Emergence of a laccase-positive variant of Azospirillum lipoferum occurs via a two-step phenotypic switching process.

FEMS microbiology letters - 15 May 1999

Alexandre G, Bally R

Abstract excerpt

Two variants have been isolated from the wild-type Azospirillum lipoferum strain 4B. The first variant, 4V(I), spontaneously emerged from the wild-type at frequencies in the order of 10(-4) to 10(-3) per cell generation. Compared to the wild-type, the 4V(I) variant gained (production of a carotenoid-like pigment, assimilation of certain carbohydrates) and lost (swimming motility, reduction of triphenyl...
