Catalase, superoxide dismutase, and hemolysin in the virulence of Listeria monocytogenes
… Various concentrations of NaCl were added to growth media prior to bacterial inoculation. Most strains showed an increase in catalase, SOD, and LLO activities when propagated in media containing 428 mM NaCl (TSBS) followed by a decline in activities at greater NaCl concentrations. Potassium …

Inhibition of Hsp90 in Streptomyces coelicolor
… the presence of Hsp90 inhibitors, extracting the growth media, and subjecting the extractions to HPLC and MS analysis. It has been found that reproducibility is difficult to achieve. Since the genome of S. coelicolor has been sequenced, attention was turned to studying changes in mRNA expression …

The use of rockdust and composted materials as soil fertility amendments
… compost and various types of rockdust for use as growth media in comparison with a peat based control. Results showed that while greenwaste compost supported plant growth as well as the peat based media, no rockdust type increased plant growth beyond the yield in a greenwaste compost control. The …

Expression, Purification, and Characterization of the Mast Cell Proteases Chymase and Cathepsin G.
… of active enzyme into the <em>Pichia</em> growth media and increasing levels of enzyme were detected in the media for 5 days. Cells that secreted the highest levels of activity were selected by kinetic assay. Active chymase was purified from the culture media with a 22% yield of activity by …

Genetic Manipulation and Characterization of Solvent-Producing Clostridia
… CSL has been found to support good bacterial growth while allowing a level of solvent production approaching that of complex, more expensive clostridial growth media. When used in combination with C. beijerinckii, BA101, this newly developed medium holds promise to increase the …

Study of the Effect of BiOWiSH Aqua on Simultaneous Nitrification and Denitrification in a Membrane Aerated Bioreactor
… The mean nitrogen removal rate observed when the media in the system reached steady state was 0.39 mg-N/L-hr. with a carbon to nitrogen (C: N) ratio of 12:1. The only increase in the nitrogen removal rate observed was when the C: N ratio was doubled to 24:1 and the nitrogen removal rate increased …

Effects of combined high hydrostatic pressure and dense phase carbon dioxide treatments on inactivation of enzymes, microorganisms and sensory properties of different products
… feijoa, inactivation of microorganisms in their growth media and sensory properties of treated feijoa products. The changes in pure PPO secondary structure, size and inactivation kinetics were studied. Feijoa puree, pure mushroom PPO (E.C.1.14.18.1) and microorganisms (Escherichia coli, Bacillus …

Dynamics of biofilm processes in an annular reactor
… Nutrients, glucose and in some cases a synthetic growth media, were added to the reactor to provide the necessary mineral, energy and carbon requirements for microbial growth. Material balance relationships are developed which are useful in analyzing the interrelated processes contributing top …

Investigating the role of a yeast membrane protein, HSP30 in tolerance to ethanol stress
… cerevisiae is able to grow and remain viable in growth media containing ethanol concentrations as high as 19.8% (w/v), a level that is toxic to many other microorganisms. Since production of ethanol is a normal event in the growth cycyle of S. cerevisiae, this organisms has evolved a number of …
