Essential oils extracted from nine different plants exhibit differential effects on skin antioxidation and elasticity.

Essential oils derived from plants are major ingredients in the medical and cosmetic industry. Here, we evaluated nine types of plant essential oils to identify potential candidates with antioxidant and elasticity-enhancing properties. Seven essential oils showed at least 10% radical scavenging activity at the highest concentration.

Seven Unrecorded Indigenous Fungi from Mudeungsan National Park in Korea.

Fungi act as important decomposers in the forest environment. They recycle essential nutrients, promote plant growth through mycorrhizal relationships, and act as food for small animals. Samples of 265 indigenous fungal species were collected from Mudeungsan National Park in 2020.

Two Unrecorded Species Isolated from Marine Substrates in Korea with Eight New Combinations ( and ).

Although Sacc. has previously been considered a sexual morph of species on the basis of phylogenetic, morphological, and ecological diagnoses, a recent study delimited these as different species. Recently, 14 species, including eight new species, of marine have been reported from Korea.

Inhibitory effects and underlying mechanisms of essential oil on melanogenesis in the B16F10 cell line.

The present study investigated the anti‑melanogenic activity of 10 essential oils using the B16F10 cell model. Initially, a wide range of concentrations of these essential oils were screened in order to determine their toxicity levels. The assigned non‑toxic concentrations of the tested essential oils were then used to evaluate their effects on melanogenesis.

Optimization of Fungal Enzyme Production by KUC1716 through Surfactant-Induced Morphological Changes.

The morphological optimization of was carried out using several surfactants to achieve increased cellulase production. Addition of the surfactants to the culture medium successfully modified the fungal morphology from an aggregated form to a dispersed form. Optimization of the fungal morphology increased cellulase activity up to 177%.

Phylogenetic Identification of Korean spp. and the First Report of 3 Species: , , and .

is a cosmopolitan genus of agaric fungi and consists of ~300 species. In Korea, represents common saprobic mushrooms, and 12 species have been reported in Korea. Several specimens were collected in Korea between 2008 and 2015.

Decolorizing an anthraquinone dye by : Intra-species characterization.

Remazol brilliant blue R (RBBR) is an anthraquinone dye derived from anthracene that is decolorized by a white rot fungus, . Interestingly, produces two phenomena of yellowish and pinkish colors during the degradation of RBBR. Here, we characterized the decolorization of RBBR by .

Isolation and analysis of the enzymatic properties of thermophilic fungi from compost.

To the best of our knowledge, this is the first report on thermophilic fungi isolated in Korea. Three species of thermophiles were isolated from compost and were identified as Myriococcum thermophilum, Thermoascus aurantiacus, and Thermomyces lanuginosus. They can grow at temperatures above 50℃ and produce high levels of cellulolytic and xylanolytic enzymes at high temperatures.

The antioxidant properties of solid-culture extracts of basidiomycetous fungi.

Current studies of the antioxidant activity of fungal resources are mainly focused on the fruiting bodies of edible mushrooms. To access the potential of basidiomycetes in culture-state applications, extracts of solid cultures of 83 basidiomycetous fungi newly isolated from woody materials were prepared at the same concentration (10 mg/ml), and their antioxidant activities were measured using ABTS (2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid) and DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging assays. Among the basidiomycetes tested, Cryptoporus volvatus, Daedalea dickinsii, Gloeophyllum abietinum, G.

Extraction of chromium, copper, and arsenic from CCA-treated wood by using wood vinegar.

In the present study, wood vinegar was used to extract chromium, copper, and arsenic from chromated copper arsenate (CCA)-treated wood. The extraction efficiency for CCA elements was evaluated using various concentrations of wood vinegar, extraction temperatures, and extraction periods. The extraction efficiency for CCA elements increased with increasing the concentration of wood vinegar and the extraction conditions, resulting in maximal removal rate of copper (95.
