This study systematically investigated the effects of a low-intensity magnetic field on the influence of keratinase activity, peptide yield, and structural and functional properties of peptides produced during solid-state fermentation (SSF) of mixed organic substrates (chicken feather powder and okara) using a mutant strain of Bacillus licheniformis. Initially, the magnetic field-assisted SSF (MSSF) conditions were optimized, which provided the optimized conditions as the number of treatments 3 at every 24 h (24, 48, and 72 h) with 4 h holding time at 120 Gs of magnetic intensity (mI). Under the optimum conditions, keratinase activity and peptide production increased by 10.31% and 13.77%, respectively. Further, in order to evaluate the influence of magnetic field treatment on the peptides, MSSF experiments were done under different mI conditions (40, 80, 120, and 160 Gs), followed by the evaluation of the structural changes of the extracted peptides. The structural analysis revealed that mI had a significant impact on the keratin surface. In contrast, secondary structure analysis confirmed the unfolding of the peptide with decreased α-keratin and increased β-keratin, thereby boosting the bioactive properties of the peptides. The highest hydroxyl free radical (.OH), 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging and Fe2+ chelating rates (56.55, 71.36, and 50.72%, respectively) were found at 120 Gs, which were insignificant with the results at 160 Gs. Therefore, MSSF has a positive effect on the proteolysis mechanism, which can increase bioactive peptide production from keratin.

Underground water （Borehole） has been the main alternative source of drinking water for most communities in my country. Previous studies have revealed high levels of contamination. The origin of which can be attributed to geochemical processes, combustion of fossil fuels, mining and anthropogenic activities. Most borehole water and well water in local communities of Nigeria are not safe for drinking due to heavy industrial and environmental pollution. This study was undertaken to assess the quality in some selected boreholes in the Port Harcourt metropolis for a period of two years. Borehole water samples were randomly collected from thirteen boreholes in a local community in plastic bottles （100 mL） in the months of September for the years of study （2010 ＆ 2011）. Four out of the seven heavy metals analyzed were found to be present in the first year of study. These were Fe, Cu, Mn and Zn. In the second year of study, Pb, Cr, Fe and Co were not detected in all of the samples except Cu and Fe which were present in only two samples. Mn and Zn were found to be present in all of the samples for both years of study.

Sludge contains organic and inorganic compounds including traces of heavy metals such as lead (Pb), cadmium (Cd), copper (Cu), nickel (Ni), chromium (Cr) and others. These metals restrict the use of sludge in agriculture because their accumulation is harmful to the environment and particularly the food chain. Cadmium and lead are among the most common heavy metals found in municipal wastewater treatment plant sludge. They are capable of bioaccumulation in plant tissues like roots and leaves and are non-biodegradable and therefore they remain in the sludge which is disposed on land or used as fertilizers on farms. The presence of heavy metal pollutants serves as a great threat to soils and also makes plants grown on such soils unfit for animal and human consumption as they may have detrimental effects to animal and human life. For instance, Pb and Cd are known to be human carcinogens. This study therefore aimed to investigate the levels of Cd and Pb in the treated dry sludge from Lubigi Feacal Sludge and Wastewater treatment plant located in Kawempe division, Kampala city, Uganda so as to ascertain its safety for use on agricultural lands. Two batches of samples were collected and analyzed at Government Analytical laboratory in Wandegeya, Uganda. The acid digested sludge samples were analyzed using Atomic Absorption Spectroscopy (AAS) method. The average concentrations of Pb found in collected sludge samples, batch 1 (11.912 mg/kg dm) and batch 2 (5.304 mg/kg dm) were far below the Environment Protection Agency (EPA) maximum permissible concentration (840 mg/kg) for any land application. Cadmium was not detected in all the sludge samples collected;there is an implication that it is either completely absent in the sludge generated by the plant or present but far below detectable levels. The sludge generated from Lubigi fecal sludge and wastewater treatment plant is therefore safe for application on agricultural lands as far as Pb and Cd concentrations are concerned.
