Biocatalytic potential of thermophilic bacteria and actinomycetes
Thermophilic organisms have been less explored due to the difficulties in isolation and maintenance of pure culture. Therefore, it remains to explore their diversity and biotechnological potential from majority of the thermal habitats. As a consequence of growth at high temperature and unique macromolecular properties, thermophiles can possess high metabolic rates, physically and chemically sta...
متن کاملThermoactinomyces Tsiklinsky, a genus of thermophilic actinomycetes.
There has been considerable confusion concerning the nature and classification of thermophilic actinomycetes. Beginning with the early studies of Kedzoir (1896), Berestnev (1897), Tsiklinsky (1899), Gilbert (1904), and Miehe (1907), it was recognized that the actinomycetes capable of growing at higher temperatures (50 to 65 C) represent two distinct groups or types: (1) One group produces a tru...
متن کاملCellulase production by Thermomonospora curvata isolated from municipal solid waste compost.
A cellulolytic, thermophilic actinomycete (previously isolated from municipal refuse compost samples) was identified as Thermomonospora curvata. A determination was made of the optimal conditions for cellulase production by T. curvata when grown at 55 C in a medium containing mineral salts, cellulose, and yeast extract. The pH and temperature optima (pH 6.0 and 65 C) for the cellulase produced ...
متن کاملIsolation of Cellulose-Degrading Actinomycetes and Evaluation of their Cellulolytic Potential
Nine isolates of cellulose-degrading Actinomycetes were isolated from different sediment samples from the Bhitarkanika Mangrove Forest. Cellulase and hydrolytic activity was confirmed with clear zone around the colony on basal salt agar medium using Congo Red. The enzyme assays for two enzymes, filter paper cellulase (FPCase), and carboxymethylcellulase (CMCase), were examined by methods recomm...
متن کاملStudies on the thermophilic actinomycetes. I. Methods of cultivation.
A total of 1,000 isolates of thermophilic actinomycetes representing two genera, Streptomyces and Thermoactinomyces, were studied. Media for cultivation and for physiological studies were designed. Differences between the two genera are noted and taxonomic criteria for the genus Thermoactinomyces are suggested. The importance of the nutritional environment to the thermophilic habit is noted.
