Novel, attached, sulfur-oxidizing bacteria at shallow hydrothermal vents possess vacuoles not involved in respiratory nitrate accumulation
Article Abstract:
A study is conducted to determine the extent of vacuolization in vacuolate, attached filaments (VAF), the possible correlation between the presence of vacuoles and the accumulation of nitrate and the phylogenetic position of the bacteria relative to nonvacuolate Thiothrix spp. and vacuolate. The analysis indicates that the filaments form within the gamma proteobacteria a monophyletic group that includes all described vacuolate sulfur bacteria.

Identification, mutagenesis, and transcriptional analysis of the methanesulfonate transport operon of Methylosulfonomonas methylovora
Article Abstract:
A study was conducted on the location of the downstream of the msmEF (transport coding) gene cluster, msmGH, and the structural genes for methanesulfonate monooxygenase (MSAMO) from Methylisulfonomonas methylovora. It was observed that the slower growth rates than the wild type was considerably affected by the defective mutant in msmE and thus supported the role of msmE in the transport of MSA into M. methylovora.

Stable carbon isotope ratios of lipid biomarkers of sulfate-reducing bacteria
Article Abstract:
Studies were conducted to examine the potential use of stable carbon isotope ratios of lipids for determining substrate usage by sulfate reducing bacteria. It was found that FA delta13C values could be useful to interpret carbon utilization by sulfate reducing bacteria in natural environments.
