The present application relates to a strain of Inhernia Bacillus and its application in ramie degumming, the strain is preserved in Guangdong Microbial Culture Collection Center on September 15, 2025, and the preservation number is GDMCC NO: 66966. When the strain is applied to ramie degumming, the degumming reaction can be carried out at a higher temperature, the degumming efficiency of ramie is effectively improved, the fiber is not damaged, the quality of the fiber is improved, and the strain has high application value in ramie degumming.

The present application relates to a kind of coal slime collector preparation method using kitchen waste oil, comprising the kitchen waste oil after being pretreated with water, emulsifier is mixed, as carbon source configuration first culture medium, Bacillus and Rhodococcus species are inoculated in it and carry out aerobic fermentation, obtain refined oil, and as carbon source configuration second culture medium, Candida species are inoculated in it and carry out aerobic fermentation, obtain mixed fatty acid, and as carbon source configuration third culture medium, Yarrowia species are inoculated in it and carry out micro-aerobic fermentation, obtain alkane mixture;Emulsified oil and / or refined oil are as carbon source configuration fourth culture medium, Pseudomonas species are inoculated in it and carry out aerobic fermentation, obtain rhamnolipid;Alkane mixture is mixed with rhamnolipid, obtain coal slime collector.The present application develops a new type of green, good coal slime collector by constructing multistage series biological transformation process.

The application discloses collagen tripeptide and a preparation method and application thereof, and belongs to the technical field of bioengineering. The preparation method comprises the following steps: obtaining bacillus velezensis with high collagenase yield through separation and identification, the bacillus velezensis belongs to probiotics, and high-activity collagenase is obtained through fermentation culture and purification; taking shark cartilage or blue fish skin as raw materials, and obtaining collagen tripeptide through the following steps of combined enzymolysis of alkaline protease and collagenase after pretreatment, inactivation, centrifugal separation and freeze-drying. The collagen tripeptide prepared by the application has a molecular weight of less than 500 Dalton, contains active components such as GHK tripeptide, is easy to absorb and has high safety, and can be used for preparing antioxidant products, anti-inflammatory products, memory-enhancing products or immunity-enhancing products. The application solves the problems of unsafe collagenase source and low collagen tripeptide preparation efficiency, and has a good industrial application prospect.

The invention relates to a method for obtaining a gramicidin S extract from spore-forming Bacillus belonging to the genus Aneurinibacillus, characterised by comprising a solid-liquid extraction step using a solvent selected from the group comprising lactic acid, acetic acid, a biosurfactant extract obtained from corn steep liquors, or combinations thereof, at a temperature equal to or less than 40 °C. The invention also relates to the use of the gramicidin S extract obtained as an antimicrobial agent in the cosmetic and agrochemical industries, and as an antibiotic in the pharmaceutical industry.

The present invention relates to an aqueous composition for reduction of malodour, particularly secondary malodour, or dank malodour from surfaces. It is especially useful for malodour reduction from soft surfaces like fabric which may be sprayed with the aqueous composition and allowed to remain thereon. Optionally such fabric may thereafter be laundered using any known laundering process to deliver enhanced malodour reduction benefits. This is achieved through use of an aqueous surfactant containing composition that comprises a bacillus bacterial spore along with select alkane diol.
