What is bacterial strain improvement?

That is, genetic breeding is used to mutate and reorganize the DNA of the genetic factor of wild-type strains (original strains isolated and screened from nature), so that high yields, good quality of finished products, or new culture characteristics such as resistance products can be selected. Suppression, use of cheap raw materials and good strains with the ability to produce new varieties.

The methods used are mutation breeding, cross breeding, cell fusion techniques and recombinant DNA techniques.

Mutation breeding is the use of mutagenic factors such as ultraviolet, cobalt-60, ethyleneimine and other physical or chemical mutagens to treat the production of strains of single spore suspension to obtain induced mutant strains. Subsequent screening of the mutants was performed and high-yield strains were selected therefrom. Due to the low proportion of beneficial mutations in the random mutation population, a large number of screening must be performed to obtain high-yield mutant strains. In recent years, with the development of metabolic control of fermentation, it is possible to increase the yield or other characteristics according to the reaction points in the biosynthetic pathway and through their alterations, such as the selection of mutants that inhibit the feedback inhibition of the product and increase the cell permeability. Mutant strains, auxotrophic mutants, etc. This "rational screening method" is widely used in breeding of amino acid-producing bacteria.

Small 2D LiDAR Sensor

IT02S, is JRT new product in the early 2019, which is a single-point LiDAR sensor, also called tof distance sensor. With a micro size of 46x17x7mm, customers can widely use in many Laser Measurement Solutions. The lidar distance sensor can measure 12m short-range with high frequency up to 100hz. It's great for Unmanned Aerial Systems. If you need us send you data sheet and spec for this products, offering sample as well, pls tell us, thank you.
