Many free-living saprobic fungi are nature recruited organisms for the degradation of wastes, ranging from lignocellulose biomass to organic/inorganic chemicals, aided by their production enzymes. In this study, fungal strains were isolated contaminated crude-oil fields in Nigeria. The dominant selected each site and identified as Aspergillus oryzae Mucor irregularis based on morphological molecular characterization, with percentage incidences 56.67% 66.70%, respectively. Selected...

Fungal spores dispersed in the atmosphere may become cause of different pathological conditions and allergies for human beings. A number studies have been performed to analyze diversity airborne fungi environments worldwide, particular many urban areas China. We investigated, first time, diversity, concentration distribution Tianjin city. sampled 8 outdoor environments, using open plate method, during a whole winter season. Isolated were identified by morphological molecular analysis....

Over the years, practice of agriculture has transformed from era traditional to that intensive in bid boost production index will satisfy food needs globally growing population. However, continuous and exaggerated use chemical fertilizers pesticides resulted major adverse impacts on environmental safety, whereas most techniques for reclamation natural soil nutrients, including shifting cultivation polyculture, are no longer attractive measures land rejuvenation. There is, therefore, need...

Fungi are usually involved in degradation/deterioration of many anthropogenic wastes due to their verse enzyme secretions and adaptive capabilities. In this study, five dominant fungal strains were isolated from an aged lindane polluted site, they all mixed (100 mg each) together with pent mushroom compost (SMC) applied soil (5 kg) at 10, 20, 30, 40% control 0% (soil no treatment), these used grow M. maximus Jacq for 3 months. To establish degradation, deductions such as Degradation rate...

Soil pollution is an unavoidable evil; many crude-oil exploring communities have been identified to be the most ecologically impacted regions around world due hydrocarbon and their concurrent health risks. Several clean-up technologies reported on removal of hydrocarbons in polluted soils but them are either very expensive, require integration advanced mechanization and/or cannot implemented small scale. However, "Bioremediation" has as efficient, cost-effective environment-friendly...

Abstract Plants are exposed to different environmental stresses (biotic or abiotic) in their habitats, these often result several diseases and decline crop production which major concerns producers scientists. Habitat‐imposed biotic stress is one of the most common problems production. The use chemical‐based pesticides has been widely reported control plant but residual effects excessive application necessitates biological agents known play important safety roles disease management....

Trichoderma fungi have been proved as efficient bioagents with great antifungal properties while many species in the plant's rhizospheres characterized plant growth-promoting agents. However, rhizosphere are yet to be fully explored for disease management. In this study, were isolated from of maize, banana, and cassava, their biocontrol potentials screened against some Fusarium oak leaves (F2B F3) laboratory cultures (Fus 296 Fus 294). The identified virens 1 (TCIV), T. 2 (TCVII), 3 (TMSI),...

Abstract Bioethanol production from monomeric sugar is performed by several yeasts. But there are limitations associated with yeast strains such as their low tolerance to ethanol, toxic inhibitors, and high concentration. Genetic metabolic engineering of potential can overcome the above limitations. The present article summarized current genetic approaches for development strain efficient ethanol production. review systematically examined bioethanol generations based on substrate...

This work aimed to analyze the nutrient values, examine biodeteriorating fungi biota, and mycotoxin contents of "Suya spices." Fungi with highest percentage occurrence on all samples are Aspergillus niger, flavus, parasiticus, ochraceus, Fusarium sp., Rhizopus stolonifer, yeast, Trichoderma koningii. Nutrient composition is significantly different statistically (P < 0.05) high protein (9.53% 13.17%), fiber (9.27 carbohydrate (46.27% 50.90%), ash (8.47% 9.70%) but low moisture (9.03% 9.47%)...

Laccase is a multicopper oxidase enzyme that oxidizes variety of substrates, including polyphenols and polycyclic aromatic hydrocarbons (PAHs). It catalyzes the four-electron reduction molecular oxygen results in production water as by-product. Thus, laccase can play an important role environmental care. Previously, we have successfully expressed

Fungal laccase (Lac) has become a very useful biocatalyst in different industries, bio-refineries and, most importantly, bioremediation. Many reports have also linked hydrocarbon tolerance and degradation by various microorganisms with Lac secretion. In this study, Trametes trogii (Ttlcc1) was engineered into Saccharomyces cerevisiae strain CEN.PK2-1 C under the constitutive GPD promoter (pGPD) for multi-fold synthesis efficient degradation. Protein expression heterologous hosts is strictly...

Abstract Background: Stimulatory efficacy of spent mushroom compost (SMC) cannot be overemphasized. Aims: In this study, the effect SMC on phytoremediation and plant's response to heavy metal polluted soil was investigated suggested for establishment feasible remediation. Methods: Heavy (80 kg) sterilized at 121°C in sterilizer 30 min repeated four more times remove microbial interference. Five kg packed into pots supplemented with Pleurotus ostreatus different concentrations 10, 20, 30,...

Background Global food systems in recent years have been impacted by some harsh environmental challenges and excessive anthropogenic activities. The increasing levels of both biotic abiotic stressors led to a decline production, safety, quality. This has also contributed low crop production rate difficulty meeting the requirements ever-growing population. Several stresses developed above natural resistance crops coupled with alarming contamination rates. In particular, multiple antibiotic...

Feedforward loops (FFLs) are relatively simple network motifs, made of three interacting genes, that have been found in a large number E. coli and S. cerevisiae. More recently, they also discovered multicellular eukaryotes. FFLs evolutionary favored motifs because enable cells to survive critical environmental conditions. Among the eight types possible FFLs, so-called coherent 1 incoherent FFL most abundant. The former carries out sign-sensitive delay gene expression; latter is pulse...

The antimicrobial potential of Trichaptum biforme and Bjerkandera adusta extracts were evaluated on some selected bacteria Candida albicans. Our results showed that aqueous, methanol ethanol T. B. exhibited no activity against However, very effective three Gram-negative ( Escherichia coli, Salmonella typhimurium Pseudomonas aeruginosa ) Gram-positive Staphylococcus aureus, epidermidis Bacillus cereus ). Likewise, also all only one coli . effectiveness these two fungi as antibacterial agents...
