Electronic Journal of Biotechnology, 2015 Background: Bacillus subtilis UMC7 isolated from the gut of termite Macrotermes malaccensis has the ability to secrete a significant amount of extracellular endoglucanase, with an enzyme activity of 0.12 ± 0.01 μmol/min/mL.

Activity-dependent adenosine release may be linked to activation of Na+-K+ ATPase : an in vitro rat study [PDF]
, 2014 In the brain, extracellular adenosine increases as a result of neuronal activity. The mechanisms by which this occurs are only incompletely understood. Here we investigate the hypothesis that the Na+ influxes associated with neuronal signalling activate ...

Influence of water activity on the production of extracellular enzymes by Staphylococcus aureus [PDF]
Applied and Environmental Microbiology, 1978 Two enterotoxigenic strains of Staphylococcus aureus were examined for their ability to produce a number of extracellular enzymes at various water activity (alphaw) levels. Supernatant, dialyzed culture media were analyzed for total and relative levels of enzyme activity.

Impact of Trametes versicolor and Phanerochaete chrysosporium on differential breakdown of pesticide mixtures in soil microcosms at two water potentials and associated respiration and enzyme activity. [PDF]
, 2008 This study has examined the effect of inoculation of soil microcosms with Trametes versicolor and Phanerochaete chrysosporium on wood chips on differential degradation of pesticides (simazine, trifluralin and dieldrin, 10 mg kg−1 soil) at two water ...

Evolution of extracellular enzyme activities during manure composting [PDF]
Journal of Applied Microbiology, 2002 Aims: The objectives of this work were to determine the extracellular enzyme profiles during composting, relate the activities of these enzymes to the changes in microbial population and compare the enzyme profiles between two manures. Methods and Results: API ZYMTM assay was used to monitor the activities of 19 extracellular enzymes during poultry and

Bacterial extracellular enzyme activity in a future ocean [PDF]
, 2021 <p>Heterotrophic bacteria are recognised as vital components in the cycling and regulation of inorganic and organic matter in the ocean. Research to date indicates that future changes in ocean conditions may influence bacterial extracellular enzyme hydrolysis rates, which could affect the strength of the microbial loop and consequently organic ...

Water availability affects extracellular hydrolytic enzyme production by Aspergillus flavus and Aspergillus parasiticus [PDF]
, 2009 The objectives of this study were to examine the effect of different water activities (a(w); 0.99, 0.96 and 0.94) and time (up to 120 h) on quantitative and specific enzyme production during germination and initial growth of Aspergillus flavus and A ...

Extracellular enzyme activities potentially involved in the pathogenicity of Mycobacterium tuberculosis [PDF]
Microbiology, 1998 To evaluate the potential contribution of extracellular enzymes to the pathogenicity of mycobacteria, the presence of selected enzyme activities was investigated in the culture filtrates of the obligate human pathogen Mycobacterium tuberculosis, M. bovis BCG, the opportunistic pathogens M. kansasii and M.

Activity-dependent release of Adenosine: a critical re-evaluation of mechanism [PDF]
, 2008 Adenosine is perhaps the most important and universal modulator in the brain. The current consensus is that it is primarily produced in the extracellular space from the breakdown of previously released ATP.
