Fermentation broth pretreatment is an important step in the extraction of biochemical substances from microbial fermentation broth. The aim is not only to separate cells, cells and other suspended particles, but also to remove some soluble impurities and change the properties of the filtrate to facilitate subsequent steps.The method of pretreatment depends entirely on the properties of the separable substance, such as its stability to PH and heat, whether it is protein or non-protein, the mass a

With global warming, population growth and rising food consumption, the food industry is facing unprecedented challenges.

The combination of synthetic biology and food science has given rise to new synthetic foods that have gained a high level of attention in addressing these issues. However, at the same time, they may also pose potential risks to human health.

This paper briefly introduces four types of synthetic biofoods: plant-based foods, cultured meats, fermented foods, and microalgae

This paper, "Empowering Biomedical Discovery with AI Agents," was jointly written by researchers from Harvard Medical School, Massachusetts Institute of Technology, Imperial College of Technology, and other institutions. It explores how artificial intelligence (AI) agents can promote the development of biomedical research through skeptical learning and reasoning, combined with machine learning tools and experimental platforms.

Most fermentation industries rely on purebred cultivation, and the production process can only have producing bacteria, with no other bacteria allowed.

To ensure pure fermentation, the culture medium, air system, feed system, fermentation tank, and pipeline system should be sterilized before inoculating the production strain, and the environment should be disinfected.

Principle: Based on the physiological and biochemical characteristics of the bacterial strain, conditions are artificially created to keep the metabolic activity of the bacterial body in a dormant state.

Condition: Select excellent purebred, preferably dormant bodies; Create the most favorable environmental conditions for dormancy, such as reducing the nutrient content of the culture medium, low temperature, drying, oxygen isolation, and adding protective agents.
