The quantification of exogenous lactobacilli in faecal samples is frequently required for the evaluation of the intestinal colonization by probiotic bacteria. In this study, a selective and differential medium, designated LPSM, was developed for the culture of exogenous Lactobacillus plantarum. In quantitative assays, LPSM showed a sensitivity similar to those of enriched and Lactobacillus-adap...

The paper presents research results on the colorimetric behavior of impregnated fibrous chemisorbents (IFCS) basic gases with visual identification dynamic absorption capacity “response” moment (IFCS-I) during ammonia. Chemisorbents were obtained by impregnation carriers polybasic hydroxyl acid aqueous solutions adding acid-base indicators (Ind). IFCS-I based oxyethylenediphosphonic (IFCS-OEDPA...

Natural phenolic antioxidants are extensively studied compounds due to their positive health effect and wide distribution in human diets. The simultaneous occurrence samples requires selective methods for determination. Electrochemical sensor based on the polyaminobenzene sulfonic acid functionalized single-walled carbon nanotubes (f-SWCNT) electropolymerized bromocresol purple has been develop...

Kuantum noktalar (QDs) sahip oldukları benzersiz optik ve elektronik özellikleri ile son yıllarda birçok 
 farklı teknolojik alanda popüler hale gelmişlerdir. Bu durum QD'lar organik bileşiklerin etkileşimine olan ilgiyi arttırmaktadır. çalışmada bu ilgiye temel alarak, CdSeTe Brom Krezol Moru (BCP)
 kloroform içerisinde oda sıcaklığın da etkileşimini QDs/BCP yapısının spektroskopik o...

The direct deposition of polyethyleneimine (PEI), a weak polycation with large content amino groups, onto sand fractions different sizes (F70, F100, F200, and F355), resulted in versatile core-shell sorbents for water cleaning. Herein, PEI the polyanion poly(acrylic acid) (PAA) were directly precipitated as an nonstoichiometric polyelectrolyte complex ([PEI]:[PAA] = 2:1) surface followed by cro...

Two simple, accurate and sensitive spectrophotometric methods were developed for the determination of ticlabendazole in bulk and pharmaceutical formulation. These methods were based on the formation of ion-pair association complex (1:1) with bromocresol purple (BCP) and bromophenol blue (BPB). The coloured products were extracted into chloroform and measured spectrophotometrically at 420 nm. Li...

Bromocresol purple-milk solids-glucose medium, proposed by Fischer and Kane in 1971 (Mycopathol. Mycol. Appl. 43:169-180, 1971) as an aid in the rapid determination of Trichophyton rubrum and Trichophyton mentagrophytes, was evaluated across a wide range of isolates to determine its accuracy and efficacy in the clinical laboratory. Results showed that it facilitated accurate determination of ty...

A gas diffusion FIA method for determination of total CO(2) in beer and in soft drinks is described. The composition of the acceptor stream for diffused carbon dioxide is critical. Bromocresol purple has been selecled among a large number of tested pH indicators and if the detection is made at a wavelength of 430 nm, stable baseline conditions and positive deflections of the resulting FIA peaks...

Curing is the first process of skin treatment mainly using sodium chloride salt to prevent its decay. At soaking step tannery, effluents will be discharged environment, which contains ion, negatively affect our environment. Therefore, it should either treated or reused so that can help reduce amount ion effluent environment and cost pickling. This study focused on recycling curing for sheepskin...

Guanine propionate was isolated as described previously (1). 7-Methylguanine and N*-methylguanine were gifts from Dr. Gertrude Elion, Wellcome Research Laboratories (Tuckahoe, New York). Phosphate was determined according to the method of Fiske and SubbaRow (2). The orcinol determination of pentose was carried out by the procedure of Kerr et al. (3). The Pauly reaction was run according to the ...
