This work compares two electrode materials used to mineralize phenol contained in waste waters. Two disks covered with either boron doped diamond (BDD) or PbO2 were used as anodes in a one compartment flow cell under the same hydrodynamic conditions. Efficiencies of galvanostatic electrolyses are compared on the basis of measurements of Total Organic Carbon (TOC) and Chemical Oxygen Demand (COD...

When Penicillium simplicissimum is grown on veratryl alcohol, anisyl alcohol, or 4-(methoxymethyl)phenol, an intracellular covalent flavin-containing vanillyl-alcohol oxidase is induced. The induction is highest (up to 5% of total protein) during the growth phase. In addition to vanillyl-alcohol oxidase, an intracellular catalase-peroxidase is induced. Induction of vanillyl-alcohol oxidase in P...

It has been established that the well-known deproteinizing action of hot 45% aqueous phenol on whole cells or isolated and purified endotoxin of Serratia marcescens 08 is caused by the cleavage of a phenol-sensitive linkage within the lipid moiety. As a result of this degradation, both the lipopolysaccharide and simple protein fragments retained a part of the lipid moiety. Although not proceedi...

In cells of Rhodococcus opacus GM-14, GM-29, and 1CP, the contents of branched (10-methyl) fatty acids increased from 3% to 15 to 34% of the total fatty acids when the cells were grown on benzene, phenol, 4-chlorophenol, chlorobenzene, or toluene as the sole source of carbon and energy, in comparison with cells grown on fructose. In addition, the content of trans-hexadecenoic acid increased fro...

as sorgoleone (Einhellig and Souza, 1992; Einhellig et al., 1993; Weston et al., 1997) and phenolic acids (BenThe total phenol pool (kg ha21) of the aerial parts and roots of Hammouda et al., 1995; De Raissac et al., 1998) to the sorghum (Sorghum bicolor L. cv. CE145266) crops and their relationships to dry matter and total phenol concentrations (g kg21) were soil by decomposing crop residues (...

Euphorbia resinifiera is a well-known medicinal plant used by the Moroccans to treat several diseases. This study evaluated influence of extraction solvents polarities (methanol, aqueous/methanol (3:7), and distilled water) on polyphenols flavonoids contents extracts obtained three methods: infusion, maceration sonication, as well their antioxidant activity. The results revealed that water extr...
