Dissimilatory metal-reducing bacteria can mobilize As, but few studies have studied such processes in deeper orange-colored Pleistocene sands containing 1-2 mg kg(-1) As that are associated with low-As groundwater in Bangladesh. To address this gap, anaerobic incubations were conducted in replicate over 90 days using natural orange sands initially containing 0.14 mg kg(-1) of 1 M phosphate-extr...

BACKGROUND L-arabinose isomerases catalyse the isomerization of L-arabinose into L-ribulose at insight biological systems. At industrial scale of this enzyme is used for the bioconversion of D-galactose into D-tagatose which has many applications in pharmaceutical and agro-food industries. The isomerization reaction is thermodynamically equilibrated, and therefore the bioconversion rates is shi...

In Shewanella sp. strain ANA-3, utilization of arsenate as a terminal electron acceptor is conferred by a two-gene operon, arrAB, which lacks a gene encoding a membrane-anchoring subunit for the soluble ArrAB protein complex. Analysis of the genome sequence of Shewanella putrefaciens strain CN-32 showed that it also contained the same arrAB operon with 100% nucleotide identity. Here, we report ...

Referente al sector acuícola, uno de los mayores sectores producción alimentos es el cultivo camarón, sin embargo, se ha visto afectado por enfermedades, entre ellas la Enfermedad Necrosis Aguda del Hepatopáncreas (AHPND, sus siglas en inglés) cual causada Vibrio parahaemolyticus que hospeda un plásmido productor tóxinas PirA y Pir B. Un método alternativo para controlar agente causal aplicació...

Here, we present the 5.168-Mbp draft genome sequence of Shewanella baltica M1, the first Shewanella strain from the Gulf of Gdańsk to have its genome sequenced and annotated. The availability of the genome sequence of strain M1 will promote further global analyses of bacterial stress responses in the unique Gulf of Gdańsk ecosystem.
