The invention relates to a lactic acid bacteria composition and an application thereof in a low-temperature liquid biological feed, in particular to a lactic acid bacteria complex microbial inoculant suitable for a low-temperature environment (15-25 DEG C) and a fermentation process of the lactic acid bacteria complex microbial inoculant. The combination comprises pediococcus pentosaceus WP101 (the preservation number is CCTCC NO: M 20241055) and lactobacillus plantarum PC01 (the preservation number is CCTCC NO: M2022106), and the viable count of the combination is 25 million cfu / g feed according to the proportion of 1: 1. By optimizing the synergistic effect of strains and fermentation conditions, efficient fermentation in a low-temperature environment is realized, the content of lactic acid in the feed is remarkably increased, and growth of harmful microorganisms is inhibited. Animal experiments show that the fermented feed can reduce the diarrhea rate of piglets by 45.5% (Plt; 0.05), improve the daily gain of fattening pigs in the later period and the feed conversion rate, and reduce the loss of dry matters at the same time. The problem of energy consumption caused by the fact that traditional medium-temperature fermentation depends on heating and heat preservation is solved, technical support is provided for large-scale low-temperature liquid biological feed production, and economic and environmental benefits are achieved.

This utility model discloses an intelligent constant temperature and humidity incubator for edible fungi, belonging to the technical field of edible fungi incubators. It includes a cabinet with elongated air vents on its inner sidewall and a flow equalization mechanism on the outer back of the cabinet. The flow equalization mechanism includes an airflow mixing chamber sealed to the back of the cabinet. A vortex hood is fixed to the side of the airflow mixing chamber that contacts the cabinet, and a centrifugal impeller is rotatably mounted inside the vortex hood via a shaft. By setting an airflow control mechanism on the incubator, the treated airflow is buffered in the airflow mixing chamber. Combined with a flow equalization device consisting of a drive motor, transmission components, vortex hood, and centrifugal impeller, the airflow is further accelerated and distributed, allowing it to enter the shelf layers of the incubator with a wider coverage area and stronger power. This ensures that the airflow flows fully around the edible fungi container, guaranteeing efficient growth of the fungi under constant temperature and humidity conditions.
