Detection of Salmonella spp. in 344 samples of bean sprouts was attempted by pre-enriched in buffered peptone water (BPW) or lactose broth (LB) at 37 degrees C, followed by selective enrichments, selenite cystein broth (SCB) and Rappaport medium (RV) at 43 degrees C. Four selective media, bismuth sulphite agar (BSA), brilliant green agar (BGA), Salmonella-Shigella agar (SSA) and MacConkey agar ...

A simple and accurate cloud point-spectrophotometric method for determination of Mesalazine (MEZ) in pure form pharmaceutical formulations is proposed. The procedure based on the reaction with brilliant green dye (BG) forming a pale-yellow ion-pair complex after extracting Triton X-114 measured at 361 nm. experimental conditions phase separation were optimized. Beer’s law was obeyed range 0.3-3...

A three-phase study was conducted to compare Hektoen enteric agar (HE), Rambach agar (Ra), SM-ID medium (SM), xylose-lysine-Tergitol 4 agar (XLT4), novobiocin-brilliant green-glycerol-lactose agar (NBGL), and modified semisolid Rappaport-Vassiliadis medium (MSRV) for the recovery of nontyphoid salmonellae from stool specimens. After evaluation of the first two phases, which resulted in the elim...

The aim of the present study was the decolourisation of mixture of two dyes belonging to different groups by two Pseudomonas fluorescens strains (Sz6 and SDz3). Influence of different incubation conditions on decolourisation effectiveness was evaluated. Dyes used in the experiment were diazo Evans blue (EB) and triphenylmethane brilliant green (BG). Another goal of the experiment was the estima...

Mutative lactose fermentation of lactose negative strains of Klebsiella pneumoniae to the lactose positive condition has been reported by Henriksen (1950) and Cabelli and Pickett (1953). The latter workers also demonstrated that the ability to ferment lactose was associated with a faster growth rate and with a greater resistance to the bacteriostatic action of the dye brilliant green, to the in...

The sulfone derivatives of 1,2-bis(2-alkyl-6-phenyl-1-benzothiophen-3-yl)perfluorocyclopentene having various short alkyl chain substituents at reactive carbons were prepared and the effect of alkyl substitution on the fluorescence property of the closed-ring isomers was studied. Upon irradiation with ultraviolet (UV) light the derivatives exhibit a brilliant green fluorescence under irradiatio...
