  To investigate genetic variability in Moringa oleifera Lam., 75 accessions from the Sudan and Guinea savanna zones in Nigeria were taxonomically analysed using Random Amplified polymorphic DNA (RAPD) markers. The electrophoresis bands were analysed using NTSYSpc software and the result of their matrices indicated different variability in the accessions. High degrees of polymorphism (74%) among the accessions were observed in terms of genetic relationship and were grouped into five clusters. This high variability can be utilised for mapping out breeding strategies in the production of cultivars with better yield of M. oleifera to meet the pressing needs of these multi-purpose crop to our growing populations.

  Excessive use of pesticides are disturbing major components of ecosystems. Therefore their removal using biodegradation technique is the need of time. In present study, 35 microbial strains were isolated from industrial drain which carries effluents from chlorpyrifos manufacturing plant. These strains significantly differ in their ability against chlorpyrifos resistance and degradation. Out of these strains WW5 was found most resistant and effective in chlorpyrifos degradation. On the basis of morphological, biochemical and physiological characteristics, strain WW5 was identified as Pseudomonas sp. Biodegradation potential of WW5 strain was studied under different culture conditions like concentration of chlorpyrifos, carbon sources, pH and inoculum densities. In the presence of glucose chlorpyrifos was co-metabolized. High pH (8) and high inoculum density (108 CFU/mL) show most efficient results in biodegradation. Presence of other nutrients enhanced chlorpyrifos degradation probably due to high growth on easily metabolizable compounds which in turn favors biodegradation. The strain WW5 showed 94% degradation of chlorpyrifos (400 mg/L) within 18 days of incubation. This strain can be used for bioremediation and ecological restoration of sites, contaminated with chlorpyrifos.
