CHARACTERIZATION OF SOD-INDUCED ALFALFA SEEDLING INJURY (ALLELOPATHY, ANAEROBIOSIS)
<p>Field and greenhouse studies were conducted to examine the seedling vigor of sod-sown alfalfa (Medicago sativa L.).</p><p>Seedlings grown in tilled soil had more dry matter, were taller, and had longer internodes than seedlings in sod. Node number and plant density were reduced in some …

The production of 4-adminobutyrate in response to treatments reducing cytosolic pH and the regulation of intracellular pH
… response to varied stress conditions including anaerobiosis. Recent papers suggest that GABA production and associated H+ consumption are parts of a metabolic pH-stat mechanism which ameliorates the intracellular pH decline associated with anaerobiosis or other treatments. To test this …

Molecular characterization and promoter analysis of the maize cytosolic glyceraldehyde 3-phosphate dehydrogenase gene family
… the gpc multi-gene family, gpc3, increase under anaerobiosis. This study extends further analysis of the gpc gene family, with specific emphasis on gpc4. Analysis of full length cDNA clones for GAPC2, GAPC3 and GAPC4 revealed that the deduced amino acid sequence of GAPC4 has 99.4% identity with …

Blood lactate levels during exercise : the effects of exercise duration, bicarbonate infusion and beta-receptor antagonism
… accumulation occurs either as a result of muscle anaerobiosis or an "overflow" of oxygen-independent glycolysis.

Interrogation of Yeast Responses to Anaerobic Growth Conditions at the Intact Protein Level Using Improved Top-Down Proteomics
… the response of Saccharomyces cerevisiae towards anaerobiosis. Approximately 150 protein pairs were measured with 4 differential expressions determined including an aerobic and anaerobic isoform. Direct comparison of PTM patterns between two cell states was also accomplished through top-down …

Cloning and characterisation of a bZIP transcription factor from a resurrection grass, Eragrostis nindensis
… to a range of environmental signals including anaerobiosis, dehydration and light as well as by abscisic acid (ABA). Basic leucine zipper (bZIP) transcription factors have been shown to specifically bind and activate transcription from G-boxes in a dimerized form. A 1.5 kb cDNA for a bZIP class …

The Aerobic Metabolism and Behavior of the Burrow-dwelling Mantis Shrimp, HEMISQUILLA ENSIGERA CALIFORNIENSIS
… does not fit well into either the "environmental anaerobiosis" or "facultative anaerobiosis" categories. During times of relative anoxia within the burrow the animal maintains a moderate level of activity instead of the quiescence normally expected under hypoxic conditions. </p>

Cardiac, ventilatory and metabolic responses of two ecologically distinct species of fish to waterborne cyanide
… exposure were measured to estimate the extent of anaerobiosis. Whole-body lactate levels were greater in the bullheads than the trout, indicating a higher capacity for anaerobiosis, probably due to a greater fuel supply. Whole-body pyruvate levels in both species did not change from control levels …

Comparative phosphorus removals using modified activated sludge processes
… predominate phosphorus removal mechanism. 6. The anaerobiosis and acid stripping procedure, as used in this investigation, is not effective in enhancing either a biological or chemical unit's ability to remove phosphorus.

Oxidative stress in anoxic habitats
… looks into the molecular basis of obligate anaerobiosis. Previous reports have identified three points of oxidative damage in the central metabolism of B. thetaiotaomicron. Two of these enzymes, fumarase and pyruvate formate lyse (PFL), were reported to be damaged by O2- and molecular O2 …

The effect of mean cell residence time on the dewatering characteristics of a biological sludge
… and it was affected by conditioning, periods of anaerobiosis, and MCRT in the laboratory reactors.

Municipal yard waste composting: process parameters, windrow gases, and leachate quality
… 4x10⁻² mmol/l reflects inconsequential anaerobiosis. Leachate from individual windrows was minimal but contained high concentrations of total Kjehldahl nitrogen (TKN), total phosphorus, and biological oxygen demand. Soil degradation processes should ameliorate these. The leaf/grass mix …

A study of the "Phoenix phenomenon" in Clostridium perfringens
… The effect of sporulation, age of inoculum, anaerobiosis, assay medium, growth inhibitors, and diluent were studied. The "Phoenix phenomenon" was reproduced in experiments using sporulation negative mutants derived from HT₉, various ages of inocula, and under strict anaerobic conditions. …

Evaluation Of Prefermentation As A Unit Process Upon Biological Nutrient Removal Including Biokinetic And Wastewater Parameters
… PHA formation and glycogen consumption during anaerobiosis of prefermented influent. • Improvements in biological P removal of septic, non-P limited wastewater occurred even when all additional VFA production exceeded VFA requirements using typical design criteria (e.g. 6 g VFA per 1 g P …

Pigment composition in heterotrophically and photoheterotrophically grown rhodopseudomonas capsulata
… were different. After a typical transfer, anaerobiosis was rapidly achieved but there was a 50 minute lag before the onset of RITA synthesis, and there was no growth for 20 hours. Pigment changes observed, thus occurred while the cells were not growing. Bchl concentrations began to increase …

The process intensification of biological hydrogen production by Escherichia coli HD701
… survey that showed a need for microaerobiosis or anaerobiosis during growth (for mixed acid fermentation to occur) along with a high formate concentration necessary for the transcription of the FHL complex (the hydrogen gas evolving enzyme). For this reason the KLa from the initial shake flask …

The impact of bile and anaerobic stress on Listeria monocytogenes isolates
… more varied resistance patterns. The effect of anaerobiosis is not as well understood as aerobic and results provide an insight into the influence of environmental factors. Interestingly, the bile resistance assay revealed that the clinical isolates were significantly more tolerant to bile than …

Anaerobic Dissipation of Herbicides in Microbiologically Induced Soil Redox Regimes
Herbicides may encounter anaerobiosis as a result of soil flooding, poor drainage, or offsite transport. Anaerobic dissipation of herbicides in the environment is poorly understood. The objective of this research was to characterize the anaerobic fates of herbicides atrazine, trifluralin, and …
