The present study reports a double enrichment cum selective isolation based protocol for successful isolation of lactic acid bacteria (LAB) from freshwater fish intestine where it exists in substantially lower population counts. The procedure involved enrichment of homogenized intestinal samples of freshwater fish in de Man, Rogosa and Sharpe (MRS) broth medium followed by further enrichment cu...

We present a numerical and experimental study of a guided-mode-resonance (GMR) device for detecting surface-bound light-absorbing thin films. The GMR device functions as an optical resonator at the wavelength strongly absorbed by the thin film. The GMR mode produces an evanescent field that results in enhanced optical absorption by the thin film. For a 100-nm-thick lossy thin film, the GMR devi...

We aimed to investigate the effects of job stress on biochemical variables schoolteachers before and after reduction strategies. In 2019, 200 (98 males, 102 females) in private fully aided higher secondary schools urban rural areas Vellore, India were enrolled study based principle consecutive sampling. Questionnaires used demographic characteristics occupational stress-related factors. Fasting...

background: breast milk is important for the overall well-being of infants. although lactation is relatively robust in the face of poor nutrition, the implication of poor nutrition on non-nutritive factors in breast milk is inconclusive. objective: this study was designed to find associations between nutritional and immune factors in maternal blood and breast milk with the aim to improve the ne...

The mesostructured materials MCM-41 and SBA-15 were studied as possible supports of bromocresol green (BG) dye impregnation for the ammonia gas detection because of their large surface area, high regenerative property, and high thermal stability. X-ray diffraction, transmission electron microscopy, scanning electron microscope, and N2 adsorption analysis were used to characterize the prepared m...

Bromocresol green (BCG) and bromophenol blue (BPB) in acidic and basic forms are used as dispersing agents to suspend multiple-walled carbon nanotubes (MWCNTs) into deionized water. The chemical structures of dye molecules are characterised by ultraviolet-visible-near infrared and nuclear magnetic resonance spectroscopies. The presence of MWCNTs in water is evidenced by transmission electron mi...

High concentrations of H(2)S in groundwater are commonly removed using Biological Trickling Filter (BTF) that contains high numbers of biofilm immobilized sulfur oxidizing bacteria (mainly Thiobacillus thiooxidans). BTF performance requires continuous monitoring of these bacteria at several sampling points. The Most Probable Number (MPN) technique is at the moment the method of choice to enumer...

B.1. Abstract A new optical sensing method for sensitive detection of amine vapors down to ppb levels is described. The sensor is based on the pH indicator Bromocresol green, adsorbed onto a silica sphere matrix. When the amines adsorb onto the matrix, the color changes from orange to blue. The color change is detected with a fiber optic spectrometer. Sensor performance is demonstrated for the ...
