Vinasse is the dark-colored wastewater that is generated by bioethanol distilleries from feedstock molasses. The vinasse that is generated from molasses contains high amounts of pollutants, including phenolic compounds and melanoindin. The goal of this work was to study the expression of laccase genes in the Trametes hirsuta strain Bm-2, isolated in Yucatan, Mexico, in the presence of phenolic ...

Trametes hirsuta is an efficient lignin-degrading species due to its ability to produce laccase and Mn-dependent peroxidase. Agricultural residues represent prospective substrates for the bioconversion into fungal biomass and lignocellulolytic enzymes, but also they could be potential environmental pollutants. Evaluation of the potential of T. hirsuta to produce ligninolytic enzymes during soli...

The tremendous diversity of leaf shapes has caught the attention of naturalists for centuries. In addition to interspecific and intraspecific differences, leaf morphologies may differ in single plants according to age, a phenomenon known as heteroblasty. In Arabidopsis thaliana, the progression from the juvenile to the adult phase is characterized by increased leaf serration. A similar trend is...

Plants host at the contact zone with soil a distinctive root-associated bacterial microbiota believed to function in plant nutrition and health. We investigated the diversity of the root microbiota within a phylogenetic framework of hosts: three Arabidopsis thaliana ecotypes along with its sister species Arabidopsis halleri and Arabidopsis lyrata, as well as Cardamine hirsuta, which diverged fr...

Inflammation is a part of the non-specific immune response which occurs in reaction to any type of injury. Medicinal mushrooms have had application in various disorders including cancer, liver injuries, inflammation and diabetes. In the present study, the anti-inflammatory effects of the aqueous extracts of medicinal mushrooms (Fomes fomentarius, Ganoderma applanatum and T...

To search for secondary metabolites of Alnus hirsuta (Betulaceae), various chromatographic separations of the ethyl acetate soluble fraction of the stem bark of A. hirsuta led to the isolation of a new diarylheptanoid glycoside, (3R)-1,7-bis-(4-dihydroxyphenyl)-3-heptanol 3-O-beta-D-glucopyranosyl(1-->3)-beta-D-xylopyranoside (13) and twelve diarylheptanoid derivatives, namely, oregonin (1), ru...

Maximum entropy (Maxent) modeling was used to predict the potential climatic niches of three medicinally important Asclepiad species: Pentatropis spiralis, Tylophora hirsuta, and Vincetoxicum arnottianum. All three species are members of the Asclepiad plant family, yet they differ in ecological requirements, biogeographic importance, and conservation value. Occurrence data were collected from h...

Trametes hirsuta and a purified laccase from this organism were able to degrade triarylmethane, indigoid, azo, and anthraquinonic dyes. Initial decolorization velocities depended on the substituents on the phenolic rings of the dyes. Immobilization of the T. hirsuta laccase on alumina enhanced the thermal stabilities of the enzyme and its tolerance against some enzyme inhibitors, such as halide...
