| Summary: | Abstract<br /> The study was conducted in Mosul city, northern Iraq to obtain a local isolate of the algal, Fragellaria vaucheria (Bacillariophycophyta) . Maximum biomass (58 mg/l) was obtained after seven days of incubation. The ratio of precipitated biosilica in the cellular walls ranged between 30 to 35 % of the dry weight of the biomass. The amount of biosilica increased with progress of incubation period. The infra red spectrum test showed the high purity of isolated silica.<br /> The protein content increased with increase of algal growth and reached 125 mg/l after fifteenth days of incubation, Maximum lipid content (198 mg/l) was obtained after eleven days of incubation. Generally final pH value was higher than the initial one. The algal Fragellaria vaucheria have a wide pH range and the optimum pH for growth was 7.6 . |
