Arch Microbiol 2019 Feb 1. Epub 2019 Feb 1.

Department of Experimental Biology, Faculty of Science, Masaryk University, Kamenice 753/5, 625 00, Brno, Czech Republic.

Sulfate-reducing bacteria (SRB) belonging to the intestinal microbiota are the main producers of hydrogen sulfide and their increasing amount due to the accumulation of this compound in the bowel are involved in the initiation and maintenance of inflammatory bowel disease. The purpose of this experiment is to study the relative toxicity of hydrogen sulfide and survival of Desulfovibrio piger Vib-7 through monitoring: sulfate reduction parameters (sulfate consumption, hydrogen sulfide production, lactate consumption and acetate production) and kinetic parameters of these processes. The research is highlighting the survival of intestinal SRB, D. Read More

Comparative metagenomic analyses of a high-altitude Himalayan geothermal spring revealed temperature-constrained habitat-specific microbial community and metabolic dynamics.

Arch Microbiol 2019 Jan 25. Epub 2019 Jan 25.

Department of Zoology, University of Delhi, Delhi, India.

Metagenomic surveys across microbial mat (~ 55 °C) samples of high-altitude (1760 m above sea level) Himalayan geothermal springs have revealed specialized community enriched with niche-specific functions. In this study, we have performed metagenomic sequence-based analyses to get insights into taxonomic composition and functional potential of hyperthermophiles in water (~ 95 °C) and sediment samples (78-98 °C). Community analyses revealed predominance of thermophilic bacterial and archeal genera dwelling in water in contrast to microbial mats (55 °C), namely Methylophilus, Methyloversatilis, Emticicia, Caulobacter, Thermus, Enhydrobacter and Pyrobaculum.

Arch Microbiol 2019 Jan 23. Epub 2019 Jan 23.

Department of Animal Sciences and Veterinary Medicine, Shanxi Agricultural University, Taigu, 030801, Shanxi, China.

Intestinal microbiota has been widely recognized to influence on their hosts with respect to digestion and absorption of nutrients, but little is known about the structure and composition of microbial communities at different growth periods of hosts as yet. In this case, 16S rRNA gene amplicon sequencing was applied to decode the microbiota architecture in four distinct intestinal compartments (duodenum, jejunum, ileum, and cecum) of both Large White pigs and Chinese Shanxi Black pigs at the weaning, nursery, and fast-growth developmental stages. In our study, the intestinal ecosystems were dynamically changing and influenced by host maturity and diets at different development stages. Read More

Department of Biochemistry and Molecular Biology, UFPR, Curitiba, PR, Brazil.

The committed and rate-limiting step in fatty acid biosynthesis is catalyzed by acetyl-CoA carboxylase (ACC).

Modulation of nitrogen metabolism of maize plants inoculated with Azospirillum brasilense and Herbaspirillum seropedicae.

Arch Microbiol 2018 Nov 17. Epub 2018 Nov 17.

Embrapa Agrobiologia, BR 465-km 07, Seropédica, Rio de Janeiro, CEP 23891-000, Brazil.

Maize is highly responsive to the application of nitrogen to achieve high productivity. Inoculation with diazotrophic bacteria can improve plant growth with low N fertilization. The objective was to evaluate the inoculation of two species of diazotrophs on N metabolism in maize plants, in the presence of two concentrations of nitrogen in a hydroponic system. Read More

Pharmacological properties of marine macroalgae-associated heterotrophic bacteria.

Arch Microbiol 2018 Nov 7. Epub 2018 Nov 7.

Central Marine Fisheries Research Institute, Ernakulam North, P.B. No. 1603, Cochin, Kerala State, India.

The rich diversity of marine macroalgae and their associated bacterial flora represent a potential reservoir of bioactive compounds with valuable biotechnological and pharmaceutical use. Heterotrophic bacteria associated with the intertidal macroalgae were isolated and evaluated for their pharmacological properties using various in vitro models. Among 148 cultivable isolates, more than 50% were dominated by γ-Proteobacteria and Firmicutes, wherein 53 of them showed consistent antibacterial activity against a broad spectrum of clinically significant pathogens.

The role of the NADH-dependent nitrite reductase, Nir, from Escherichia coli in fermentative ammonification.

Arch Microbiol 2018 Nov 7. Epub 2018 Nov 7.

Roy J Carver Department of Biochemistry Biophysics and Molecular Biology, Iowa State University, 4116 Molecular Biology Building, Ames, IA, 50011, USA.

Nitrate and nitrite reduction are of paramount importance for nitrogen assimilation and anaerobic metabolism, and understanding the specific roles of each participating reductase is necessary to describe the biochemical balance that dictates cellular responses to their environments. The soluble, cytoplasmic siroheme NADH-nitrite reductase (Nir) in Escherichia coli is necessary for nitrate/nitrite assimilation but has also been reported to either "detoxify" nitrite, or to carry out fermentative ammonification in support of anaerobic catabolism. Theoretically, nitrite detoxification would be important for anaerobic growth on nitrate, during which excess nitrite would be reduced to ammonium. Read More

Free radical stress induces DNA damage response in RAW264.7 macrophages during Mycobacterium smegmatis infection.

Arch Microbiol 2018 Nov 1. Epub 2018 Nov 1.

Department of Molecular Biology and Bioinformatics, Tripura University, Suryamaninagar, Tripura, 799022, India.

Genomic instability resulting from oxidative stress responses may be traced to chromosomal aberration. Oxidative stress suggests an imbalance between the systemic manifestation of reactive free radicals and biological system's ability to repair resulting DNA damage and chromosomal aberration. Bacterial infection associated insult is considered as one of the major factors leading to such stress conditions. Read More

The rhizomicrobiomes of wild and cultivated crops react differently to fungicides.

Arch Microbiol 2018 Oct 25. Epub 2018 Oct 25.

Key Laboratory of Mollisols Agroecology, Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences, Changchun, 130102, Jilin, China.

The fungicides used to control diseases in cereal production can have adverse effects on non-target microbial communities, with possible consequences for plant health and productivity. Although we know that fungicides affect microbial community structure and soil activities, it is unclear how crop cultivars have altered the impact of fungicides on rhizomicrobiomes. In this study, the rhizosphere bacterial and fungal communities and structures of cultivated crops and their wild relatives were studied by Illumina MiSeq sequencing analysis. Read More
