The Concept of Nonribosomal Peptide Sythetases: Industrial Application in Biosynthesis of Antibiotics

Abstract Nonribosomal peptide synthetases (NRPSs) are multimodular enzymes that are used wholly or partly in the biosynthesis antiobiotics; a natural product that fall into the class of secondary metabolites. NRPSs have diverse functions and have also been used in the synthesis of toxins, siderophores, or pigments, among others. Unlike other proteins, its biosynthesis is independent of ribosomal machinery. Nonribosomal peptides are synthesized on large nonribosomal pe...

Comparative Study Between the Eect of Parkia Biglobosa (JACQ) benth and Conventional Antibiotics Against Multiple Antibiotic Resistant Uropathogenic Bacteria (MARUB)

The purpose of this work is to compare the effect of convectional antibiotics with medicinal plant (Parkia biglobosa (Jacq.)Benth) against multiple antibiotics resistant Uropathogenic bacteria isolates.(MARUB), which was isolated from basically two hospital in Ondo State, Nigeria. The two hospitals are Gani Fawehinmi Diagnostic center, Ondo and Federal Medical Center, Owo between July, 2017 and October, 2017. fifty two (52) Gram negative bacteria isolated from urine of UTIs patient at the Ga...

Estimation of Global Solar Radiation Flux Over Ibadan

Renewable energy resources are those having a cycling time less than 100 years and are renewed by the nature and their supply exceeds the rate of consumption. Renewable energy systems use resources that are constantly replaced in nature and are usually less polluting. This project work estimates the solar radiation flux over Ibadan, a south-western city in Nigeria. The estimated models for the solar radiation over Ibadan are obtained for the period of ten years (1995 to 2004). The solar radia...

Indoor Gamma Dose Rate Exposure Levels in the Faculty of Science, University of Ibadan

Building materials are one of the potential sources of indoor radioactivity because of the naturally occuring radionuclides in them. Exposure to indoor ionizing radiation, like gamma radiation, results in critical health challenges. This work was designed to assess the indoor gamma dose rate level following the renovations of offices of lecturers in Faculty of Science, University of Ibadan using RDS-30 Survey meter. Measurements were made at 110 locations after renovations and in some selecte...

Zones of Inhibition and Molecular Docking (In-silico Approach) of Piptadeniastrum africanum Extracts on Clinical and Multiple Antibiotic Resistant Isolates

The use of plants as medicines is an ancient practice common to especially Nigeria and Africa at large. The purpose of this research work is to evaluate the zones of inhibition, phytochemical screening and molecular docking (In-silico Approach) of Piptadeniastrum africanum against selected clinical and multiple antibiotic resistant isolates. Using agar well diffusion method, the antimicrobial activity of the stem bark and leaf extracts of Piptadeniastrum africanum was assayed against Escheric...

Antibacterial Activity of Garlic (ALLIUM SATIVUM) on Staphylococcus aureus and Escherichia coli

The study was carried out to evaluate the antibacterial potential of ethanolic and aqueous extracts of Garlic on Staphylococcus aureus and Escherichia coli by serial dilution in molten agar. The result of the study showed that both aqueous and ethanolic extracts inhibited the growth of the test organisms and hence their potential for the development of novel classes of antibiotics. 

Radon soil–gas as a geological mapping tool: case study from basement complex of Nigeria

Abstract In an effort to quantify thegeogenic radon soil–gas potentialand appraise the use of radon tech-nique as a geological mapping toolin a crystalline basement rock terrain of Ile–Ife Nigeria, radon measure-ment concentration were made usinga radon detector instrument (EDARD-200) that measures radon isotopes by a scintillator cell coupled to a photo multiplier tube. The data were collected from soils derived from three different lithologic rock units. The observed values were then...

ABSTRACT           In the period of the 1970’s, Agriculture was the main stay of the Nigeria economy. The oil boom of 1970’s brought about a gradual shift from agriculture to crude oil making Nigeria to depend heavily on petroleum as main source of foreign exchange earnings. Agriculture sector which use to be the back bone of the economy was rendered competitive over time. The crux of this study is to analyze the revenue generated from selected non-oil produce in Nig...

ABSTRACTCucumber has been an essential vegetable crop in the world being affected by Pythium, fusariium and phythophtora. Root and stem rot of cucumber (Cucumis sativus), caused by Fusarium oxysporum f. sp. radicis-cucumerinum, is a new catastrophic disease of greenhouse crops in Greece and some other countries Fusarium oxysporum causes rotting of roots, lower stems and pythium also causes seedling damping off which is widely spread across cropping soils. Fusarium root and stem rot occur most...
