This study aimed to: (i) monitoring of a collection of organochlorine pesticides (OCPs) in three agricultural drainages (Nashart, no. 9, and El-shoka), located in Kafr El-Sheikh governorate, Egypt; and ii) investigate the biodegradation potential of different bacterial isolates regarding organochlorine pesticides.Material and methods: Analysis of OCPs was carried out by gas chromatography, Enrichment cultures were used for isolation of the bacterial strains capable of OCPs biodegradation and the most efficient isolate was identified based on morphological, biochemical ad molecular characteristics.Main results: The determination of OCPs in water samples by gas chromatography showed varying values of OCPs ranging from 0.0 mg/L (below detection limit) to 0.0385 mg/L. A total of four morphologically different bacterial isolates were obtained, which showed a remarkable ca...

These nanoparticles may contaminate the environment under certain conditions. The transport, mobility and sorption and bioavailability of nanoparticles is controlled by factors such as soil texture, clay content, pH, cation exchange capacity and soil organic matter. Here we review the fate of nanoparticles in agrosystems. Phytotoxicity of nanoparticles and nanofertilizers are highlighted.

The current research focused to produce the bioethanol from crop wastes. The study carried out in Agricultural Engineering Department and Agric. Botany Department at faculty of Agriculture, Kafrelsheikh University. The main objective in this part of the current study is producing the bioethanol from potato wastes to applicable in the engine of the farm machine. The experiment was carried out in aerobic batch digester and bioreactor after potato tubers wastes pretreatment with Bacillus subtilis (E34) as amylolytic bacteria for 7 days. The bioreactor system consists of three main units. The first unit was ethanol reactor which represents the main unit of the fermentation process and the second is the agitating unit required to enhance the fermentation process and to increase the efficiency of ethanol production for all treatments. Third unit is the collector tank; it ...
