TY - JOUR T1 - Electron microscope studies of conditional spore cortexless mutants of Bacillus sphaericus. A1 - Imae, Y LA - en YR - 1976 UL - http://buscaintegrada.pucsp.br/vufind/Record/pubmed-232956 AB - Spore cortex of conditional cortexless mutants of Bacillus sphaericus 9602 was not detectable by electron microscopy unless the medium was supplemented with meso-alpha,epsilon-diaminopimelic acid during sporulation. Other spore structures appeared normal. Spore shape was quite irregular in the absence of meso-alpha,epsilon-diaminopimelic acid. KW - Research Article ER -
