Medicinal plants constitute a potential source of bioactive molecules which can provide new antimicrobial agents. This study aims to evaluate the antibacterial activity against multidrug resistant bacteria associated with skin infections and screen phytochemical composition Thymelaea hirsuta Anacyclus pyrethrum from Algeria. For this purpose, four multi-drug were isolated pus samples compared S...

The aim of this electrochemical study was to ascertain which position of hydroxy groups on a benzene ring provides electroactive products after enzymatic oxidation by laccase originating from the Trametes versicolor mushroom, exhibiting intense redox signals that are exploitable for their amperometric determination. The electrochemical properties of phenol together with all isomers of benzenedi...

This study examined the feasibility of using Trametes sp. grown under drought conditions to catalyze the covalent cross-linking of ferulated arabinoxylans. The rate of polymerization of ferulated arabinoxylans solutions at 0.5% (w/v) was dose dependent on the laccase concentration in the system. Above 1.2 nkat laccase/mg ferulated arabinoxylan, the rate of cross-linking reached a plateau, sugge...

The white-rot fungi produce wide range of extracellular enzymes (especially ligninolytic enzymes) and they can degrade complicated and difficult degradable compounds. An immobilization of enzymes causes their stability, reusability and cheapness, so they could be effectively used in biotechnologies and other branches. In this work we focused on the optimization of isolation procedure namely pre...

Basidiocarps of Trametes versicolor with an epiphytic flora (including Trebouxia sp.) collected from north-central Rhode Island were incubated in an atmosphere of C labeled CO2 for 6 hours. Using autoradiography, the location of the fixed CO2 was determined at 6h, 12h, 24h, 48h, 96h, and 192h. The fixed C was recorded in the epiphytic algae after 6h, and at all subsequent times. After 192h the ...

A revision of the genus Mitragyna (Rubiaceae) in Thailand is reported. Four species, i.e. M. diversifolia, hirsuta, rotundifolia, and speciosa are described this taxonomic treatment. summary history, detailed morphological descriptions, distributions, ecology, phenology, vernacular names, uses, IUCN conservation status, specimens examined, photographs a key to species proposed. Two names lectot...
