CC-2690 st2-1 pab2 ac14 mt+

$30.00

From Steven Ball, Lille University of Science and Technology, March 1992, his strain B20

Phenotype: altered starch metabolism; requires acetate and p-aminobenzoic acid

This strain is amylose-defective, and accumulates a modified amylopectin. The st2 mutants are analogous to waxy (amylose-deficient) endosperm mutants of higher plants. Because of the pab2 and ac14 mutations, this strain requires acetate and para-amino-benzoic acid (for which yeast extract will suffice).
