Mannitol, a compatible solute synthesized byAcinetobacter baylyiin a two-step pathway including a salt-induced and salt-dependent mannitol-1-phosphate dehydrogenase

Autor: Volker Müller, Miriam Sand, Helena Santos, Ana Mingote, Beate Averhoff

Publikováno v: Environmental Microbiology. 15:2187-2197

Summary The nutritionally versatile and naturally competent soil bacterium Acinetobacter baylyi copes with salt stress by the accumulation of compatible solutes. NMR analyses revealed that cells amassed glutamate and the rather unusual sugar alcohol

Publikováno v: Planta. 237:891-901

A mannosylglycerate synthase (MgS) gene detected in the genome of Selaginella moellendorffii was expressed in E. coli and the recombinant enzyme was purified and characterized. A remarkable and unprecedented feature of this enzyme was the ability to

Salt adaptation in Acinetobacter baylyi: identification and characterization of a secondary glycine betaine transporter

Autor: Véronique de Berardinis, Helena Santos, Stephan Göttig, Miriam Sand, Ana Mingote, Beate Averhoff, Volker Müller

Publikováno v: Archives of Microbiology. 193:723-730

Members of the genus Acinetobacter are well known for their metabolic versatility that allows them to adapt to different ecological niches. Here, we have addressed how the model strain Acinetobacter baylyi copes with different salinities and low wate

Are Compatible Solutes Compatible with Biological Treatment of Saline Wastewater? Batch and Continuous Studies Using Submerged Anaerobic Membrane Bioreactors (SAMBRs)

Autor: Ana Mingote, Michael J. Ray, Ioannis Vyrides, David C. Stuckey, Helena Santos

Publikováno v: Environmental Science & Technology. 44:7437-7442

This study investigated fundamental mechanisms that anaerobic biomass employ to cope with salinity, and applied these findings to a continuous SAMBR. When anaerobic biomass was exposed to 20 and 40 g NaCl/L for 96 h, the main solute generated de novo

A novel limb in the osmoregulatory network ofMethanosarcina mazeiGö1: Nε-acetyl-β-lysine can be substituted by glutamate and alanine

Autor: Helena Santos, Regina Saum, Ana Mingote, Volker Müller

Publikováno v: Environmental Microbiology. 11:1056-1065

N(epsilon)-acetyl-beta-lysine is a unique compatible solute found in methanogenic archaea grown at high salinities. Deletion of the genes that encode the lysine-2,3-aminomutase (ablA) and the beta-lysine acetyltransferase (ablB) abolished the product

Genetic analysis of the role of the ABC transporter Ota and Otb in glycine betaine transport in Methanosarcina mazei Gö1

Autor: Regina Saum, Volker Müller, Ana Mingote, Helena Santos

Publikováno v: Archives of Microbiology. 191:291-301

The methanogenic archaeon Methanosarcina mazei Gö1 accumulates glycine betaine in response to hypersalinity but differs from most other methanoarchaea in having two gene clusters both encoding a potential glycine betaine transporter, Ota and Otb. We
