Lyngbya Sp.: a Suitable Cyanobacterium for Harvesting Antimicrobial Compounds
Lyngbya spp. is one of the most efficient groups of secondary metabolite producers and is very important from pharmaceutical point of view. Among its various species, majuscula is the major producers of commercially important biomolecules. Several species have been isolated and screened from the marine in the past decades. Although the chance of isolating a novel Lyngbya strain from a marine ha...
متن کاملPurification and structure elucidation of antifungal and antibacterial activities of newly isolated Streptomyces sp. strain US80.
A new actinomycete strain, designated US80 and producing antimicrobial activities against Gram-positive and Gram-negative bacteria and fungi, was isolated from Tunisian oasis soil. Cultural characteristic studies strongly suggested that this strain belongs to the genus Streptomyces. The nucleotide sequence of the 16S rRNA gene (1517 pb) of Streptomyces sp. strain US80 exhibited close similarity...
متن کاملContinuing studies on the cyanobacterium Lyngbya sp.: isolation and structure determination of 15-norlyngbyapeptin A and lyngbyabellin D.
Re-collections of the cyanobacterium Lyngbya sp. have yielded two more members of the lyngbyapeptin and lyngbyabellin families. The gross structures of 15-norlyngbyapeptin A (1) and lyngbyabellin D (3) were deduced through standard 2D NMR techniques, with the absolute configuration of both elucidated through degradation and comparison with commercially available and synthetic standards. Degrada...
متن کاملIsolation and structure elucidation of two new antibacterial compounds produced by Chrysosporium queenslandicum.
During our investigation on bioactive antifungal pigments the strain Chrysosporium queenslandicum IFM 51121 was found to produce a series of darkish to reddish pigments which were identified as naphthaquinone-type altersolanols A, B, C1-3). Moreover, a new antifungal compound (queenslandon)4) was isolated as a new representative of the zearalenone family of mycotoxin. In addition to the above m...
متن کاملIsolation and Structure Elucidation of Secondary Metabolites from Echinophora platyloba DC from Iran
Background: Echinophora platyloba DC (Apiaceae) is one of the two endemic species of Echinophora genus in Iran. It has many folkloric uses and several biological activities but there is no information about its phytoconstituents. Objective: In this work some of the secondary metabolites were isolated, purified and identified from n-hexane, ethyl acetate and methanol extracts from the aerial pa...
