Hevea brasiliensis seeds: A novel sustainable feedstock for ethanol production

open access: yesVietnam Journal of Chemistry, EarlyView.
Abstract The rubber tree (Hevea brasiliensis) is cultivated on a large scale mainly for the extraction of latex in Brazil and Southeast Asia, also generating large quantities of seeds. These seeds currently do not have large‐scale applications and may thus be considered as a residue.

Oxygen availability strongly affects chronological lifespan and thermotolerance in batch cultures of Saccharomyces cerevisiae

open access: yesMicrobial Cell, 2015
Stationary-phase (SP) batch cultures of Saccharomyces cerevisiae, in which growth has been arrested by carbon-source depletion, are widely applied to study chronological lifespan, quiescence and SP-associated robustness.

Haloferax volcanii Immersed Liquid Biofilms Develop Independently of Known Biofilm Machineries and Exhibit Rapid Honeycomb Pattern Formation

open access: yesmSphere, 2020
The ability to form biofilms is shared by many microorganisms, including archaea. Cells in a biofilm are encased in extracellular polymeric substances that typically include polysaccharides, proteins, and extracellular DNA, conferring protection while ...

Continuous Anaerobiosis for Cultivation of Spirochetes.

open access: yesExperimental Biology and Medicine, 1964
SummaryApparatus and procedures have been developed for bacteriological work based on a vacuum-tight glove box with lock, in which an anaerobic working atmosphere has been maintained by evacuation, followed by removal of residual and diffusing oxygen with hydrogen and a catalyst that does not require pre-heating.

Effects of Low pH on Lactate Dehydrogenase Kinetics of Diving and Nondiving Reptiles [PDF]

open access: yes, 1986
The properties of lactate dehydrogenase were examined in two snake species, Nerodia rhombifera and Elaphe obsoleta, and a turtle species, Pseudemys scripta.

Redundant and Flexible Electron Transfer Pathways Underlie MsrPQ‐Mediated Repair of Oxidized Periplasmic Proteins

open access: yesMolecular Microbiology, EarlyView.
This study investigates in vivo the role of the flavin reductase Fre as an electron supplier to the periplasmic methionine sulfoxide reductase system MsrPQ. ABSTRACT The MsrPQ system is essential for the repair of oxidized methionine residues in periplasmic proteins, ensuring bacterial resistance to oxidative stress and envelope integrity.

Relative contributions of carbohydrates and proteins to metal mobilisation in an anaerobic soil slurry amended with rum vinasses [PDF]

open access: yes, 2004
The spreading of liquid organic wastes on soils enhances the risks of anaerobiosis and metal mobilisation. Under anaerobiosis, microbial activities drive most of soil geochemical evolutions through reductions, pH changes, net production of mineral and ...

Determination of an Interaction Network between an Extracellular Bacterial Pathogen and the Human Host [PDF]

open access: yes, 2019
A major gap in understanding infectious diseases is the lack of information about molecular interaction networks between pathogens and the human host.

Strict Aerobic Lifestyle and Anaerobic Survival of Bacteria: Inseparable Twins?

open access: yesMolecular Microbiology, EarlyView.
ABSTRACT For many decades the existence of strict aerobic bacteria was part of every textbook. However, considering habitats like soils or surfaces, many of these microorganisms are exposed to drastic changes in oxygen tension. A simple rain shower can change oxygen diffusion rates by a factor of 10.000.
