sp. nov., a novel black yeast isolated from the gut of amphipods in Thailand.

The genus is polymorphic, able to transition between yeast, hyphal and pseudohyphal forms. Species of the genus are ubiquitous fungi that are distributed in various environments around the world. During a survey of fungal diversity in the gut of amphipods ( and undescribed Dogielinotid amphipods) from the Amphawa estuary, Samut Songkhram province, Thailand, five black yeast strains (DMKU-MG01, DMKU-MG07, DMKU-MG08, DMKU-HG10 and DMKU-FG04) were identified as representing a novel taxon on the basis of a combination of morphological and molecular phylogenetic features.

Dual Activation of Peroxymonosulfate Using MnFeO/g-CN and Visible Light for the Efficient Degradation of Steroid Hormones: Performance, Mechanisms, and Environmental Impacts.

Single activation of peroxymonosulfate (PMS) in a homogeneous system is sometimes insufficient for producing reactive oxygen species (ROS) for water treatment applications. In this work, manganese spinel ferrite and graphitic carbon nitride (MnFeO/g-CN; MnF) were successfully used as an activator for PMS under visible light irradiation to remove the four-most-detected-hormone-contaminated water under different environmental conditions. The incorporation of g-CN in the nanocomposites led to material enhancements, including increased crystallinity, reduced particle agglomeration, amplified magnetism, improved recyclability, and increased active surface area, thereby facilitating the PMS activation and electron transfer processes.

Light Regulation of Two New Manganese Peroxidase-Encoding Genes in KU-RNW027.

To better understand the light regulation of ligninolytic systems in KU-RNW027, ligninolytic enzymes-encoding genes were identified and analyzed to determine their transcriptional regulatory elements. Elements of light regulation were investigated in submerged culture. Three ligninolytic enzyme-encoding genes, , , and , were found.

Two Manganese Peroxidases and a Laccase of KU-RNW027 with Novel Properties for Dye and Pharmaceutical Product Degradation in Redox Mediator-Free System.

Two manganese peroxidases (MnPs), MnP1 and MnP2, and a laccase, Lac1, were purified from KU-RNW027. Both MnPs showed high stability in organic solvents which triggered their activities. Metal ions activated both MnPs at certain concentrations.

Morphological Characteristic Regulation of Ligninolytic Enzyme Produced by .

A newly isolated white rot fungal strain KU-RNW027 was identified as , based on an analysis of its morphological characteristics and phylogenetic data. Aeration and fungal morphology were important factors which drove strain KU-RNW027 to secrete two different ligninolytic enzymes as manganese peroxidase (MnP) and laccase. Highest activities of MnP and laccase were obtained in a continuous shaking culture at 8 and 47 times higher, respectively, than under static conditions.
