Glucose Catabolism in Strains of Acidophilic, Heterotrophic Bacteria [PDF]

Applied and Environmental Microbiology, 1985
Pathways of glucose catabolism, potentially operational in six strains of obligately aerobic, acidophilic bacteria, including Acidiphilium cryptum strain Lhet2, were investigated by short-term radiorespirometry and enzyme assays. Short-term radiorespirometry was conducted at pH 3.0 with specifically labeled [

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Microphytobenthic extracellular polymeric substances (EPS) in intertidal sediments fuel both generalist and specialist EPS-degrading bacteria [PDF]

, 2013
Microphytobenthic biofilms contain high concentrations of carbohydrate-rich extracellular polymeric substances (EPS) that are important in sediment carbon cycling.

Thermodynamic Evaluation of Dual Substrate Growth

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Various C₁–C₂ compounds are increasingly available through electrochemical reduction of CO2. Although not always suitable as a sole substrate, these compounds can supplement a primary substrate like glucose to enhance microbial growth. Yet, the mechanisms underlying the effects of dual substrate consumption on growth rate and growth yield ...

Effect of temperature on mineralization by heterotrophic bacteria [PDF]

Applied and Environmental Microbiology, 1980
When pure cultures of the bacteria Pseudomonas fluorescens (a psychrotroph), Escherichia coli (a mesophile), and SRL 261 (a thermophile) were shifted away from temperatures to which they were adapted, the percentage of substrate mineralized increased (percent mineralized = [substrate respired to CO2]/substrate respired to CO2 + substrate incorporated ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Antimicrobial agents derived from heterotrophic bacteria againts pathogenic bacteria

IOP Conference Series: Earth and Environmental Science, 2019
Abstract Pathogenic bacteria often cause problems in fish farming. Prevention efforts using synthetic antibiotics may engender negative impacts on the environment. Accordingly, the use of natural antimicrobial compounds is required to minimize the risk.
