Nostoc thermotolerans sp. nov., a soil-dwelling species of Nostoc (Cyanobacteria)

Paenibacillus glycanilyticus sp. nov., a novel species that degrades heteropolysaccharide produced by the cyanobacterium Nostoc commune.

A novel bacterial strain, DS-1T, was isolated that degrades heteropolysaccharide produced by the cyanobacterium Nostoc commune. The isolate was identified by a combination of phenotypic characterization, cellular fatty acid analysis, DNA base composition, DNA-DNA hybridization and 165 rRNA gene sequence analysis. Phylogenetic analysis placed strain DS-1T within the Paenibacillus cluster on a ph...

Identification of sesquiterpene synthases from Nostoc punctiforme PCC 73102 and Nostoc sp. strain PCC 7120.

Cyanobacteria are a rich source of natural products and are known to produce terpenoids. These bacteria are the major source of the musty-smelling terpenes geosmin and 2-methylisoborneol, which are found in many natural water supplies; however, no terpene synthases have been characterized from these organisms to date. Here, we describe the characterization of three sesquiterpene synthases ident...

Transcriptional regulation of two putative proteases in the cyanobacteria Nostoc sp. PCC 7120

Antibacterial activity of two soil cyanobacteria Nostoc polludosum and Cylindrospermum licheniforme

Antibacterial activity of two cyanobacterial strains i.e. Nostoc polludosum and Cylindrospermum licheniforme was studied. Both cyanobacterial strains were isolated from agricultural fields of Varanasi, India. Crude extracts of both strains in five solvents i.e. Ethanol, Petroleum ether, Acetone, Methanol, and Chloroform were screened against two human pathogenic bacteria i.e. S. aureus and E. c...

The crude oil biodegradation by Fisherella and Nostoc Cyanobacteria

The purpose of this study was to investigate the growth and potential of crude oil biodegradation by Fischerella and Nostoc. In this study, the growth rate of cyanobacterial species such as Fischerella sp. ISC107 and Nostoc sp. ISC101 were determined using chlorophyll-a content measurement at 663nm under different treatments of crude oil (control, 0.1, 0.2, 0.4, 0.8 and 1.6%). The crude oil con...
