Sporulation of Streptomyces griseus in submerged culture.
A wild-type strain of Streptomyces griseus forms spores both on solid media (aerial spores) and in liquid culture (submerged spores). Both spore types are highly resistant to sonication, but only aerial spores are resistant to lysozyme digestion. Electron micrographs suggest that lysozyme sensitivity may result from the thinner walls of the submerged spores. Studies of the life cycle indicate t...
متن کاملDeprogrammed sporulation in Streptomyces.
The bacterial genus Streptomyces forms chains of spores by septation at intervals in aerial hyphae and subsequent maturation on solid medium. Substrate hyphae undergo extensive lysis, liberating nutrients on which aerial hyphae develop. Some mutant strains, however, ectopically form spores by septation in substrate hyphae on solid medium or in vegetative hyphae in liquid medium, which suggests ...

Mycelium differentiation and antibiotic production in submerged cultures of Streptomyces coelicolor.
Despite the fact that most industrial processes for secondary metabolite production are performed with submerged cultures, a reliable developmental model for Streptomyces under these culture conditions is lacking. With the exception of a few species which sporulate under these conditions, it is assumed that no morphological differentiation processes take place. In this work, we describe new dev...

abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
