ฉันรักแปล.8 Laboratory Species
E. coli K-12 is the most common strain of E. coli for laboratory use. However, because it is cultured commercially, it has certain attributes that differ from the wild type. Such differentiation includes the loss of resistance to other flora in the gut, and the toxins that such co-existing bacteria produce. As E. coli K-12 is used for many kinds of biological experimentation (mainly recombinant DNA experiments), it is important to know the optimal conditions for growth and the bacteria’s to lerances to certain environmental factors and introduced substances. In order to control as many variables as possible when conducting recombinant DNA experiments, it is ideal to culture E. coli in its optimal growth conditions so as to not induce stress, causing mutation and reproduction of that mutation.
