The exact nature and function of the metachromatic (volutin) granules seen in many microorganisms is still a matter of conjecture although polymetaphosphates (polymers of highenergy anhydride-linked phosphates) are a known constituent. The object of this paper is to re-examine volutin as a cytological entity, and to present a working hypothesis on the mechanism of formation of this substance. T...

It is well established that defined microorganisms may cause cancer. Basic, molecular mechanisms are known and might contribute to innovative prophylaxis or treatment strategies, e.g. vaccination. The ability of defined attenuated microorganisms to cause tumour regression is well known, however, the mode of action mostly remained unknown. It is generally believed that e.g. bacteria (or their pr...

This article is an introduction to the use of NMR for the investigation of microbial physiology and metabolism. NMR parameters which determine the sensitivity and resolving power of the method are reviewed. A broad survey of current applications follows. Qualitative uses are described first; they include compound identification and localisation. Quantitative aspects, such as pH, concentration a...

The aim of this study was to apply loess balls containing effective microorganisms (EM) to the remediation of contaminated harbor sediments, and to thereby elucidate the functions of EM in remediation. Changes in physicochemical, biochemical, and microbiological parameters were measured to monitor the remediation process at a laboratory scale. Treatment with high concentrations of EM stock cult...

ent ways to produce Coombs serum are described with little or no attempt to define how important they are in the overall scheme of human blood and serum groups. But perhaps because this is a reference book it is more important to detail everything than to discuss those areas that the authors deem important. Some subjects, the Lewis, the I, i, and the leukocyte groups, for example, are discussed...

In this study presence of various kinds of microorganisms in kitchen sponges were studied. Additionally effects of regular dish washing liquid on Escherichia coli ATCC 8739 and Salmonella typhimurium ATCC 13311 were investigated under laboratory conditions in kitchen sponges with or without food residue. The sponges involved in daily use in households were samples were analysed for the presence...

BACKGROUND Butanol is an industrial commodity and also considered to be a more promising gasoline substitute compared to ethanol. Renewed attention has been paid to solvents (acetone, butanol and ethanol) production from the renewable and inexpensive substrates, for example, lignocellulose, on account of the depletion of oil resources, increasing gasoline prices and deteriorating environment. L...

Different modified atmosphere conditions with various CO2 concentrations on microbial load (psychrophile, mesophile aerobic and anaerobic bacteria) and physico-chemical properties of barramundi (Lates  calcarifer Bloch) fillets stored at 8°C were compared to determine the best packaging conditions. The gas conditions evaluated were 100% CO2 (M1), 75% CO2/25% N2 (M2), 50% CO2/50% N2 (M3), 25% CO...
