Comparison between the level of contamination of the analyzed tannery effluent and the standard given by national and international environmental regulatory bodies was carried out. A total of 40 samples were collected; 20 each from treated and untreated samples. The samples were analyzed by multiple tube fermentation technique using Most Probable Number (MPN) method. All the untreated tannery effluent samples show the presence of coliform bacteria 40 (100%), while, 6 (30%) of the treated tannery effluent samples show the presence of coliform bacteria. There is significant difference (p<0.05) between microbial load in the treated tannery effluent and untreated effluents analyzed. Most of the t...

Fungi are the main amylase-producing microorganisms. Aims: The present study targeted to screen Penicillium species isolated locally from soil for amylase production. Materials and Methods: In this research, fungal species belonging to genera penicillum species were isolated from soil and screened for their ability to degrade cellulose (lactose, fructose, sucrose and dextrose) for enzyme activity. Enzymatic fungi were evaluated after 7 days for the production of amylase enzymes by lactophenol microscopic examination. The concentrations for 7 days of production were formulated by dilution method as 0.148 mg/ml, 0.313 mg/ml, 0.303 mg/ml, 0.127 mg/ml, 0.161 mg/ml, 0.079 mg/ml and 0.099 mg/ml respectively. Results: The maximum amylase production was obtained on the 2nd day of production whi...

Materials and Methods: Ten samples of different brands were aseptically collected and analyzed using heterotrophic count and most probable number technique. The isolated bacteria were microscopically and biochemically characterized and finally confirmed using Box™ Easygel® E. coli Quantitube™ Test Kit (Micrology Laboratories manufactures, Easygel®, USA) biotyping. Physicochemical analysis of the samples was done using standard methods. The isolated bacteria were screened for antimicrobial susceptibility using Kirby-Bauer disc diffusion technique. Results: The total heterotrophic bacterial count ranged from 1.0×102 to 3.0×102 cfu/ml, with MPN/100ml values ranged from <0.03 to 1.2. The temperature ranged from 8 to 18°C, at the pH range of 5.0...

The mycoflora were isolated using dilution plate technique on Potato dextrose agar amended by 1% streptomycin. Identification was made microscopically using the lacto-phenol cotton blue method and macroscopically by comparing the cultural and morphological features with the help of authentic fungal manual and taxonomic key. The identified species are; Aspergillus niger, A. flavus, A. fumigatus, A. nidulans, A. oryzae, Alternaria longifes, Fusarium oxysporum, F. solani, F. mangifera, Rhizopus stolonifer, R. orizae, Saccharomyces cerevisae, Trichoderma harzianum and Trichophytum quallinum.

Treponema pallidum, the causative agent of syphilis has been a public health challenge for centuries. Sexually transmitted infections (STIs) among pregnant women are wide spread in the developing countries, and constitute a major public health problem in sub-Saharan Africa. Information regarding the prevalence of syphilis in pregnant women is scanty from the north-west zone of Nigeria. Aims: Evaluation of seroprevalence of Treponema pallidum infection among pregnant women attending a selected hospital at Northern Nigeria was carried out, with view to assess the socio-demographic data and predisposing factors of syphilis among the study population. Methods: Exactly 200 pregnant women, who attended antenatal clinic of the selected hospital at Northern Nigeria, from July to September, 2015 were screened for syphilis using syphilis rapid immunochromatographic test for in-vitro...

Dyes are hazardous, mutagenic and carcinogenic organic pollutants discharged into the environment... more Dyes are hazardous, mutagenic and carcinogenic organic pollutants discharged into the environment from textile effluents, tanneries and other industries. Rice husk was believed to serve as good sorbent for many metals and basic dyes including Congo red dye. The present study targeted to remove Congo red dye from a prepared wastewater using rice husk as adsorbent, with view to use thermodynamic parameters such as entropy, enthalpy and free energy models to explain the mechanism for the dye adsorption using rice husk powder as adsorbent. In this research, rice husk was collected from Panshekara area, Kano state, Nigeria. The sample was processed using standard techniques. The sample was treated with sulphuric acid and used for the uptake of the dye by adsorption process. The filtered samples were developed using UV spectrometry. Thermodynamic studies were carried out using standard procedures. Congo red dye can be removed from aqueous medium by the process of adsorption using rice husk adsorbent. The thermodynamic studies of the adsorption process that were conducted using various temperatures (30, 35, 40 and 45°C) revealed that the reaction is endothermic, and there was increase in the randomness of the solid/solution interface during the adsorption of Congo red onto the rice husk. The thermodynamic parameters analyzed such as enthalpy (ΔH), entropy (ΔS), free energy (ΔG) and isosteric heat of adsorption (ΔHr), suggest that the overall adsorption process was physisorption. The enthalpy-entropy compensation theory can be applied to the sorption phenomena of rice, since sorption and desorption processes can be controlled by enthalpy.
