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.

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 ...

Wakefulness affects synaptic and network activity by increasing extracellular astrocyte-derived adenosine [PDF]
, 2012 Loss of sleep causes an increase in sleep drive and deficits in hippocampal-dependent memory. Both of these responses are thought to require activation of adenosine A1 receptors (adorA1Rs) and release of transmitter molecules including ATP, which is ...

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 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 ...
