Bioremediation of pollutant waters by Trichoderma harzianum using EDX and laboratory Examination

Abstract

The results of water examinations for Al-Najaf sea by used energy dispersive x-ray and laboratory examination and it compare with river water were pH value was 5.5, Chlorides 950 mg/l, Sulfate 834 mg/l and intractability of water was 811mg/l, for water samples from Al-Najaf sea. While were the results for the river samples of water in Al-Najaf city, it were pH value was 6.7, Chlorides 344 mg/l, Sulfate 290 mg/l and Intractability of water was 390 mg/l. The laboratory results showed the role of Trichoderma harzianum in reducing the clear pollution factors in the pollutant waters after detecting it with an electron microscope. Where the results of the biological treatment by Trichoderma harzianum showed that there clear significant differences between the initial tests for the pollutant waters of AL-Najaf sea and the sea waters that were treated as follows : pH value was 6.4, Chlorides 720 mg/l, Sulfate 400 mg/l and Intractability of water was 460 mg/l, for pollutant waters after treatment by Trichoderma harzianum.

In Vitro Effect of Molasses Concentration, pH, and Time on Chromium Removal by Trichoderma spp. from the Effluents of a Peruvian Tannery

“…The Trichoderma treatments may have influenced the reduction of total chromium due to the fungi's ability to develop in media with recalcitrant compounds, showing biosorbent capabilities [33][34][35]. The fact that Trichoderma grows in a chromium-contaminated environment could be due to several factors, such as its ability to produce extracellular enzymes, its ability to take up intracellular organic matter, and a higher intracellular Cr discharge rate from the cell, which could prevent Cr (VI) from getting into the cells of the fungus, thus avoiding damage by chromium [36].…”
