Culture medium for streptococcus pneumoniae

Abstract

The invention provides a culture medium for streptococcus pneumoniae. The culture medium for streptococcus pneumoniae is prepared from, by weight, 8 parts of starch, 6 parts of saccharose, 2 parts of potato, 1 part of nicotinic acid, 1 part of lycium barbarum leaves, 1 part of amethyst and 1 part of radix ophiopogonis. On this basis, a specific amount of cysteine, casein or glucose can also be added. By adding certain traditional Chinese medicinal materials based on common materials of culture media, a remarkable culture effect is realized unexpectedly. The culture medium is especially suitable for streptococcus pneumoniae culture and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a culture medium for Streptococcus pneumoniae. Background technique [0002] Streptococcus pneumoniae was first isolated from patient sputum in France and the United States by Louis Pasteur and G.M.Sternberg in 1881, respectively. It is Gram-positive, and the bacteria are like spearheads, diplococci arranged in pairs or in short chains, and some virulent strains have a capsule with a chemical composition of polysaccharides. 5% to 10% of normal people carry this bacterium in the upper respiratory tract, and the virulent strain is an important pathogenic bacterium that causes human diseases. The bacterial strain has certain applications in the field of biotechnology, but the growth rate of Streptococcus pneumoniae is relatively slow in the commonly used culture medium, and at the same time, it is prone to bacterial contamination.
