Phenotypes of bacterial cells

WebThe mutant bacteria keep up conveyor belt-style cysteine production, secreting the surplus amino acid through the cell membrane into a nutrient medium in 50,000L (over 13,000gal) fermenter tanks. ... Genes can be divided into two categories based on the phenotypes of the corresponding mutants: nonessential gene products are only required under ... WebA phenotype is a property that is genetically determined, but the mutated gene is unknown. For example, a strain that is resistant to phage T1 is referred to as T1 R. The resistance could be due to an insertion sequence in the T1 receptor that is coded by the tonA gene (also known as the fhu A gene).
