The invention belongs to the technical field of biology, and particularly relates to a heat-resistant element newly derived from Thermus thermophilus and application of the heat-resistant element. The heat-resistant gene is derived from Thermus thermophilus, is connected with a promoter and is transformed into Corynebacterium glutamicum. Experimental results show that after the corynebacterium glutamicum is cultured at the high temperature of 42 DEG C for 24 hours, the OD600 of the corynebacterium glutamicum carrying the heat-resistant elements and plasmids is obviously higher than that of a control strain ATCC 13032, which indicates that the corynebacterium glutamicum has obviously better growth capability under the high-temperature condition than that of a starting strain, and the effectiveness of the heat-resistant elements in the aspect of improving the heat resistance of the strains is verified. The method is of great significance to improvement of the thermal stability of the corynebacterium glutamicum and application prospects of the corynebacterium glutamicum in industrial production.

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 present invention belongs to the field of food technology, and specifically relates to a small molecule peptide prebiotic probiotic powder and a preparation method thereof. After mixing probiotics, part of fish collagen peptides and stachyose are taken to embed the probiotics, and after freeze-drying and crushing, porous composite probiotics are obtained; inulin and the remaining fish collagen peptides and stachyose are taken to form a gel with the composite probiotics, and lactitol is used for sealing. The small molecule peptide prebiotic probiotic powder provided by the present invention contains fish collagen peptides and stachyose, inulin and lactitol that are beneficial to the human body, and can not only improve the growth activity of bacterial powder as a prebiotic, but also form freeze-drying protection support on the surface of bacterial powder, and can also increase the isolation ability of bacterial bodies from the external environment during storage and consumption, so as to achieve full utilization of materials and reduce the probability of introduction of impurities and miscellaneous bacteria.

The invention provides an environment parameter adaptive optimization method for edible mushroom breeding. The method comprises the following steps: S1, constructing an edible mushroom growth cycle standard database; s2, collecting multi-dimensional environmental parameters of the edible mushrooms; s3, constructing a growth cycle prediction model, inputting multi-dimensional environmental parameters, and predicting the growth cycle of the edible fungi; the growth cycle prediction model is used for constructing a daily growth variable function by taking matrix overall weight and matrix pressure in multi-dimensional environmental parameters as core parameters, accumulating daily growth variables to obtain a comprehensive growth index, and finally predicting the current growth stage of the edible mushrooms according to threshold intervals of different growth stages corresponding to the comprehensive growth index; s4, inputting a predicted edible mushroom growth cycle to the standard database in the step 1 to obtain standard environment parameters and self-adaptive regulation and control environment parameters; and according to the predicted growth cycle, obtaining the standard environmental parameters of the edible mushrooms in the corresponding stages from the standard database, and correspondingly regulating and controlling the real-time environmental parameters of the edible mushrooms.
