Abstract This study identified a common Streptomyces sp. (MN262194) from forest soil as an efficient decolorizer of triphenylmethane (TPM) dyes. Partial 16S rRNA sequencing the isolate possibly bacillaris (similarity 99.32%). Live and dead cells were applied to decolorize Malachite Green (MG), Methyl Violet (MV), Crystal (CV), Cotton Blue (CB). The decolorization efficacy for both cell types wa...

Reducing amyloid-β (Aβ) accumulation is a promising strategy for developing Alzheimer's Disease (AD) therapeutics. We recently reported that a triphenylmethane food dye analog, Brilliant Blue G (BBG), is a dose-dependent modulator of in vitro amyloid-β aggregation and cytotoxicity in cell-based assays. Following up on this recent work, we sought to further evaluate this novel modulator in a the...

Drug residues are considered environmental contaminants, and their occurrence has recently become a matter of concern. Analytical methods and monitoring systems are therefore required to control the continuous input of these drug residues into the environment. This article presents a suitable HPLC-ESI-MS/MS method for the simultaneous extraction, detection and quantification of residues of 13 d...

OBJECTIVE This study investigated the association of yeast species with improved aerobic stability of total mixed ration (TMR) silages with prolonged ensiling, and clarified the characteristics of yeast species and their role during aerobic deterioration. METHODS Whole crop corn (WCC) silages and TMR silages formulated with WCC were ensiled for 7, 14, 28, and 56 d and used for an aerobic stab...

A quantitative and confirmatory method for detecting the presence of triphenylmethane dyes in shrimp muscle using ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) a quick, easy, cheap, effective, rugged safe (QuEChERS) extraction approach was validated. The exhibited linearity selectivity coefficient determination (R2) higher than 0.95 all studied analytes. Li...

Excited state dynamics of S2 and S1 states for a series of TPM dyes, pyrogallol red (PGR), bromopyrogallol red (Br-PGR) and aurin tricarboxylic acid (ATC), have been monitored by using ultrafast transient absorption and fluorescence up-conversion techniques. Optical absorption studies indicate that all the TPM dyes exist as keto-enol tautomers depending upon the pH of the solution. Interestingl...
