Image analysis technique was applied to identify morphological changes of pellets from white-rot fungus Trametes versicolor on agitated submerged cultures during the production of exopolysaccharide (EPS) or ligninolytic enzymes. Batch tests with four different experimental conditions were carried out. Two different culture media were used, namely yeast medium or Trametes defined medium and the ...
An efficient intermittent ultrasonic treatment strategy was developed to improve laccase production from Trametes versicolor mycelia cultures. The optimized strategy consisted of exposing 2-day-old mycelia cultures to 5-min ultrasonic treatments for two times with a 12-h interval at the fixed ultrasonic power and frequency (120 W, 40 kHz). After 5 days of culture, this strategy produced the hig...
Aspergillus flavus is a well-known ubiquitous fungus able to contaminate both in pre- and postharvest period different feed and food commodities. During their growth, these fungi can synthesise aflatoxins, secondary metabolites highly hazardous for animal and human health. The requirement of products with low impact on the environment and on human health, able to control aflatoxin production, h...
Abstract Chinese medicine herbal extracts are ideal candidates to replace toxic industrial wood preservatives thanks their antifungal and nontoxic properties. To investigate the activity of medicines, in this study, Trametes versicolor fungi were selected as test strains evaluate properties Fructus Cnidii, Forsythiae, Radix Stemonae. The results show that Cnidii has a strong inhibitory effect a...
The phylogeny of Trametes and related genera was studied using molecular data from ribosomal markers (nLSU, ITS) and protein-coding genes (RPB1, RPB2, TEF1-alpha) and consequences for the taxonomy and nomenclature of this group were considered. Separate datasets with rDNA data only, single datasets for each of the protein-coding genes, and a combined five-marker dataset were analyzed. Molecular...
چکیده در این تحقیق، مقاومت به پوسیدگی فرآورده چند سازه چوب پلاستیک صنوبر دلتوئیدس تیمار شده با درصدهای مختلف نانواکسیدروی (2،1،0 و 3 درصد)، در برابر قارچ های عامل پوسیدگی سفید رنگین کمان (trametes versicolor) و پوسیدگی قهوه ای سرداب (coniophora puteana) بررسی گردید. بدین منظور آرد چوب صنوبر در دو سطح 60 و 70 درصد با پلی پروپیلن، 2 درصد عامل سازگارکننده mapp و 4 سطح نانواکسیدروی، در یک مخلوط کن...
This study was conducted to improve the pentachlorophenol (PCP) bioremediation ability of white-rot fungi in highly contaminated field soils by manipulating bioaugmentation variables. These were the dry weight percentage of fungal inoculum addition (31-175 g kg(-1)), PCP concentration (100-2137 mg kg(-1) PCP), fungal inoculum formulation, and time (1-7 wk). Five fungal isolates were used: the N...
