mycophenolic acid is a secondary extracellular metabolite of penicillium strains with numerous pharmaceutical properties such as antibiotic and immunosuppressive uses. the aim of this work is the survey of the effect of phenylglyoxal and n-ethylmaleimide concentration in culture medium on mycophenolic acid production by penicillium brevi-compactum atcc16024 was investigated. batch submerged fer...

A cross-sectional telephone survey (n = 2,332) was performed to better understand the drinking water consumption patterns among residents in Waterloo Region, Ontario, Canada. We investigated the daily volume of water consumed (including tap and bottled) and factors related to that consumption. In addition, we investigated the daily volume of cold tap water consumed by those respondents who cons...

The objective of this research was to investigate the influence of the over-expression of recombinant interferon-g during high cell density cultivation on cellular characteristics of recombinant E. coli. Batch and fed-batch culture techniques were employed to grow Escherichia coli BL21 for production of human gamma-interferon in pET expression system. Final cell densities in batch and fed-batch...

Hydrocarbons are prone to bacterial and fungal contamination. Bacteria and fungi live and proliferate in water droplets within the fuels and on surfaces surrounding them. This can cause corrosion in oil exploration and production, clogging of fuel lines in aviation and higher emissions in diesel combustion engines to state few examples. State-of-the-art is the addition of biocides to fuels, whi...

A fuel cell is essentially a compact electrochemical “factory” that takes fuel as input and produces electricity as output (see fig. 1). Like a factory, a fuel cell will continue to churn out product (electricity) as long as raw material (fuel) is supplied. This is the key difference between a fuel cell and a battery. While both rely on electrochemistry to work their magic, a fuel cell is not c...

integrated assessment of water resources systems, as one of the iwrm basic steps, is the most important stage in the process of planning and implementing water resources management. water accounting frameworks have been introduced for organizing water data and combining them with economic data to come up with effective strategies towards greater productivity with maintaining or improving enviro...
