[ 1 ] - Genetic analysis of polyketide synthase and peptide synthase genes of cyanobacteria as a mining tool for new pharmaceutical compounds
Cyanobacteria are considered a promising source for new pharmaceutical lead compounds and a large number of chemically diverse and bioactive metabolites have been obtained from cyanobacteria. Despite of several worldwide studies on prevalence of NRPSs and PKSs among the cyanobacteria, none of them included Iranian cyanobacteria of Kermanshah province. Therefore, the aim of this study was t...
[ 2 ] - Identification and toxigenic potential of a cyanobacterial strain (Stigomena sp.)
Cyanobacteria are well known for their production of a multitude of highly toxic substances . The genus Stigomena is regarded as good candidates for producing biologically active secondary metabolites, which are highly toxic to humans and other animals. The carcass of a dog was found at the shore of Lake Ali-Abad, Iran. Biomass from the discovery site appeared to be of cyanobacterial nature. We...
[ 3 ] - Molecular phylogenetic and morphometric evaluation of Calothrix sp. N42 and Scytonema sp. N11
The taxonomy of cyanobacteria has been substantially modified in the last few decades, particularly after application of modern ultra structural and molecular methods. The present research, therefore, aimed to investigate, through a polyphasic approach, the differences in morphological and genotypic features of two cyanobacteria strains isolated from different agricultural and freshwaters areas...
[ 4 ] - A proposal for the unification of two cyanobacterial strains of Nostoc as the same species
The present research aimed to investigate through a polyphasic approach, the differences in morphological and genotypic features of two cyanobacterial strains isolated from paddy fields of northern parts of Iran, belonging to the family Nostocaceae (subsect. IV. I). Based on the reliable identification keys, the two strains were identified as Nostoc ellipsosporum (Desm.) Rabenh. ex Born. et Fla...
[ 5 ] - A Report on Finding a New Peptide Aldehyde from Cyanobacterium Nostoc sp. Bahar M by LC-MS and Marfey’s Analysis
Background: Cyanobacteria have a worldwide distribution in the terrestrial habitats, occurring predominantly on the surface of the soils, stones, rocks, and trees, practically in moist, neutral or alkaline aeries. The unique natural and bioactive compounds from cyanobacteria with various biological activities and an extensive range of chemical classes have a significant capabil...
