Photo-fermentational hydrogen production of Rhodobacter sp. KKU-PS1 isolated from an UASB reactor

Electronic Journal of Biotechnology, 2015
Background: In this study, the detection of nifH and nifD by a polymerase chain reaction assay was used to screen the potential photosynthetic bacteria capable of producing hydrogen from five different environmental sources.

Hsp70 diversification and repurposing across the tree of life: Lessons from the evolutionary and mechanistic trajectory of the Hsp70–Hsp110 chaperone system

The FEBS Journal, EarlyView.
Evolutionary and mechanistic divergence in the Hsp70–Hsp110 chaperone system. Prokaryotic Hsp70s probably diversified into multiple orthologues that cooperated with co‐chaperones such as JDPs and NEF, forming increasingly complex proteostasis networks.

Toward understanding the catalytic mechanism for two classes of bacterial phospholipid N‐methyltransferases

The FEBS Journal, EarlyView.
Phospholipid N‐methyltransferases (Pmts) synthesize phosphatidylcholine in many bacteria. In this study, we compared the catalytic mechanisms of two bacterial Pmt classes: the Rhodobacter (R‐) and the Sinorhizobium (S‐) type. Representative enzymes for each class were derived from Rubellimicrobium thermophilum and Agrobacterium tumefaciens ...

Association Between the Root Canal Microbiome and Apical Lesion Size: An Observational Shotgun Metagenomic Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim The aim was to characterize the taxonomic and functional composition of the microbiome involved in primary endodontic infections and to evaluate their association with the periapical lesion size using shotgun metagenomic sequencing. Methodology Samples from primary root canal infections diagnosed with apical periodontitis were analysed ...

Abundance, Characterization and Diversity of Culturable Anoxygenic Phototrophic Bacteria in Manitoban Marshlands

Microorganisms
Marshes are an important ecosystem, acting as a biodiversity hotspot, a carbon sink and a bioremediation site, breaking down anthropogenic waste such as antibiotics, metals and fertilizers.

Temperature, Disinfectant Concentration and Bacterial Innate Properties Influence the Disinfection of Bacterial Pathogens Relevant to Catfish Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Aquaculture systems suffer a wide range of losses, mostly due to bacterial disease outbreaks, and the use of disinfectants is a routine practice for controlling the spread of pathogenic organisms globally. Including Aeromonas hydrophila, Streptococcus agalactiae and Edwardsiella tarda, implicated for natural disease outbreaks and economic ...

Periodontitis and Inflammatory Bowel Diseases: Mechanistic Evidence

Journal of Periodontal Research, EarlyView.
This review aims to provide a conceptual framework for understanding the mechanistic interplay between periodontitis and IBD, with a particular emphasis on the microbial and immunological crosstalk linking the oral cavity and the gastrointestinal tract.

A Simple Thermodynamic Analysis of Photosynthesis

Entropy, 2007
In this paper we present a comparative study of nine photosynthetic pathways bymeans of their thermodynamic performance. The comparison is made by using the thermalefficiency of light-to-chemical energy conversion and the so-called ecological ...
