What is the ratio of carbide carbon to nitrogen?

Channel News: Carbon-nitrogen ratio is a value that indicates the value of carbon in the medium divided by nitrogen, if the carbon-nitrogen ratio (C/N) is 20, which means that the content of carbon in the organic fertilizer is 20 times the content of nitrogen, of course, the carbon-nitrogen ratio can only indicate the ratio of carbon and nitrogen in the medium, and does not represent nutrient content.
attention to the concentration ratio of nutrients and C/N for example: sugar content should be suitable for microbial growth in order to be good, too much sugar inhibits microbial growth.
general microbial suitability C/N is 25:1 (element C/N ratio, also refers to the ratio of reduced sugar content in the medium to crude protein content).
Nutrient concentration and ratio of appropriate nutrient concentration in the medium can grow well, nutrient concentration is too low to meet the normal growth needs of microorganisms, concentration is too high may inhibit the growth of microorganisms, such as high concentration of sugar, inorganic salts, heavy metal ions, etc. not only can not maintain and promote the growth of microorganisms, but play a role in suppressing bacteria or sterilization.
addition, the concentration ratio between nutrients in the medium also directly affects the growth and reproduction of microorganisms and/or the formation and accumulation of metabolites, of which the carbon-nitrogen ratio (C/N) has a greater impact.
, the carbon-nitrogen ratio refers to the ratio of carbon to nitrogen in a medium, and sometimes to the ratio of reduced sugar to crude protein in a medium.
For example, in the process of using microbial fermentation to produce glutamate, when the media carbon-nitrogen ratio is 4/l, the bacteria multiply in large numbers and glutamate accumulate less, and when the media carbon-nitrogen ratio is 3/l, the reproduction of the bacteria is inhibited and glutamate production increases significantly.
, in the production of antibiotic fermentation, the coordination of bacteria growth and antibiotic synthesis can be controlled by controlling the ratio of quick-acting nitrogen (or carbon) sources in the medium to late-acting nitrogen (or carbon) sources.
