Article history: Received on: 11/04/2016 Revised on: 09/05/2016 Accepted on: 24/06/2016 Available online: 29/10/2016 Drug resistance in microorganisms is an emerging phenomenon that poses challenges to public health and treatment. The reservoir of drug resistance genes found in the resistome of environmental isolates in aquatic saline systems has been augmenting continuously. The spread of drug...

A DNA fragment carrying the gene encoding poly(3-hydroxybutyrate) (P(3HB)) depolymerase was cloned from the genomic DNA of Marinobacter sp. DNA sequencing analysis revealed that the Marinobacter sp. P(3HB) depolymerase gene is composed of 1734bp and encodes 578 amino acids with a molecular mass of 61,757Da. A sequence homology search showed that the deduced protein contains the signal peptide, ...

The danger of a petroleum hydrocarbon spillage in the polar, ice-covered regions is increasing due to oil exploration in Arctic offshore areas and a growing interest in using the Northern Sea Route (NSR) as an alternative transportation route for Arctic oil and gas. However, little is known about the potential impact of accidental oil spills on this environment. We investigated the impact of cr...

The genus of Marinobacter is one of the most ubiquitous in the global oceans and assumed to significantly impact various biogeochemical cycles. The genome structure and content of Marinobacter aquaeolei VT8 was analyzed and compared with those from other organisms with diverse adaptive strategies. Here, we report the many "opportunitrophic" genetic characteristics and strategies that M. aquaeol...

Thirteen species of helminth parasites were recovered from six species of charadriid shorebirds (Aves: Charadriiformes) from Belize: the ruddy turnstone, Arenaria interpres, the snowy plover, Charadrius alexandrinus, the semipalmated plover, C. semipalmatus, the killdeer, C. vociferus, the white-rumped sandpiper, Calidris fuscicollis, and the black-bellied plover, Pluvialis squatarola. Cestode ...

Two new names, Dracaena neoparviflora and ridleyii are proposed as replacement names for the illegitimate D. parviflora Baker, nutans Ridl., respectively, latter being a later homonym of Willd. ex Schult.f., H.Jaeger. Lectotypes designated D.cambodiana, interrupta (synonym camerooniana), oddonii cantleyi, cinnabari, cuspidibracteata congoensis), haemanthoides, litoralis braunii), parviflora, no...

The discovery of hyperthermophilic microorganisms and the analysis of hyperthermostable enzymes has established the fact that multisubunit enzymes can survive for prolonged periods at temperatures above 100°C. We have carried out homology-based modeling and direct structure comparison on the hexameric glutamate dehydrogenases from the hyperthermophiles Pyrococcus furiosus and Thermococcus litor...
