Their presence and numbers were influenced by the availability of breeding sites. This study reports the occurrence and colour preferences of oviposition in man-made habitats under field conditions by female mosquitoes found in the Water Board Station at Runjin Sambo Area, Sokoto. A total of nine plastic buckets (2 litres) of different colours were used as artificial oviposition container. The colour chosen was black, blue, brown, pink, purple, red, white, and yellow. The containers were filled with an equal amount of water and placed under a shade at 5 cm interval and observed daily for seven days. Mosquito larvae were emptied into a bowl and counted. The result showed that <em>Aedes </em>and <em>Culex</em> larvae were oviposited in all the plastic container with high abundance in a red colour plastic container (25.10 and 26.30% respectively) while <em>Anopheles </em>larvae were more in the black container (25.5%) and <em>Mansoni</em> on brown (23.10%). This suggested that container colour was important in influencing the oviposition choices of some female mosquitoes breeding in artificial containers in the Water Board Station at Runjin Sambo Area Sokoto. It is hoped that the study will help in adopting control measures for the respective mosquito species.</p> H. M. Bandiya M. A. Yahaya H. A. Shindi A. Bello A. S.

They are quite specific concerning with regard to their substrates. Enzymes lower the activation energy and increase the rate of biochemical reactions. According to the type of reaction catalyzed, enzymes are currently subdivided into six classes, namely oxidoreductases, hydrolases, transferases, lyases, isomerases, and ligases.</p> <p>The effects of toxic chemicals and chlorophenolic compounds on enzyme activity are determined by fast, useful, and simple enzymatic methods. These methods can be carried out in low volumes and automatically using equipment such as a spectrophotometer, fluorometer and scintillation counters.</p> <p>In this study, a new microtoxicity test was developed with the use of the fungal and bacterial β-galactosidase enzyme. In the toxicity experiments, the effects of 2,4,6-trichlorophenol (2,4,6 TCP), 2,4-dichlorophenol (2,4 DCP) and 4-chlorophenol (4 CP) over the β-galactosidase enzyme activity were investigated.</p> <p>In this study, the bacterial and fungal β-galactosidase enzyme was found to be effective in determining the detoxification of some chlorinated phenolic compounds, 2,4,6-TCP, 2,4-DCP, and 4-CP, through the treatment with laccase enzyme. The inhibitor effect of toxic compounds on the activity of the β-galactosidase enzyme was examined. As a result of the studies, 61% inhibition for 2,4,6-TCP, 58% inhibition for 2,4-DCP and 47% inhibition for 4-CP was observed.</p> <p>Mikrotoxicity test system developed in our laboratory which works principally based on inactivation of β-galactosidase activity by toxic chlorinated phenolics, was used for toxicity detection. Data obtained from microtoxicity tests have shown that the dechlorination of chlorinated phenolics with laccase has resulted in the loss of toxic potentiality of these chemicals to a substantial extent.</p> <p>We thought that this study is to be an important contribution to bioremediation science and environmental technology with a new biotechnological approach.</p> Arzu Ünal ##submission.copyrightStatement## 2020-06-01 2020-06-01 14 18 10.9734/ajob/2020/v9i230083 Anti Inflammatory and Anti Viral Effects of Potassium (K) and Chemical Composition of Moringa <p>Moringa grows in parts of Africa and Asia and is a flowering plant from herb to tree. There are 13 types of Moringa. It is growing in the Himalayas in northwestern India. In Africa, it grows in Kenya, Somalia, Ethiopia, Madagascar, Ghana, Nigeria and more. For capsules, leaves and roots are used. Oil is used for nuts.</p> <p>Moringa in the research was from Thailand. The colors of flowers were white and yellow.</p> <p>Moringa is characterized by high levels of potassium (K). Patients with COVID-19 caused by the SARS-CoV-2 virus have a decrease in potassium levels in the body.</p> <p>In 2017, the author makes a spectral analysis of Moringa oil (Ignatov, 2017). The analysis justifies the application of Moringa for coronaviruses.</p> <p>The great advantage of Moringa is that potassium and the chemical compounds are in organic form and are well absorbed by the body.</p> Ignat Ignatov ##submission.copyrightStatement## 2020-05-28 2020-05-28 1 7 10.9734/ajob/2020/v9i230081
