MICROBIOLOGY

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Microbial yield improvement can be carried out by using ____
A
Mutation
B
Microbial selection
C
Recombinant DNA
D
Microbial screening
E
Genetically engineered
Explanation: 

Detailed explanation-1: -For example, genetic engineering may involve adding a gene from one species to an organism from a different species to produce a desired trait. Used in research and industry, genetic engineering has been applied to the production of cancer therapies, brewing yeasts, genetically modified plants and livestock, and more.

Detailed explanation-2: -Genetic improvement of microbial starter cultures is most appropriate for those fermentations that rely solely or primarily on one microorganism. In many cases, our knowledge about the fermentation is limited, making selection of the target strain very difficult.

Detailed explanation-3: -Microbes can develop biological resistance to any toxic substance in the environment due to specialized jumping genes. There are two methods, ex situ and in situ, which are employed for the bioremediation of contaminated soils.
