  • Selection of Nitrogen Source in Cultivation of Lactic Acid Bacteria

    Selection of Nitrogen Source in Cultivation of Lactic Acid Bacteria

    Different lactic acid bacteria have different nutritional characteristics requirements. According to comprehensive application tests and customer feedback, using Angel's yeast extract FM985, FM502 and related yeast extracts solely or together can meet the growth needs of lactic acid bacteria with obtaining higher biomass and longer shelf life.

  • Essential knowledge for fermentation industry:what is fermentation engineering?

    Essential knowledge for fermentation industry:what is fermentation engineering?

    Microbial fermentation engineering refers to the use of modern engineering techniques to make use of certain specific functions of microorganisms to produce useful products for human, or a new technology that directly applies microorganisms to industrial production processes. The content of fermentation engineering includes the selection of strains, the preparation of culture medium, sterilization, expansion of culture and inoculation, fermentation process and product separation and purification. Fermentation engineering plays a key role in the industrialization of biotechnology.

  • Essential knowledge for fermentation industry:what is culture media?

    Essential knowledge for fermentation industry:what is culture media?

    Microbial culture medium usually refers to artificially formulated nutrient substrate suitable for microbial growth and reproduction, or accumulation of metabolites. Broadly speaking, any medium or material that supports the growth and reproduction of microorganisms can be used as a culture medium for microorganisms. A proper medium formula has a great influence on the yield and quality of fermented products.

  • Essential knowledge for fermentation industry - what is peptone?

    Essential knowledge for fermentation industry - what is peptone?

    Peptone, a protein decomposition product, is made by incomplete hydrolysis process of the protein originated from beef, casein, milk powder, gelatin, soy protein, silk protein, fibrin, etc.

  • Essential knowledge for fermentation industry:what is yeast extract?

    Essential knowledge for fermentation industry:what is yeast extract?

    Yeast extract, derived from yeast, utilizes biotechnology to degrade the protein and nucleic acid in the cell under a specific environment, and then prepared as a soluble nutrient source through downstream processing operations such as centrifugation, concentration, filtration, etc.

  • Organic nitrogen source and regulation of amino acid fermentation process

    Organic nitrogen source and regulation of amino acid fermentation process

    How the organic nitrogen source plays a regulatory role in the metabolic flow of amino acid fermentation and how it is regulated have always been a key topic in the amino acid fermentation industry as well as important practical significance for guiding fermentation production.

  • Yeast-based organic nitrogen source and its application in fermentation industry

    Yeast-based organic nitrogen source and its application in fermentation industry

    For a long time, the development of yeast-based organic nitrogen sources has been an important aspect of the development and utilization of yeast. This article reviews the types and characteristics of yeast-based organic nitrogen sources as well as their application progress in fermentation industry. Yeast-based organic nitrogen sources are rich in proteins, peptides, amino acids, vitamins and minerals. They can provide rich nutrients for microbial fermentation of both seed culture and fermentation culture stage, thus it is widely used in various fermentation industries.
