Many classes of compounds have been shown to play an important role in the development flavour characteristics beer. This significantly influences its taste and sensory properties, thus affecting market performance. Despite intensive research aimed at unravelling precise mechanism regulation formation beer, current knowledge remains far from complete. Several reviews are available on general composition beer yeast metabolic pathways involved production volatile However, a limited amount work...
Background/Objectives: Globally, there has been an increase in the prevalence of anxiety and depression among university students, medical students are no exception. Medical especially susceptible to these mental health challenges, primarily due multifaceted stressors, which can significantly impact their academic achievements future career. There is a pressing need for comprehensive research that not only investigates but also explores strategies developing effective interventions support...
Catechol dioxygenases in microorganisms cleave catechol into cis-cis-muconic acid or 2-hydroxymuconic semialdehyde via the ortho- meta-pathways, respectively. The aim of this study was to purify, characterize, and predict template-based three-dimensional structure 1,2-dioxygenase (C12O) from indigenous Pseudomonas chlororaphis strain UFB2 (PcUFB2). Preliminary studies showed that PcUFB2 could degrade 40 ppm 2,4-dichlorophenol (2,4-DCP). crude cell extract 10.34 U/mL C12O activity with a...
Two indigenous ascomycetes fungi, Trichoderma lixii strain FLU1 (TlFLU1) and Talaromyces pinophilus FLU12 (TpFLU12), were isolated from benzo(b)fluoranthene-enriched activated sludge tested for bio-catalytically degrade fluoranthene as a sole carbon source. TlFLU1 TpFLU12 degraded 98 99% of 400 mg/L after 16 12 d incubation period, respectively. Degradation correlated with the upregulation expression ligninolytic enzymes. The GC-MS FTIR analysis degradation products suggest that is initiated...
Abstract The persistence and ubiquity of polycyclic aromatic hydrocarbons (PAHs) in the environment necessitate effective remediation strategies. Hence, this study investigated potential purified Laccases, Tl FLU1L Tp FLU12L, from two indigenous fungi Trichoderma lixii FLU1 ( FLU1) Talaromyces pinophilus FLU12 FLU12), respectively for oxidation detoxification anthracene. Anthracene was degraded with v max values 3.51 ± 0.06 mg/L/h 3.44 mg/L/h, K m 173.2 mg/L 73.3 0.07 by respectively....
Abstract Broad-spectrum biocatalysts enzymes, Laccases, have been implicated in the complete degradation of harmful pollutants into less-toxic compounds. In this study, two extracellularly produced Laccases were purified to homogeneity from different Ascomycetes spp. Trichoderma lixii FLU1 ( Tl FLU1) and Talaromyces pinophilus FLU12 Tp FLU12). The enzymes are monomeric units, with a molecular mass 44 kDa 68.7 for , respectively, on SDS-PAGE zymogram. It reveals distinct properties beyond...
Abstract The objective of this study was to evaluate the potential role gramineous weeds present near paddy fields as alternative hosts for Fusarium graminearum species complex (FGSC) that causes fusarium head blight (FHB) in rice. A total 142 weed samples were collected from 10 August October 2018 Jiangsu Province, China. Of 145 isolates seven isolated samples, F. asiaticum most abundant (86.9%), followed by fujikuroi (5.5%), proliferatum (2.8%), (2.1%), tricinctum (1.4%), acuminatum...
Aims: Aflatoxin B1 (AFB1) is a mycotoxin which known to frequently contaminate poorly stored food products destined for human consumption. This study was carried out investigate the potential activity of lactic acid fermentation in reducing AFB1 level fermented maize meal products. Methods and Results: Maize spiked with 60 μg g−1 fermented, or without starter culture, 4 days at 25°C. Unbound solution pH media were monitored daily. A significant decrease (P < 0·05) unbound observed (75%...
In 2017, 236 rice samples were collected from 42 counties in Jiangsu province, China, and analysed for Fusarium mycotoxins. Mycotoxin analyses showed that deoxynivalenol (DON), 3-acetyldeoxynivalenol (3-ADON), 15-acetyldeoxynivalenol (15-ADON), nivalenol (NIV), fusarenone X (FUS-X), zearalenone (ZEA), fumonisins (including FB 1 , 2 3 ), beauvericin (BEA) present unhusked samples. Regional differences mycotoxin contamination of attributed to precipitation during anthesis agricultural...
Members of Fusarium graminearum species complex (FGSC) are the major pathogens that cause head blight (FHB) in cereals worldwide. Symptoms FHB on rice, including dark staining or browning rice glumes, were recently observed Jiangsu Province, China. To improve our understanding involved, 201 FGSC isolates obtained from freshly harvested samples and identified by phylogenetic analyses. Among isolates, 196 F. asiaticum remaining 5 graminearum. Trichothecene chemotype chemical analyses showed...
The present study was performed to evaluate the effect of crop rotation on Fusarium mycotoxins and species in cereals Sichuan Province. A total 311 cereal samples were randomly collected analyzed from 2018 2019 results mycotoxin analysis showed that major trichothecene Province nivalenol (NIV) deoxynivalenol (DON), mean concentration trichothecenes (including NIV, fusarenone X [4ANIV], DON, 3-acetyldeoxynivalenol [3ADON], 15-acetyldeoxynivalenol [15ADON]) wheat significantly higher than...
A colloidal gold (ICS) test was developed for rapid detection of zearalenone (ZEN) in wheat samples.

Several weed species are known as alternative hosts of the Fusarium graminearum complex (FGSC), and their epidemiological significance in head blight (FHB) has been investigated; however, scant information is available regarding FGSC occurrence weeds near Chinese wheat fields. To evaluate potential role gramineous surrounding fields FHB, 306 isolates were obtained from 210 samples 2018 Jiangsu Province. Among them, 289 asiaticum, remainder F. graminearum.
