“…(57.1 to 89.2%) and Alternaria spp. (82.4 to 100%) species were the predominant fungal species as endogenous mycoflora (Kachuei et al, 2009). While mycological survey carried out by Embabyet al (2012) on freshly harvested wheat grains from the main production regions in Egypt resulted in eight fungal genera isolates and some identified as: Alternaria (36.9%) and Penicillium (18.3%) were in agreement with the results of this study.…”

Cereal and its products are susceptible to mold damage during pre-and post-harvesting stages of the production. This study was carried out to determine the extent of fungal contamination and the aflatoxins AFB 1 , AFB 2 , AFG 1 , AFG 2 levels of fifty wheat grain samples were collected randomly from different markets in the five Gaza governorates. The obtained results indicated that the most common molds isolated from different wheat grain samples were Aspergillus flavus 84%, Aspergillus parasiticus 72%, Fusarium oxysporum 64%, Aspergillus niger 48%, Alternaria alternate 36%, Penicillium 22%, Aspergillus ochraceus 20% and Aspergillus versicolor 4%. Forty one wheat grain samples which represented (82%) were contaminated with aflatoxins. Considering the high incidence of contamination by AFB 1 (80%) in Gaza city and 70% in both Khan Younis and Mid Zone governorates. The level of total aflatoxin AFs in North Gaza, Rafah, Khan Younis, Mid Zone, Gaza City were 8.62, 6.361, 4.187, 3.134 and 2.33 (ng/g), respectively. These levels of AFs are higher than the standard levels in North Gaza, Rafah and Khan Younis. The highest amount of aflatoxin B 1 were found in Mid Zone and North Gaza and their aflatoxins contamination were 2.51 and 2.31 ng/g, respectively.

The objective of this paper was to study the potential for bioremoval of a textile dye, Reactive Red 198 (RR198), by a fungus isolated from soil collected from an effluent disposal area near a textile company. The fungus was identified as Aspergillus flavus, and its use as a low-cost live-cell biomass for the biodegradation of RR198 from contaminated water was investigated using batch studies. The effects of time, dye concentration, and pH as variable factors were examined in the process. Results showed that bioremoval of RR198 by A. flavus increased to over 84.96% with increasing time until equilibrium was reached after a period of 24 h. A low pH was the most effective, as were lower levels of dye concentration. The decolorization was determined by the decrease in the absorption maximums of this dye by UV-visible spectroscopy. A. flavus was shown to be an efficient fungus for removal of RR198 from wastewater.

“…The following procedures were done to identify the strain of oil-removal fungus: Colony formation on SGA was applied to find the type of fungus as previously reported by Kachuei et al (2009), special staining of Penicillium on the slide was done using lacto phenol blue. Finally, we could detect P. commune in our samples.…”

Among all environmental contaminations, industrial oil is one of the major pollutants of soil, water, and air. There are different chemical, physical, and biological methods to remove all types of oil pollutions. One of the common biological methods is to utilize the microorganisms like yeast, fungi or bacteria. Previous studies concerning the biodegradation of an aromatic compound in industrial waste water by Aspergillus niger have been reported. In this study, we tried to identify an oil-derived microorganism and evaluate its efficacy on selfremoval of industrial oil. Firstly, the strain of isolated fungus from various bulks of used oil was defined via colonial identification and DNA sequencing. Secondly, bioremoval activity of defined fungus (Penicillium commune) was evaluated using gas chromatography-mass spectrometry. The optimum conditions in biological elimination of oil including the incubation time, pH level of culture, and amount of reagents were determined. In the best condition, a removal rate of 95.4 % was obtained.
