A novel lumazine peptide, penilumamide (1), was isolated from the fermentation broth of a marine-derived fungal strain, identified as Penicillium sp. (strain CNL-338) and the structure of the new metabolite was determined by analysis of ESI-TOF MS data combined with 1D and 2D NMR experiments.

Microbacterium (formerly Corynebacterium) sp. No. 7 was isolated from activated sludge as a polypropylene glycol (PPG)-assimilating bacterial strain. Its oxidative PPG degradation has been proposed on the basis of PPG dehydrogenase activity and the metabolic products. Here, we report the complete genome sequence of Microbacterium sp. No. 7. The genome of the strain No. 7 is composed of a 4,599,...

in the present study, an efficient protocol has been developed for callus induction and production of ra in callus culture of satureja khuzistanica for the first time. in vitro callus induction was achieved from young shoot tip explants cultured on ms and b5 media supplemented with different concentrations of iba (0.1, 1.0, 2.0 and 5.0 mgl-1) solely or in combination with cytokinins bap and kin...

BACKGROUND Oxygenic photosynthetic microorganisms such as cyanobacteria and microalgae have attracted attention as an alternative carbon source for the next generation of biofuels. Glycogen abundantly accumulated in cyanobacteria is a promising feedstock which can be converted to ethanol through saccharification and fermentation processes. In addition, the utilization of marine cyanobacteria as...

Dongfang no.7 (Saccharina japonica) was bred and maintained by hybridizing gametophytes, self-crossing the best individuals, selecting the best self-crossing line and seedling-raising from yearly reconstructed sporophytes. It increased the air dry yield by 43.2% in average over 2 widely farmed controls. Dongfang no.7 was seedling-raised from bulked sporophytes reconstructed from its representat...

Four new metabolites, including three new oblongolides named C1, P1, and X1 (1-3) and 6-hydroxyphomodiol (10), along with eight known compounds--oblongolides B (4), C (5), D (6), O (7), P (8) and U (9), (3R,4aR,5S,6R)-6-hydroxy-5-methylramulosin (11), and (3R)-5-methylmellein (12)--were isolated from the endophytic fungal strain Phomopsis sp. XZ-01 of Camptotheca acuminate. Their structures wer...

Pseudomonas sp. strain TKP does not degrade γ-hexachlorocyclohexane (γ-HCH), but it persistently coexists with the γ-HCH-degrading Sphingobium sp. strain TKS in a mixed culture enriched by γ-HCH. Here, we report the complete genome sequence of strain TKP, which consists of one circular chromosome with a size of 7 Mb.

Microbial electrochemical technologies are becoming an interest for the community due to their possible applications in wastewater treatment, biosensing, biosynthesis, and bioenergy. Fundamental these is use of electroactive microorganisms as bioelectrocatalysts. Recent studies have aimed elucidate electron transfer strategies microorganisms, with a keen extremophilic bacteria enhanced survivab...

The genus Salinivibrio includes obligatory halophilic bacteria and is commonly isolated from hypersaline habitats and salted food products. They grow optimally between 7.5 and 10% salts and are facultative anaerobes. Currently, this genus comprises four species, one of them, S. costicola, with three subspecies. In this study we isolated and characterized an additional 70 strains from solar salt...
