Application of statistical response surface methodology for optimization of fluoride removal efficiency by Padina sp. alga.

Human exposure to fluoride in drink water at a level above 1.5 mg/L causes a lot of health problems. The present study was carried out to assess the fluoride biosorption capability of Padina sp.

Evaluation of antagonistic actinomycetes isolates as biocontrol agents against wastewater-associated bacteria.

In wastewater treatment plants the antagonistic activities of actinomycetes could be contributing significantly in microbe-removing mechanisms, which are a combination of different factors. For this purpose, out of 58 actinomycetes isolates from a wastewater treatment plant in Al-Fayoum Governorate, Egypt, only 36 different morphological isolates were selected for further studies. Although 35 isolates (97.
