group q streptococci. i. ecology, serology, physiology, and relationship to established enterococci. | the group q streptococci possess unique serological and physiological characteristics which differentiate them from established enterococci. the group q antigen was not demonstrable in all strains; however, all possessed the group d antigen. all group q strains were physiologically similar regardless of whether or not they possessed the group q antigen. these strains differed from the established enterococcal species, as they neither hydrolyzed arginine nor initiated growth in 1.0% methylene blu ... | 1967 | 4962699 |

influence of isoleucine upon quinomycin biosynthesis by streptomyces sp. 732. | when dl-isoleucine was added to an ammonium nitrate-maltose medium during cultivation of streptomyces sp. 732, quinomycin b formation was selectively enhanced (from 3 to 70% of the quinomycin mixture) and quinomycin c synthesis was inhibited completely. in addition, two new quinomycins, designated quinomycins d and e, were produced in the presence of isoleucine. these compounds were found to contain n-methylalloisoleucine. in experiments with isoleucine enantiomorphs, it was determined that the ... | 1967 | 6032510 |

release of sporangiospores by a strain of actinoplanes. | dehiscence of actinoplanes sp. 7-10 sporangia is triggered by wetting of the spores. this process requires time because of the hydrophobic nature of the sporangial envelope; it can be speeded up and enhanced by a wetting agent. once wetted, the spores swell, usually ripping the sporangial wall, and escape as motile elements when functional flagella are synthesized. flagellation and motility are separate phenomena, both of which lose intensity with age. spores from old sporangia can regain motili ... | 1967 | 6071921 |
