The invention discloses application of mortierella 2K4 as a biocontrol bacterium for poplar anthracnose, and belongs to the technical field of microbial pesticides. A plate confrontation experiment proves that the strain has a remarkable antagonistic effect on poplar anthracnose pathogenic bacteria colletotrichum gloeosporioides, and the bacteriostasis rate reaches 50.9%. The fermentation filtrate also shows a concentration-dependent antibacterial effect, and the antibacterial rate of 50% concentration is 45.50%. In-vitro leaf and pot experiments further prove that the scab diameter and disease index of the poplar anthracnose can be effectively reduced by applying the strain, and the prevention and treatment effect exceeds 59.45%. The invention provides an efficient and environment-friendly biocontrol bacterium resource for green prevention and control of poplar anthracnose and an application method of the biocontrol bacterium resource.

The present invention provides a method of producing a composition capable of producing a food-like aroma and / or flavour when heated, comprising a) disrupting a Mortierella spp. biomass comprising phospholipids; b) fractionating the disrupted biomass and collecting the supernatant therefrom; and c) combining the supernatant with: (i) one or more sugars, sugar alcohols, sugar acids, or sugar derivatives; and (ii) one or more amino acids or derivatives or salts thereof, or a compound comprising an amino group (e.g. thiamine). The present invention further provides compositions comprising a supernatant of a fractionated, disrupted Mortierella spp. biomass comprising phospholipids and methods of producing food-like aromas and / or flavours.

The invention relates to a microbial oil composition as well as a preparation method and application thereof, the composition is prepared by fermentation of a specific Mortierella strain, and the composition comprises the following components in percentage by weight of total fatty acid: less than or equal to 0.55 wt% of trans-fatty acid, less than or equal to 0.05 wt% of fatty acid, less than or equal to 0.05 wt% of fatty acid, and less than or equal to 0.05 wt% of fatty acid; the content of saturated fatty acid with carbon chain length not less than 16 is not more than 23wt%; n-3 unsaturated fatty acid is less than or equal to 3.0 wt%; n-6 unsaturated fatty acid; wherein the ratio of arachidonic acid to n-6 unsaturated fatty acid is greater than or equal to 75 wt%. The invention also provides a fermentation process by controlling the carbon source and dynamically adjusting the ventilation volume. The composition effectively reduces the content of saturated ultra-long chain fatty acid, relieves the metabolic burden of infants, is high in safety, ensures the core nutritional value of ARA, and is suitable for the fields of infant formula food, medicine, health food and the like.

The invention provides a microbial fertilizer for preventing and treating panax notoginseng root rot, and relates to the technical field of microbial fertilizers.The microbial fertilizer comprises A-type quick-acting particles and B-type long-acting dormancy particles, the A-type particles take biochar as a carrier to bear a specific microbial complex, the B-type particles take biochar bearing the microbial complex as a core, a biodegradable film is coated outside the B-type particles, and the B-type particles are coated outside the biochar bearing the microbial complex. The microbial complex is composed of burkholderia, Savitz yeast, mortierella and streptomyces medicaginis, and the fertilizer is combined with deep ploughing preset basal application and targeted activation application methods, so that full-profile long-acting prevention and control of panax notoginseng root rot can be realized, and soil micro-ecology can be restored.

This invention discloses a method for preparing and applying chestnut organic fertilizer made from forest stand residues. It belongs to the field of organic fertilizer preparation technology. The method first involves crushing chestnut fruit buds, dead branches, and other residues. A specific ratio of compound fermentation agent is added, the carbon-nitrogen ratio and pH value are adjusted, and wood vinegar and brown sugar are used. Under controlled humidity and temperature conditions, composting fermentation is carried out to obtain highly decomposed organic matter. Subsequently, a specific probiotic fungus agent such as Mortierella is inoculated into this organic matter, and it is covered with forest understory soil rich in probiotic fungi for secondary fermentation, ultimately producing a chestnut-specific organic fertilizer. This product can significantly improve soil fertility and chestnut yield. For application, it is applied deeply near the drip line of chestnut trees in mid-to-late December each year, at a rate of 15-20 kg / tree. This invention successfully achieves the efficient resource utilization of chestnut residues, turning waste into treasure, and possessing both ecological and economic benefits.
