Cells respond to a variety of signals by activation of a phospholipase C which catalyzes the phosphodiesteric cleavage of phosphatidylinositol 4,5bisphosphate to generate intracellular second messengers, inositol 1,4,5-trisphosphate and 1,2diacylglycerol. Previously, we described the isolation of an inhibitor for inositol-specific phospholipase C from Actinomadura sp. This inhibitor therefore m...

In a taxonomic study on form-species of form-genus Cytospora, about four hundred fungal specimens were collected from all over the Iran during 2003-2005. In this paper, the second part of the obtained results, including seven form-species are presented. Cytospora intermedia, C. kantschavelii, C. leucosperma and C. ribis are reported as new members for mycoflora of Iran. Salix aegyptiaca for C. ...

A scheme has been developed for the identification of thermophilic actinomycetes associated with hypersensitivity pneumonitis. Eighty strains, 10 Micropolyspora faeni, 6 Saccharomonospora viridis, 52 Thermoactinomyces candidus, 7 T. vulgaris, 4 T. sacchari, and 1 T. dichotomica, either isolated from patients' environment or received as authentic strains, were studied. In addition to the cultura...

The objective of this study was to examine the alkalithermophilic actinomycete communities in the subtropical environment of Jujuy, Argentina, characterized by sugarcane crops. Laceyella putida, Laceyella sacchari, Thermoactinomyces intermedius, Thermoactinomyces vulgaris and Thermoflavimicrobium dichotomicum were isolated on the media with novobiocin, from sugar cane plants and renewal rhizosp...
