Medium is an artificially formulated nutrient for the growth and maintenance of microorganisms, plants and animal tissues. It generally contains carbohydrates, nitrogen-containing substances, inorganic salts (including trace elements), vitamins and Water . Some culture media also contain antibiotics and pigments, used for the cultivation and identification of single microorganisms. The fermentation medium is for the growth, propagation and synthesis of bacteria. It must not only enable the seeds to grow rapidly after inoculation to reach a certain hypha concentration, but also enable the grown bacteria to quickly synthesize the desired products. Therefore, the composition of the fermentation medium should be rich and complete, and the carbon and nitrogen sources should pay attention to the combination of fast-acting and delayed-acting, less fast-acting nutrition, and more delayed-acting nutrition; also consider the appropriate carbon-to-nitrogen ratio and add buffer to stabilize pH value; and also the growth factors required for bacterial growth and the elements, precursors and accelerators required for product synthesis. In addition to the elements and compounds necessary for bacterial growth, there are also specific elements, precursors and accelerators required for the product.

Jia Teng Glassware can be used for Milk , which is very important in our daily life. In a sense, it means nutrition and health to us. Our products are made of borosilicate glass and it is mainly exported to the United States and many European countries. With high quality and nice looking, it got good feedback from the world market. Borosilicate glass is a strong heat-resistant glass traditionally used to make scientific lab glass. It is simply a different type of glass that is resistant to temperature swings and scratching. It is dishwasher and microwave safe, also free for BPA, Lead and Mercury.
