This invention discloses a strain of *Bacillus spp.* from soil, which was deposited at the Guangdong Provincial Center for Microbial Culture Collection on September 15, 2025, with accession number GDMCC NO.66967. This strain exhibits good heat resistance, and the mannanase it produces maintains stable enzyme activity under high-temperature conditions. Compared to hydrolases under ordinary conditions, it has greater plasticity and is suitable for the production of products or by-products in multiple fields. In addition, this strain can also be applied to the degumming process of hemp fibers, demonstrating excellent degumming effects on hemp fibers.

The application discloses a ramie bio-enzyme steaming pile degumming method and belongs to the technical field of ramie fiber degumming process methods. The method comprises the following steps: immersing pressed ramie raw fibers into a broken wall pretreatment liquid, taking out the ramie raw fibers for steaming pile treatment, adding the ramie raw fibers into a pectinase degumming liquid after knocking and washing, taking out the ramie raw fibers for steaming pile treatment, then adding the ramie raw fibers into a chlorine-free bleaching liquid for bleaching, washing, oiling and drying. The method solves the problems of low utilization rate and high degumming cost caused by a large bath during treatment through steaming pile treatment. Compared with a traditional chemical degumming process, the method has a shorter time consumption, lower nitrogen and phosphorus content and COD value in waste liquid, and the obtained fine dry fibers are finer, softer and stronger, the surface fluff of spun ramie cloth is less, and the itching feeling after wearing is reduced.

The invention discloses an enzymatic biological degumming method of industrial hemp fiber, and relates to the field of degumming of industrial hemp fiber, according to the enzymatic biological degumming method of industrial hemp fiber, MnP enzyme is produced by white rot fungi, veratryl alcohol is added as a mediator, and the MnP enzyme and the veratryl alcohol form an oxidation-reduction cycle; and colloid components such as lignin-hemicellulose compounds in the raw industrial hemp can be efficiently degraded. Compared with the prior art, the residual gum rate is greatly reduced to 1.2%-1.8% and is reduced by 60%-85% compared with a contrast, the degumming rate is larger than or equal to 98%, and the degumming effect is quite remarkable. Meanwhile, ultrasonic pretreatment destroys a wax coat on the surface of the fiber and promotes enzyme liquid permeation, and mild biological catalysis conditions are combined, so that damage to the fiber is reduced to the maximum extent. Due to the series of advantages, the degummed industrial hemp fibers are excellent in key indexes such as strength and whiteness, and completely meet the quality requirements of high-end textile products.
