Impact of carboxymethylcellulose on morphology and antibiotic production by Streptomyces hygroscopicus
(Current Microbiology, 2008)
A chemically defined media consisting of carboxymethylcellulose (CMC) was developed to maximize the production of antibiotics, hexaene H-85 and azalomycine, by Streptomyces hygroscopicus CH-7. The production of antibiotics ...
The contributions of high- and low altitude emission sources to the near ground concentrations of air pollutants
(Elsevier Science Inc, New York, 2008)
The scale of transport through the atmosphere depends on the effective height of an emission source, the meteorological conditions and the physico-chemical characteristics of the pollutants. Atmospheric surface temperature ...
Trans- and cis-resveratrol concentration in wines produced in Serbia / Koncentracija trans- i cis-rezveratrola u vinima proizvedenim u Srbiji
(Serbian Chemical Soc, Belgrade, 2008)
Resveratrol, which occurs in two isomeric forms, trans and cis, is a phytoalexin with numerous pharmacological activities, such as anti-cancer, antiviral, neuroprotective and anti-aging. Red wine is the main source of the ...
Characterization of platinum deposited on carbon hollow fibers / carbon cryogel composites
(Journal of Optoelectronics and Advanced Materials, 2008)
Platinum supported on high surface area carbon material is one of the most intensively studied catalysts. However, physicochemical characteristics and surface chemistry of carbon influence properties of the support itself ...
The electrochemical behavior of commercial clarithromycin and spectroscopic detection of its structural changes
(Pleiades Publishing Inc, Moscow, 2008)
The aim of the present study was to examine the behavior of commercial clarithromycin, Clathrocyn (R), comparing to the results previously obtained using pure clarithromycin under the same experimental conditions. The study ...
