Lactobacillus Exonuclease Mutants: Selection of Mutants with Altered Ability to Utilize Deoxyribonucleotides*
AUTOR(ES)
Hotchkiss, Rollin D.
RESUMO
Lactobacillus acidophilus R-26, which requires preformed deoxyriboside for its growth, is able to grow in a basal medium supplemented with nitrophenyl esters of thymidine 3′- and 5′-phosphates. Mutants unable to grow on the thymidine phosphate esters were isolated and classified thus far into two classes.
