The total aerobic bacterial, coliform, mold and yeast counts increased with time. Total aerobic bacterial counts ranged from 1.5×10 2 to 3.6×10 3 for water melon juice (WM), 1.3×10 3 to 2.3×10 2 for water melon/orange juice mix (WO) and 1.0×10 3 to 2.9×10 2 for commercially packaged juice (ST). Coliform counts were 1.0×10 3 to 2.9×10 2 for WM, 2.1×10 2 to 2.3×10 3 for WO and no counts were recorded for ST, while the yeast counts ranged from 2.4×10 2 to 2.6×10 3 for WM, 2.4×10 3 to 3.2×10 3 for WO and 0 to 1.2×10 2 for ST. Bacteria isolated were Bacillus sp. Staphylococcus aureus, Klebsiella sp. and Pseudomonas sp., while the mold isolates were Aspergillus niger, Aspergillus flavus and Mucor sp. The yeast isolate was Saccharomyces cerevisiae. Vitamin C and total solid contents decreased with time while total titratable acidity and ash content increased on storage in freshly made juice samples, commercially packaged juice which served as a control showed negligible changes. The general acceptability tests revealed that the commercially packaged juice (ST) was preferred on account of taste and flavor while water melon juice (WM) was preferred based on colour. The water melon/orange juice mix (WO) was however, not preferred because of colour, flavor and taste.

This environmental threat has led to the development of methods used to remediate an oil polluted site, which include the use of physical, chemical, and biological methods. Biological methods have been developed and improved for cleaning up oil contaminated sites and have become an alternative to chemical and physical methods. The potential of bacterial consortium to degrade crude oil was studied for 28 days at 30 C in mineral salt media containing one gram of crude oil. Three bacterial species (Pseudomonas, Micrococcus and Bacillus) were used and their potential to degrade crude oil was tested separately. The best three degrader, were used to construct a bacterial consortium. The highest percentage (98.4%) of total petroleum hydrocarbon degradation was recorded for a bacterial consortium, as compared to the percentage of degradation recorded for single isolate Micrococcus sp. IM6 (77.6%), Pseudomonas sp. IM2 (73.1%) and Bacillus sp. IM4 (67.7%) species, respectively. The result obtained from the study shows that a bacterial consortium is more effective than its single components and it can be used in reclaiming crude oil polluted soil.

Two yeast species were isolated from soil; they were identified as Candida zeylanoides and Saccharomyces cerevisiae. The yeasts were inoculated into flask containing effluent and incubated for 15 days. Saccharomyces cerevisiae showed the most significant treatment capacity with a 66% reduction in BOD; this was followed closely by Candida zeylanoides with 57.3% reduction in BOD and a consortium of the two species showed the least remediation potential of 36.9%. The use of Saccharomyces cerevisiae and Candida zeylanoides in treatment of textile wastewater will help to limit the adverse environmental and health implications associated with disposal of untreated effluent into water bodies.

Rich. and Clematis burgensis Engl. are used in Southwestern Ethiopia to treat otorrhoea and eczema. Antimicrobial activity and MIC of crude extracts were determined by disk diffusion and broth dilution. Phytochemical screening was performed on the extracts. The methanol and petroleum ether extracts of both plants showed antibacterial and antifungal activity. Sensitivity of reference strains was concentration dependent. Methanol and petroleum ether extracts of C. burgensis leaves exerted greater inhibitory effects than C. longicauda extracts whereas aqueous extracts of both plants were inactive. The MIC study revealed a concentration of 0.78 mg/ml on bacteria and 3.125 mg/ml on fungi for methanol extract and 1.56 mg/ml on both fungi and bacteria for petroleum ether extract. Phytochemical screening results indicated the presence of proteins, fixed oils, carbohydrates, tannins, saponins, flavonoids, and steroids. Preliminary chromatographic investigation showed fluorescing spots with R f values that ranged from 0.05 to 0.96 for phenolic compounds and saponins. As the study is one of the first reports on the two indigenous species of Clematis; isolation, purification and characterization of the different primary and secondary metabolites may further yield alternative options to the microbial chemotherapy.

The results obtained from this study indicate that both macroalgae can be employed to adsorb and detoxify any of the three heavy metals from aqueous solution. However, it was also discovered from the study that Cladophora adsorbed and detoxified more of the cadmium and lead than arsenic as the organism had removal efficiency for cadmium and lead as 88.78% and 94.85% respectively meanwhile for arsenic it was only 23.10%. On the otherhand however, Spirogyra adsorbed more of arsenic than cadmium and lead as the organism had a record of 82.76% of arsenic compared to the 28.97% and 47.43%absorption forcadmium and lead respectively. It is therefore concluded based on the results of the present study that reclamation and reuse of water from public or industrial wastewater, or even from water contaminated as a result of precious ...

But scientific study of the plant has been less carried out for which the study was conducted for validation of prevailing medical practice. The soxhlet extraction of the bulbs of plant were conducted in various solvents (hexane, chloroform, ethyl acetate, methanol and water) differing in polarity. Maximum yield (6.79%) was obtained in aqueous fraction and lowest (0.14%) in ethyl acetate fraction. The phytochemical screening of extracts revealed the presence of volatile oil, glycosides, sterol and triterpenes, polyoses, saponins, reducing compounds, quinones, flavonic glycosides and coumarins. In antimicrobial assay conducted by agar well diffusion method, chloroform fraction was found to be more effective towards bacterial and fungal pathogens tested, followed by ethyl acetate and methanol fraction. The hexane and aqueous fractions were found to be least effective against all the tested pathogens. Among the bacterial pathogens, maximum inhibition zone was depicted against Klebsiella pneumoniae (22 mm) by chloroform extracts while among the fungal pathogens, greatest inhibition activity was observed against Fusarium moniliforme (19 mm). The antimicrobial activity of extracts suggested potential use of the plant in treatment of various diseases.

Seeds of C. occidentalis were found to be rich in crude protein, carbohydrate, and mineral elements. Mineral analysis of C. occidentalis showed the seed as good source of antioxidant micronutrients such as iron, calcium, potassium, sodium and magnessium. The phytochemical screening of the seed showed the presence of carbohydrate, terpene, steroid, sugar and tannins. Alkaloids, saponnins and glycosides were absent. Although the oil has a very low peroxide value and high iodine value, it cannot be recommended for consumption because of the low yield as well as its repulsive odour. The seed, however, can serve as a cheap source of protein, energy, as well as antioxidant micronutrients supplements in both man and animal.

Sets of pot experiment were conducted. Stems of Acalypha wilkesiana were planted in five kilograms of soil placed in each plastic pot having 0 ppm, 5 ppm, 10 ppm, 15 ppm, 20 ppm and 25 ppm of Zn respectively. The study was carried out for a period of 12 weeks under natural conditions. Physicochemical properties of the soil were determined using standard methods. The results revealed that pH, phosphorous and moisture contents increased while nitrogen and organic carbon contents decreased in polluted soil remediated with Acalypha wilkesiana when compared to the zinc free soil. Leaves, stems and roots of the plant were analyzed for Zn uptake after 12 weeks. The plant mopped up substantial concentrations of Zn in the stem (6.21 ppm) and leaves (8.23 ppm) compared to concentrations in the roots (6.08 ppm). The phytoextraction ability of the plants was assessed in terms of its metal bioconcentration factor (BCF) and translocation factor (TF). It was observed that the levels of the Zn in the roots and shoots after 12 weeks showed that more bio-available pool of Zn was translocated from the root to the leaves and stem in that order. The results obtained suggests that the plant have phytoextraction capability and could be used in re-establishing soil polluted with Zn.
