This invention discloses a fermentation method for improving the flavor and stability of old dough, belonging to the field of food technology. The method includes: mixing activated *Candida cruzi*, *Lactobacillus brevis*, *Hansenula polymorpha*, *Yarrowia lipolytica*, and *Saccharomyces cerevisiae* in a specific ratio to obtain a compound bacterial solution; and fermenting coarse grains with this compound bacterial solution to obtain coarse grain steamed buns. This invention employs the synergistic fermentation of five specific bacterial strains. *Lactobacillus brevis* and *Candida cruzi* synergistically optimize the rheological properties of the dough, *Hansenula polymorpha* and *Saccharomyces cerevisiae* synergistically produce rich aroma compounds, and *Yarrowia lipolytica* secretes phytase and cellolytic enzymes to lower the glycemic index. The coarse grain steamed buns prepared by this invention contain 55-65 flavor compounds, and the glycemic index is estimated to be reduced to 48-56, achieving a stable and controllable fermentation process, a low-GI product, and a rich flavor.

This application relates to the field of biotechnology, and particularly to primer pairs, primer-probe compositions, PCR premixes, kits, and methods for detecting multiple respiratory pathogens. Nucleic acid sequences are shown in primer pairs as indicated by SEQ ID NO: 1-2, 4-5, 7-8, 10-11, 13-14, 16-17, 19-20, 22-23, 25-26, 28-29, 31-32, 34-35, 37-38, and 40-41. For target respiratory pathogens, this application designs specific amplification primer pairs, paired with suitable probes, enabling the simultaneous detection of eight targets. Furthermore, the detection process avoids interference from heme, trimethoprim, sulfamethoxazole, amphotericin B, itraconazole, fluconazole, azithromycin, adrenaline, and lidocaine hydrochloride in the test sample. It exhibits good anti-interference properties and shows no cross-reactivity with *Rhodococcus equi*, *Candida tropicalis*, and *Candida krusei*.

This application belongs to the field of microbial technology, specifically disclosing the application of *Lactobacillus fermentum* BLF03 in anti-Candida activity. *Lactobacillus fermentum* BLF03 was deposited on November 6, 2025, at the China General Microbiological Culture Collection Center (CGMCC) with accession number CGMCC No. 36521. This application proposes a *Lactobacillus fermentum* BLF03 strain resistant to *Candida albicans* and *Candida krusei*, which can significantly inhibit the growth, reproduction, and hyphal transformation of *Candida albicans* and *Candida krusei* at the in vivo level, alleviate Candida-induced infection symptoms, reduce the expression level of the inflammatory marker procalcitonin (PCT) after Candida infection, improve the inflammatory stress response induced by infection, and has a significant protective effect against tissue damage caused by Candida invasion. It also has targeted preventive and adjunctive therapeutic effects on Candida infections in the urogenital tract and other sites, providing a new, safe, and highly effective strain for anti-Candida products.

The application discloses a heavy Zanthoxylum bungeanum essential oil component with antibacterial activity and a preparation method thereof. The Zanthoxylum bungeanum essential oil is deeply researched, and the Zanthoxylum bungeanum essential oil is separated into a light Zanthoxylum bungeanum essential oil component and the heavy Zanthoxylum bungeanum essential oil component through a molecular distillation instrument. The antibacterial and antifungal experimental results show that the heavy Zanthoxylum bungeanum essential oil component obtained through distillation refining has better bactericidal activity on Klebsiella pneumoniae, methicillin-resistant Staphylococcus aureus, Staphylococcus aureus and corynebacterium striatum compared with the Zanthoxylum bungeanum essential oil and the light Zanthoxylum bungeanum essential oil component, and has better bactericidal activity on Candida tropicalis, Candida krusei, Candida glabrata and white Candida, and a good technical effect is achieved.

The present invention relates to new active agents for use in the treatment of diseases caused by the yeast strains C. albicans ATCC 10231, C. krusei ATCC 6258, and C. tropicalis Y-12968.

The invention relates to an essence preparation method, in particular to a method for extracting high-quality cigarette essential oil with assistance of fungus fermentation, and belongs to the IPC (International Patent Classification) C11B9 range. The method comprises the following steps: crushing plant raw materials, carrying out anaerobic fermentation by adopting candida krusei CICC 31796 and lactobacillus delbrueckii subsp. Lactis GDMCC NO.1. 3694 as zymophyte, then filtering, adding ethyl acetate for extraction, removing water, and concentrating to remove ethyl acetate, so as to obtain the essential oil. The essential oil prepared in a fermentation extraction mode is high in fragrance intensity and has a good application prospect in cigarettes; in addition, an essence finished product prepared from the essential oil is excellent in performance and high in stability.
