The statement about traditional fermentation technology is wrong.

Knowledge expansion of traditional fermentation technology;

Traditional fermentation technology: people are familiar with the production of beer, fruit wine and industrial alcohol by yeast fermentation, cheese and yogurt by lactic acid bacteria fermentation, and penicillin by fungi on a large scale.

Modern fermentation technology has made great progress, and has entered the stage of modern fermentation engineering, which can manually control and transform microorganisms to make them produce products for human beings. For example, genetic engineering is used to purposefully transform the original strain and improve its yield; Using microbial fermentation to produce drugs, such as human insulin, interferon and growth hormone.
