Membrane separation technology of microbial fermentation engineering

When it comes to microbial fermentation engineering we should easily be able to think of wine, vinegar, sauce production and bread fermentation, but now the microbial fermentation technology has changed from a branch into a microbiology, chemical engineering, genetic engineering, cell engineering, mechanical engineering and computer hardware and software engineering multidisciplinary projectsThe microbial fermentation engineering is mainly composed of three projects, upstream engineering, fermentation engineering and downstream engineeringOf which, downstream engineering refers to the technology of separating and purifying products from fermentation liquid: including solid-liquid separation technology (centrifugation, filtration separation, precipitation separation and other processes), cell wall breaking technology (ultrasound, high-pressure shear, osmosis pressure, surfactant and wall-to-wall enzyme, etc.), protein purification technology (precipitation, color separation and ultrafiltration) and finallyToday," the small and simple to explain for you the fermentation liquid filtration technology in downstream engineering:p style"text-align-center; "Img src"""alt" "microbial fermentation engineering membrane separation technology" title "microbial fermentation engineering membrane separation technology"fermentation liquid filtration technology is mainly used membrane separation technology, this is The high-tech developed in the past 30 years is a multidisciplinary cross-cutting product, is also a new growth point of chemical engineering, it is compared with the traditional separation method, has the following obvious advantages:1, high efficiency: because the membrane is selective, it can selectively pass through certain substances,and block the transmission of other substances2, energy saving: most membrane separation process at room temperature operation, the separated substances do not occur phase change, is a low energy consumption, low-cost unit operation ; 3, the process is simple, easy to operate and control ; 4, do not pollute the environmentdue to these advantages, so that membrane separation technology in a short period of time rapid development, has been widely and effectively used in petrochemicals, biochemical pharmaceuticals, health care, metallurgy, electronics, energy, light industry, textiles, food, environmental protection, aerospace, maritime transport, people's lives and other fields, forming an independent emerging technology industryat present, the world membrane market at an annual rate of 14% to 30% of the development, it not only formed its own annual output value of about 10 billion U.Sdollars, but also effectively promoted the development of society, economy and science and technologySome of our country's relevant national plans are listed as priority projects, supportIf you are interested in learning about this new fermentation liquid filtration technology, you can view the information on microbial fermentation engineering Read:
