Streptomycetes are a group of environmental bacteria present in almost all kinds of environments. They are common in soil, but also found in sediments, composts and fodder, aquatic habitats, and buildings. In buildings they have been associated with moisture conditions that enable microbial growth, and thus, considered as indicators of moisture and microbial damage. Streptomycetes are also pote...

The thermophilic streptomycetes, growing in the temperature range of 55 to 65 C, have remained a little known group of microorganisms. Since their discovery in 1888 by Golbig, their physiology, metabolism, metabolic products, natural habitat, and even their morphology have remained unknown or in the realm of conjecture. It was only in the latest edition of Bergey's Manual of Determinative Bacte...

A study of the bacteriolytic properties of streptomycetes has progressively uncovered the production by these microorganisms of a large number of different enzymes acting upon various bacterial constituents, especially on some of them located in the cell wall. Although the mechanism of the bacteriolysis is far from being completely elucidated at present, it can, however, be stated that, in two ...

Streptomycetes are filamentous bacteria that produce numerous valuable compounds, including the majority of clinically used antibiotics. At an industrial scale, most of these compounds are produced in bioreactors. Growth of streptomycetes under these conditions is characterized by the formation of complex mycelial particles, whose sizes follow a bimodal distribution. Given the correlation betwe...

To develop a host-vector system in streptomycetes for DNA cloning, we examined the technical problems encountered and the conditions required for use of Streptomyces kasugaensis MB273 as the host. Basic techniques, such as plasmid DNA isolation, regeneration of mycelia from protoplasts and elimination of plasmids from cells were investigated. These techniques were found to be useful for many st...
