Bioassay and gene expression experiments were conducted in order to evaluate the growth and physiology of Prorocentrum minimum isolated from a eutrophic coastal water in response to tannic acid. In the bioassay experiments, variations in abundance, chlorophyll (chl) a concentration, maximum fluorescence (in vivo Fm), and photosynthetic efficiency (Fv/Fm) were measured over the course of a seven...

the research focused to evaluate physical, chemical, and sensory properties of raw, blanched, and 2, 4, and 6% osmotically salt treated mandarin (citrus reticulata) peel powder. the yields of mandarin peel powder (mpp) were found in the range of 29.1 to 30.4% (db) for different treatments, which were not significantly different. the bulk density and solubility were found in the range of 1,267-1...

Total urinary protein is rapidly precipitated at room temperature by tannic acid. The tannic acid/protein precipitate, dissolved in aqueous triethanolamine/ferric chloride solution, gives a purple-violet color of high absorptivity. Absorbance at 510 nm is linearly related to concentration from 0.05 to 1.50 A for a protein content of 0.05 to 1.50 g/liter, and less than 5 mg/liter can be detected...

Abstract The influence of biomass cellulosic content on biochar nanopore structure and adsorption capacity in aqueous phase was scarcely reported. Commercial cellulose (100% cellulose), oil palm frond (39.5% kernel shell (20.5% cellulose) were pyrolyzed AT 630 °C, characterized tested for the iodine organic contaminants. external surface area average pore size increased with content, where comm...

background and objectives: tannins are toxic polyphenols that either bind and precipitate or condense proteins. the high tannin content of some plants is the preliminary limitation of using them as a ruminant feed. so, the aim of this study was the isolation and characterization of tannic acid degrading bacterial strains from goat feces before and after feeding on pis- tachio-soft hulls as tann...

Effects of tannic acid on hatching of Heterodera glycines eggs were determined in vitro using three batches of eggs obtained from greenhouse cultures in Florida or from naturally infested field soil in Minnesota. A quadratic model fits the percentage egg hatch. Hatch increased with increasing tannic acid concentrations from 0 to about 39 mg/liter, then declined with further increases in concent...

Purpose: Increasing evidence suggests that interaction between the chemoattractant CXCL12/stromal cell-derived factor-1 and its receptor CXCR4 plays a pivotal role in the metastasis of various tumors. Our previous studies showed that multi-component Chinese herbal medicines inhibited the effects of CXCL12/CXCR4. As a result of sequential chromatographic fractionation of one herbal medicine ingr...

The antimicrobial effect of tannic acid and raw material of Acacia nilotica fruits and leaves (tannin-rich plant) on Clostridium perfringens were comparatively evaluated. Different concentrations) 10 mg to 10 μg/ml)of tannic acid; fruits, and leaves were tested on Cl. perfringens. The obtained results revealed that the minimum inhibitory concentrations were 156, 75 and 100 μg/ml for tannic acid...

Abstract Background There is a need for the screening more effective, affordable and readily available antimicrobial substances from local medicinal plants or herbs as pathogenic bacteria are developing resistance to common antibiotics. Guava ( Psidium guajava L.) has activities it easily accessible populace in tropical region. Antimicrobial properties of guava extracts attributed presence diff...
