Bacteria moving in response to chemical attractants are subject to noise from the environment in addition to that within the cells.
Environmental noise is observed typically through fluctuations in the concentrations of the chemoattractant. Interactions between two
or more sources of noise may upset the chemotactic motility of the cells. This possibility is investigated here for Escherichia coli
through a pair of conditions derived earlier. These conditions relate the tumbling time, the sensing

Xylitol production from lactose was investigated by a three step biotransformations series that were: (1) breakdown of lactose to Darabitol
by Kluyveromyces lactis NBRC 1903, (2) oxidation of Darabitol to D-xylulose by Gluconobacter oxydans NBRC 3172, and
(3) reduction of D-xylulose to xylitol by Candida shehatae IAM 12953 in the presence of a high concentration ethanol or by cell free
sorbitol dehydrogenase. Overall production rate and overall fractional yield of xylitol from lactose were 1.69

Microbial fuel cell technology is a new type of renewable and sustainable technology for electricity generation since it recovers energy from renewable materials that can be difficult to dispose of, such as organic wastes and wastewaters. In the present contribution we demonstrated electricity production by beer brewery wastewater, sugar industry wastewater, dairy wastewater, municipal wastewater and paper industry wastewater. Up to 14.92 mA current and 90.23% COD removal was achieved in 10 days

Lovastatin production using pellets of Aspergillus terreus was investigated in an airlift reactor. A fuzzy system has been developed for predicting the lovastatin productivity. Analysis of the effect of dilution rate and biomass concentration on the productivity of lovastatin was carried out and hence these were taken as inputs for the fuzzy system. The rule base has been developed using the conceptions of developmental processes in lovastatin production. The fuzzy system has been constructed on

This article reviews the fundamentals of supercritical fluid (SCF) science and moves on to the biotechnological applications of them e.g. removal of biostatic agents from fermentation broths, SCF disruption of microorganisms, destruction of industrial waste, the gas-antisolvent crystallization and micron-size particle formation. Also gaining ground is enzymatic catalysis in supercritical carbon dioxide (SC-CO2), which offers the possibility of integrated synthesis product recovery processes. The
