Sequencing and description of the genome of a strain of isolated from a patient infected with COVID-19 at Hospital Regional No.1 de Charo, Michoacán, México.

is a bacterial genus that can be found in various environments, such as water, soil, and clinical samples. Due to their high genetic and phenotypic diversity, it is difficult to properly identify and classify all isolates. The COVID-19 pandemic caused an increase in nosocomial infections, which played a major role in the high mortality rate among patients in intensive care.

Corn stover induces extracellular laccase activity in Didymosphaeria sp. (syn. = Paraconiothyrium sp.) and exhibits increased in vitro ruminal digestibility when treated with this fungal species.

Fungi can improve stover digestibility due to their ability to secrete oxidative enzymes that depolymerize lignin, allowing the rumen microorganisms to access the polysaccharides of the plant cell wall. Some ascomycetes have shown good delignification capability; however, they have been scarcely evaluated for their ability to improve corn stover (CS) ruminal digestibility. We evaluated the laccase induction by CS of the CMU-196 strain of the ascomycete fungus Didymosphaeria sp.

Identification and characterization of the biotechnological potential of a wild strain of Paraconiothyrium sp.

The isolation and characterization of fungal strains from poorly described taxa allows undercover attributes of their basic biology useful for biotechnology. Here, a wild fungal strain (CMU-196) from recently described Paraconiothyrium genus was analyzed. CMU-196 was identified as Paraconiothyrium brasiliense by phylogenetic analysis of the rDNA internal transcribed spacer region (ITS).

Characterization of ligninolytic enzyme production in white-rot wild fungal strains suitable for kraft pulp bleaching.

Fungal strains identified by phylogenetic analysis of the ITS rDNA region as (CMU-TA01), (CMU-84/13), and sp. (CMU-47/13) are able to grow on and bleach kraft pulp (KP) in a simple solid-state fermentation (SSF) assay conducted in Petri dishes. Kappa number reductions obtained with sp.

Typing and selection of wild strains of Trichoderma spp. producers of extracellular laccase.

Using the ITS region and the gene tef1, 23 strains of the genus Trichoderma were identified as belonging to the species T. harzianum (n = 14), T. olivascens (n = 1), T.
