FM601 is a nutrient-rich yeast extract product that is designed to enhance the growth and stability of live lactic acid bacteria during fermentation. It contains high levels of glutathione, an important antioxidant that helps to maintain the viability of bacterial cells. With its balanced distribution of polypeptides and other essential nutrients, FM601 is an ideal choice for optimizing fermentation solutions and improving production capacity.

Yeast extract contains not only polypeptides, amino acids, and nucleotides, but also minerals, making it an important nutritional source for microbial growth and widely applicable in the production of industrial fermentation products.

Lactic acid bacteria are facultative anaerobes with poor oxygen tolerance, weak protein degradation ability, poor nucleic acid synthesis ability. Angel Yeast company has conducted research on the nutritional absorption ability and metabolic defects of lactic acid bacteria, optimized the distribution of polypeptides and nutrients such as glutathione through autolysis technology, and developed extract FM601 suitable for facultative anaerobic lactic acid bacteria. This product can increase the biomass and viable cell count of lactic acid bacteria and improve the stability of bacterial cells.

FM601 is widely used for the cultivation of facultative anaerobic lactic acid bacteria, such as Lactobacillus rhamnosus and Bifidobacterium species. It is specifically designed for difficult-to-culture microorganisms, and can increase biomass and viable cell count, thereby improving industrial production capacity.

Product Features:

◉ Balanced distribution of peptide molecular weight

◉ Rich in amino acids, peptides, glutathione, trehalose, vitamins, etc.

Product Benefits:

◉ Enhance biomass

◉ Maintain cell vitality

◉ Delay cell death

Compared to the control group without glutathione, yeast extract FM601 fermented L. rhamnosus with shorter cell morphology. Glutathione may be the main factor affecting the cell shape of lactobacillus. By optimizing the amount of glutathione added, the morphology of L. rhamnosus can be significantly changed.

In the stabilization period of L. rhamnosus, the biomass of FM601 group was 10% higher than that of the control group, the viable count of FM601 fermented L. rhamnosus increased by 20%, and the 24h viable count was 70% higher than that of the control group. FM601 increased the biomass of the bacteria, improved the viable count of the fermentation broth, and delayed the decay of L. rhamnosus.
