The investigations of this study were divided into three parts:
• 108 species belonging to 40 genera were isolated in the present investigation from 36 samples of each
aerobic and anoxic activated sludge collected from 2 wastewater treatment plants in Berlin during 10
months. Five isolation media were used at 30 oC for 1-2 weeks.
• Twenty-one isolates were screened for the elimination of compounds from raw wastewater in shaker flasks
at 30 oC for 15 days. Two isolates were the best for growth parameters and elimination of TN, PO4, NH4,
NO3, and COD from raw wastewater. These were Aspergillus niger and Trichoderma viride. The elimination
values of nitrogen were (86.3 % and 88.5 %) and phosphorous (95.0 % and 96.3 %) for Aspergillus niger and
Trichoderma viride, respectively. While the ability of other isolates for elimination of nitrogen and
phosphorous was low. Thus in the following section these isolates were selected to examine their activity
under different conditions. The best environmental conditions for dry matter, protein content and elimination
of compounds from raw wastewater by Aspergillus niger in shacked flasks were as follows: optimum pH 4.5
- 6.0; 30 oC and incubation periods, 6 days for dry matter, 7 days for protein content, 3 days for elimination
of PO4, 4-5 days for NH3, 4 for TN, NO4 and 4 days for COD. Whilst the optimum conditions for growth and
elimination of compounds by Trichoderma viride were pH 4.5; 25 - 30 oC and 4 -7 days.
• Fungal growth and elimination of compounds from raw wastewater was showed in 2L batch reactor under
aerobic and anaerobic conditions. The highest elimination rate of compounds from raw wastewater by
Aspergillus niger and Trichoderma viride under aerobic condition was reached after 3-4 and 2-5 days,
respectively. The mycelium dry matter and protein content of Aspergillus niger after 15 days were 5055mg/L
and 259.0 mg/L, respectively. However the highest values of dry matter and protein content of Trichoderma
viride after 15 days were 7030.0 mg/L and 295.75 mg/L, respectively. Under anaerobic conditions the
highest elimination rate of compounds by Aspergillus niger and Trichoderma viride were attained after 5-8
and 3-5 days, respectively. The mycelium dry matter and protein content of Aspergillus niger and
Trichoderma viride were (3040.0 mg/L and 217.5 mg/L) and (4080.0 mg/L and 263.8 mg/L), respectively.
Most fungi recovered in the present investigation can be considered as potential pathogens and some of these
fungi also produce mycotoxins. Therefore, all workers in the field of activated sludge process, wastewater
treatment and farm operation should be careful to avoid mycotic infections and the productions must be
adapted to control the spread of pathogenic fungi in the environment. Also these experiments illustrate the
possible health risk problems that may arise in the use of sludge for land reclamation and fertilization. Fungi
were proved to have potential for wastewater treatment under special laboratory conditions such as low pH,
temperature and aeration. Also fungal biomass produced could be used as a source of food for animal or
human consumption (as enzymes), due to its high protein content.

Serial dilution method was utilized in the isolation and enumeration of the fungal isolates of the 20 contaminated soil samples on. The obtained data show that 34 species belonging to 14 genera were identified from soil contaminated with used petroleum products in mechanic workshops samples. Aspergillus had the highest percentage prevalence (86 %). followed by Penicillium (37 %), Cladosporium (23 %) and Fusarium (13 %) species were the most prevalent. twenty-one (70 %) out of the thirty isolates were able to utilize the crude oil at varying rates. Six isolates (Aspergilus niger, 80 %, Penicillium funicuolosum 75.0, Cochliobolus lunatus 68.5, Penicillium chrysogenum 67.5, Trichoderma harzianum, 65.0 and T. viride 62.5 %) utilized the oil at considerably high rate. In conclusion, the results indicate that soil within the premises of automobile workshops is a good habitat for different groups of fungi. The ability of fungi to treat oil pollutions and grown on them. Suggest that it can be employed as bioremediation agent and can be used in restoring the ecosystem when contaminated by petroleum and its derivatives.

The prevalence and intensity of gastro-intestinal nematode infection in their relation to season ... more The prevalence and intensity of gastro-intestinal nematode infection in their relation to season and rainfall were investigated from 429 female dromedary camels at Tambul market in the Butana plains (Sudan), during 1985-1986. The investigation revealed a similar seasonal pattern in the prevalence as well as the intensity of egg output. The seasonality is mainly brought about by Haemonchus spp. and Impalaia spp. while Trichostrongylus spp. seem to be present as adults throughout the year. There is a good correlation between high egg counts and rainfall ensuring optimal development of preparasitic stages.
