collected in the China General Microbiological Culture Collection Center with the collection number of CGMCC No.5445. The strain is separated from a sample of bottom layer seawater in the Bohai Bay, and is obtained by screening and identifying.The BH-0531 strain separated and screened in the invention belongs to acremonium strictum (originally called cephalosporium), has the characteristics of low growing temperatures of marine microorganisms and growth under high-salt conditions, and has the capability of producing nematicidal active metabolic products; produced nematicidal substances have high thermal stability and water solubility; the nematicidal activity can be over 94 percent under experimental conditions; and the acremonium strictum strain BH-0531 can be applied to fermentation production of bioactive substances such as nematicides, antibiotics and the like.

The invention provides a method for fermentation production of cephalosporin C. The method comprises a step a of taking cephalosporins acremonium, and preparing primary seeds and secondary seeds; a step b of taking the secondary seeds prepared through the step a, inoculating the secondary seeds to a cephalosporins acremonium fermentation medium to perform fermentation, performing discharging after fermentation for 50-115 h, and re-cultivating the discharged liquid; a step c of taking the fermentation broth and the discharged culture liquid obtained through the step b, performing separation and purification, and obtaining cephalosporin C. According to the fermentation method, the single batch yield of cephalosporin C can be remarkably improved, the cost is greatly reduced, and the industrial application prospect is good.

The invention relates to the technical field of biological pesticides, in particular to a biocontrol preparation with a nematicidal function and a preparation method of the biocontrol preparation withthe nematicidal function. The biocontrol preparation with the nematicidal function provided by the invention comprises the following main components in parts by weight: 3 to 7 parts of plant ash, 8 to 18 parts of borax, and 5 to 10 parts of lyophilized powder of an acremonium yunnanensis culture solution. The invention further provides the preparation method of the biocontrol preparation, comprising the following steps: collecting the culture solution after culturing the acremonium yunnanensis, freeze-drying and adding the plant ash, borax and sawdust. The active component in the biocontrol preparation provided by the invention is the lyophilized powder of the acremonium yunnanensis culture solution, and has a very good root-knot nematode killing effect.

The invention provides a piglet mixed feed additive for improving feed intake and an application thereof. The additive comprises the following components in parts by weight: 5-8 parts of Bacillus subtilis, 2-4 parts of Lactobacillus acidophilus, 30-40 parts of Acremonium acremonium culture, 5-8 parts of vitamin C, 2-4 parts of lysozyme, 4-6 parts of calcium formate, 2-4 parts of glucose oxidase, and 40-50 parts of milk powder. The piglet mixed feed additive is mainly directed to the post-weaning stress of piglets, and ensures the safety, effectiveness and stability of the feed additive compounding through clear formula ratio and the action mechanism of components, and significantly improves the feed intake of the nursery pigs, and the effect is stable and reliable; the piglet mixed feed additive has a strong target for the weaning stress period of the piglets, is stable and effective for the suckling piglets to pass from a lactation period to a feed feeding stage, significantly improves the growth performance of the nursery pigs, and improves the economic benefits of the farmers.

The invention relates to acremonium, a culturing method of the acremonium and an application of the acremonium to preparation of original spore powder of a meloidogyne pesticide. Currently, a pollution-free sustainable control method with biological control as the core is used as a main direction of control of meloidogyne diseases. According to the application, the acremonium JXC224 is selected and injected into a liquid fermentation medium, a seed solution is obtained and injected into a solid medium with the inoculation amount of 10% by mass ratio, solid yeast is prepared and dried till the moisture content is lower than 15%, the solid yeast is ground by a dust-collection grinder and screened on a vibrating screen, and the acremonium JXC224 original spore powder is obtained and used as the meloidogyne pesticide. The microbial pesticide original spore powder containing acremonium spores playing a role in infection, killing and biological control of meloidogyne is provided and applicable to the biological control of the serious meloidogyne diseases in vegetable and fruit planting processes of agricultural facilities, and the control effect on the meloidogyne of peppers, tomatoes, cucumbers and the like can exceed 93%.
