In this paper, identification, cultivation, uses, side effects, nutritional and medicinal values, storage, marketing and other uses of mushrooms were discussed. From the review too it was observed that its usefulness surpasses the side effects. These side effects could be eliminated if proper 'processing' could be employed. Due to advances in both basic knowledge and practical technology relevant to mushroom farming, mushroom products and mushroom bioremediation, developing countries should harness the potentials of mushrooms as this would boost the revenue income and healthy living.

The present study evaluated the effects of fermentation on nutrients and anti-nutrients composition of jujube (Ziziphus mauritiana Lam) seed. Methods: The seed of Z. mauritiana was fermented for 24 hr. Standard analytical procedures were used to analyse the proximate, minerals, amino acid, fatty acid and anti-nutrient compositions of the seed sample at 0, 6, 12, 18 and 24 hr of fermentation. Results: The seed has high amounts of proteins, minerals, amino acids and low levels of anti-nutrients. The seed also has higher unsaturated than saturated fatty acids. Fermentation significantly increased the minerals compositions, decreases anti-nutrients and some amino acid levels but had no plausible effects (p>0.05) on proximate contents of the seed. Fermentation for 6 and 12 hr ha...

Using the agar diffusion techniques, the crude aqueous extract showed activity on strain SP91 at 4.0mg/ml. The minimum inhibitory concentration (MIC) was 0.7 mg/ml. The minimum bactericidal concentration (MBC) was 2.0 mg/ml. The results of the phytochemical screening revealed the presence of alkaloids, carbohydrates, tannins, saponin etc. The results of this study suggest that Eucalyptus globulus could be a potential source of chemotherapeutic drugs that can be used for the treatment of pneumonia.

The effects of pH, contact time, concentration of metal solution and adsorbent dosages were monitored using Multi-metal batch adsorption technique at 32 0 C. The residual concentrations of the potentially toxic elements were determined using atomic absorption spectrophotometer. The results of the uptake level of the metal ions were found to be dependent on pH of the solution, metal ions type and adsorbent dosage. The adsorption mechanism indicated that biosorption of Co 2+ and Cd 2+ ion fitted better for Freundlich isotherm while the biosorption of Cu 2+ ion was observed to fit well to the Langmuir isotherm. The maximum sorption uptake of the studied metal ions by Blighia sapida seeds was in the order of Cu 2+ > Cd 2+ > Co 2+ ions. This study justifies that Blighia sapida seeds might serve as a viable low cost agricultural waste to remove poten...

Water was used as dye extracting solvent. Dye-sensitized solar cells (DSSCs) from dye extract of pH 3.0 had the highest photocurrent density Jsc of 18.61 mA/cm and highest fill factor FF of 0.60. While the Dye-Sensitized solar cells (DSSCs) from dye sensitizer pHs of 1.23 and 5.7 had photocurrent densities Jsc of 5.79 mA/cm and 11.34mA/cm, and fill factors of 0.42 and 0.57 respectively. The maximum powers Pmax of the DSSCs were 1.07, 4.91 and 2.85 for dye sensitizer pH of 1.23, 3.0 and 5.7 respectively. Keywords—Dye sensitizes solar cell; Dye sensitizer; Bougainvillea glabra; pH

Twenty-five weaner rats were allocated into five groups of formulated diet consisting of treatment 1 - 5 in which soya bean was replaced with Ziziphus mauritiana seed at 0% (control), 25%, 50%, 75%, and 100% respectively for 3 weeks. Effects of the diets on lipid profile, haematology and serum chemistry were evaluated. Rats fed 25%, 50% and 100% Z. mauritiana had significantly higher feed intake and weight gain when compared with the normal control. All levels of inclusion tested increases the concentrations of serum total proteins and bilirubin but decreases the cholesterol and platelet counts when compared with the control. No diet related alterations were recorded for the relative organ’s ratio, a...

Standard methods were employed for the task and the results were subjected to statistical analysis. The results obtained compared favourably with other studies. From the results, it was observed that NaCl had the best protein solubility from 9.05 ± 2.00 to 56.31 ± 2.70 % and significantly differed from one another at p> 0.05. It is recommended that in food formulations, different concentrations of NaCl should be harnessed.

Until now, there are only a few studies on nitrosamine, particularly N-nitrosodimethylamine in swimming pool water. This could be due to the lack of a suitable method that is sensitive enough for the measurement of N-nitrosodimethylamine in pool waters. Other disinfectant byproducts formed in pool water widely documented are trihalomethanes, haloacetic acids, halonitromethanes, and chloramines but inadequate information on N-nitrosodimethylamine. This paper provides a review of the nitrogenous disinfectant byproduct in swimming pools and its health implications. Anthropogenic substances introduced by swimmers such as sweat, lotions, and urine contribute to the formation of N-nitrosodimethylamine. The reaction of secondary amines such as dimethylamine with mono/dichloroamines produced dimethyl hydrazine and further undergo oxidation to form N-nitrosodimethylamine. The reaction of chlorine and o...
