A filamentous division mutant, PV302, of Bacillus megaterium QM B1551 was isolated while screening for sporulation-defective mutants after nitrosoguanidine mutagenesis. Both phase-contrast and electron microscopy revealed that the mutant produced small spherical cells as well as filaments. It also accumulated large amounts of poly-beta-hydroxybutyrate. Poly-beta-hydroxybutyrate accounted for 16% of the dry weight of the mutant strain even after 28 h growth. In comparison to the parental strain… CONTINUE READING
