General description

Methyl red solution is an azo dye which turns to red when pH is below 4.4 (yellow pH < 6.2, orange pH 4.4-6.2). Some bacteria utilize glucose to form large amounts of acid with the result that the pH value of the medium falls distinct. Other species produce no or less free acid. This difference can be visualized by using methyl red. This test is used to differentiate enteric bacteria.

Application

Methyl red solution is a pH indicator dye recommended for detection of bacteria producing acid from glucose fermentation such as Enterobacteriaceae in various samples.

Highly active and enhanced photocatalytic silicon nanowire arrays.

Feng-Yun Wang et al.

Nanoscale, 3(8), 3269-3276 (2011-07-01)

Nanoporous and nonporous three-dimensional silicon nanowire arrays (SiNWAs) prepared with metal-assisted chemical etching method were investigated as photocatalysts in dye photodegradation systematically. In comparison with nonporous SiNWAs, nanoporous SiNWAs have higher surface area, larger pore volume, stronger light absorption and

Construction of an integrated enzyme system consisting azoreductase and glucose 1-dehydrogenase for dye removal.

Yuyi Yang et al.

Bioresource technology, 130, 517-521 (2013-01-17)

Azo dyes are toxic and carcinogenic and are often present in industrial effluents. In this research, azoreductase and glucose 1-dehydrogenase were coupled for both continuous generation of the cofactor NADH and azo dye removal. The results show that 85% maximum

Role of tyrosine 131 in the active site of paAzoR1, an azoreductase with specificity for the inflammatory bowel disease prodrug balsalazide.

Chan-Ju Wang et al.

Acta crystallographica. Section F, Structural biology and crystallization communications, 66(Pt 1), 2-7 (2010-01-09)

Azoreductase 1 from Pseudomonas aeruginosa strain PAO1 (paAzoR1) catalyses the activation of the prodrug balsalazide and reduces the azo dye methyl red using reduced nicotinamide adenine dinucleotide cofactor as an electron donor. To investigate the mechanism of the enzyme, a

A major focus of brain cancer research today is to translate understanding of glioma biology into advances in treatment, by exploring the potential of target therapy. Here we investigated the ability of three compounds belonging to the chemical class of

Influence of artificial mediators on yeast-based fuel cell performance.

Sofia Babanova et al.

Journal of bioscience and bioengineering, 112(4), 379-387 (2011-07-26)

Soluble artificial mediators are often applied to enhance the electron transfer from living cells to an anode in microbial fuel cells. Recently, we have demonstrated that the Candida melibiosica 2491 yeast strain possesses electrogenic properties and can be used as
