Mucor hiemalis, Trichoderma viride biomasses and their consortium were assayed as biosorbents of heavy metals in liquids. The influence of initial metal concentration, biomass concentration, pH and contact time on their biosorption capacity to Fe, Pb and Cd were investigated in separate and consortium cultures. The increase in biosorption rate occu...

Architectural stucco carvings suffer from many aspects of deterioration due to environmental corrosion factors, especially moisture. Moisture is the key factor for the establishment and spread of fungi within the stucco granules, and it leads to the surface decomposition and fall of the stucco surface parts near the end of the incubation period. An...

Diversity of mycobiota in the sediment of Lake Manzala was investigated to evaluate their efficiency in heavy metals biosorption. Results showed that all sediment samples collected from different sites of Lake Manzala were contaminated with Cd, Fe, Cu, Mn, Pb and Zn but in various concentrations. Aspergillus, Penicillium, Mucor and Trichoderma were...

An investigation was conducted to assess the concentration of heavy metals in sediments in five selected locations along Manzala lagoon and correlate the effect of metal concentrations on benthic fungal population. Physiochemical analysis showed that pH values ranged between 7.93 and 8.1 while electric conductivity ranged between 5.64 and 12.76 dSm...

Fungi are known to degrade, or cause to deteriorate, a wide variety of materials and compounds, processes known as mycodegradation and mycodeterioration. Plastic is one of the most common synthetic polymers used in various applications such as coatings, fibers, paints and packaging. However, plastic has many advantages i.e., lightweight, low cost a...

A total of 22 fungal species belonging to 13 genera were isolated from rice straw. Mitosporic fungi were representby 7 identified genera, in addition to 2 sterile mycelia. Zygomycota comprises 3 genera and Ascomycota represented only by a single. These fungi were screened for their abilities to produce xylanase, cellulase and peroxidase enzymes on...

Twenty samples of polluted water were collected from Damietta's canals and drainages located near the industrial area of New Damietta. Initial concentrations of heavy metals including (zinc, copper and lead) in the polluted water were determined. Fourty–five fungal species were isolated. Mucor racemosus, Aspergillus flavus, A. niger, A. fumigatus,...

Oil-polluted areas contain large amounts of poly-aromatic hydrocarbons (PAHs) which represent severe hazards on the ambient environment.
