Continuous and static fermentation of glucose to ethanol by immobilized Saccharomyces cerevisiae cells of different ages.

Glucose was converted to ethanol by calcium-alginate-entrapped Saccharomyces cerevisiae NRRL Y-2034 cells that were 24, 48, 72, and 96 h old in continuous-flow and static repeated-batch fermentors. In general, older yeast cells were more efficient than younger ones. In most cases, the continuous fermentations were better than the static ones in producing maximum ethanol yields (5.11 g/10 g of g...

biodegradation of different concentration of dye (congo red dye) by using green and blue green algae

releasing of textile dye effluents into general water bodies is a major environmental and healthproblem. color removal, in particular, has recently become of major scientific interest, as indicated by themultitude of related research reports. during the past two decades, several physico-chemical decolorizationtechniques have been reported, few, however, have been accepted by the textile industr...

Nanoscopy of bacterial cells immobilized by holographic optical tweezers

Imaging non-adherent cells by super-resolution far-field fluorescence microscopy is currently not possible because of their rapid movement while in suspension. Holographic optical tweezers (HOTs) enable the ability to freely control the number and position of optical traps, thus facilitating the unrestricted manipulation of cells in a volume around the focal plane. Here we show that immobilizin...

Free and immobilized glucose isomerase from Streptomyces phaeochromogenes.

Properties were determined of the glucose isomerase from Streptomyces phaeochromogenes NRRL B-3559. The enzyme exhibited a temperature optimum of 80 C and a pH optimum of about 8. The effect of various buffers on activity of the enzyme and the optimum pH were studied. Michaelis constants for glucose and Mg(2+) were 0.25 and 0.025 m, respectively. Co(2+) enhanced enzyme activity. A functional po...

Decolorization of Malachite Green Dye Solution by Bacterial Biodegradation

Malachite green dye is widely used in food and textile industries for various purposes and also used as biocide in the aquaculture industry to control fungal attacks and protozoan infections. Surface and ground water is contaminated by dyes due to discharge of untreated wastewater from industries. The presence of malachite green in water causes serious health effects such as mutagenesis, re...
