  Juice was produced from watermelon and stored at room (28±2°C) and refrigeration (8°C) temperatures and was analyzed for its microbiological and nutritional qualities. The total aerobic bacterial, coliform, mold and yeast counts increased with time. Total aerobic bacterial counts ranged from 1.5×102 to 3.6×103 for water melon juice (WM), 1.3×103 to 2.3×102 for water melon/orange juice mix (WO) and 1.0×103 to 2.9×102 for commercially packaged juice (ST). Coliform counts were 1.0×103 to 2.9×102 for WM, 2.1×102 to 2.3×103 for WO and no counts were recorded for ST, while the yeast counts ranged from 2.4×102 to 2.6×103 for WM, 2.4×103 to 3.2×103 for WO and 0 to 1.2×102 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.

  The increase in demand for crude oil as a source of energy and as a primary raw material for industries has resulted in an increase in its production, transportation and refining, which in turn has resulted in gross pollution of the environment. In this study, Saccharomyces cerevisiae isolated from a commercially prepared local fermented beverage ‘zobo’ (prepared from Hibiscus flower) was tested to determine its potential to degrade crude oil for a period of 28 days under aerobic condition. The percentage of oil biodegradation was determined using weight loss method and gas chromatography mass spectroscopy (GC/MS) of the residual crude oil after 28 days. At the end of 28 days 49.29% crude oil degradation was recorded. The result suggests the potential of Saccharomyces cerevisiae for bioremediation of oil polluted sites.

  This study was to assess the Phytoextraction of Acalypha inferno for Zinc (Zn) contaminated soil. Stems were planted in five kilograms (5 kg) of the soil placed in each plastic pot having 0 ppm (control), 5, 10, 15, 20 and 25 ppm of Zn. The experiment was on for a period of 12 weeks. The results revealed that pH, phosphorous and moisture contents increased while nitrogen and organic carbon contents decreased in polluted soil remediated with Acalypha inferno. The plant compartments were analyzed for Zn uptake. Appreciable concentrations of Zn in different compartment of the plant was recorded, 7.12, 7.10 and 9.06 ppm for stem, root and leave, respectively. Bioconcentration Factor (BCF) and Translocation Factor (TF) was assessed. It was observed that more concentration of Zn was translocated from the roots to the leaves. The results obtained suggest that Acalypha inferno have phytoextraction ability and could be used in restoring soil polluted with zinc (Zn).

  A study was designed to assess the efficacy of yeast isolated from spoilt water melon in the biological treatment of pharmaceutical effluent. Two yeast species were identified as Saccharomyces cerevisiae and Torulaspora delbrueckii. Each of the yeast was inoculated into the effluent and incubated for 15 days. Saccharomyces cerevisiae shows the highest percentage reduction of 52.5, 52.5 and 58.7% for BOD, COD and nitrate respectively of the pharmaceutical effluent and closely followed by the consortium which has 44.5, 44.5 and 72.0% for BOD, COD and nitrate reduction, respectively. The least percentage reduction was displayed by Torulaspora delbrueckii with 38.3, 38.3 and 79.7%. The study revealed that Saccharomyces cerevisiae isolated from spoilt water melon could be used in the biological treatment of pharmaceutical effluent.
