Investigation of Antifungal Activity of Green-Synthesized Silver Nanoparticles on Phytopathogenic Fungi

Oloyede A R.*, Ayedun E. O, Sonde O I, Akinduti P. A

Silver nanoparticles (SNPs) are nanoparticles of silver that are in the range of 1.0 and 100nm in size. They have unique antimicrobial properties which help in water sanitation and medical industries, but their potentials in agriculture have not been utilized. This study was conducted to investigate the effectiveness of SNPs synthesized using different concentrations of bitter leaf (Vernonia amygd...

Optimized Fermentation Process for Improved Bioethanol Production from Sweet and Bitter Cassava Processing Wastes

Obueh H.O*, Ikenebomeh, M. J,, Oshoma, C.E

Optimization of fermentation process for 72 h was carried out to determine the effect of pH (3 – 8), temperature (30°C – 50°C) and agitation rate (200 rpm – 500 rpm) on bioethanol production and microbial count using cassava variety samples. Bioethanol yield and microbial count were highest at pH 6, temperature 35°C and agitation rate of 300 rpm. The bacterial species had highest population cou...

Phylogenetic Analysis of Sulphidogenic Bacteria Isolated From Nigerian Crude Oil and Its Produce Water

Akinnibosun F. I.*, Lappin-Scott H. M

Phylogenetic analysis of sulphidogenic bacterial isolates from Nigerian Bonny light crude oil and its produce water samples was carried out following preliminary detection of the bacterial species. Samples were enriched in mixed carbon postgate’s (MCP) medium and incubated at 55 ºC for 28 days. DNA was extracted from isolated culture and amplified by Polymerase Chain Reaction (PCR) using 16S r...

Prevalence of Uropathogens in Diabetic Patients and their Antimicrobial Susceptibility Pattern

Akinnibosun F. I.*, Iriakpe, H. J

The prevalence of bacteria causing UTI in diabetic patients, as well as their susceptibility to commonly used antibiotics was investigated in Benin City. Bacteriological analysis involved standard biochemical tests and comparison of isolates’ characteristics with known taxa. Species isolated from the urine samples analysed were Escherichia coli, Staphylococcus aureus, Staphylococcus saprophytic...

Green Synthesis and Antibacterial Activity of Silver Nanoparticles From Extract of Leaves of Croton Zambesicus

Ahmed, R.N.*, Sani, A, Oluwo, O.N, Sule, I.O, Zakariyah, R.F

Silver nanoparticles (AgNPs) was synthesized using a combination of aqueous extract of Croton zambesicus and silver nitrate (AgNO3) solution to obtain various concentrations of 100mg/ml, 200mg/ml, 300mg/ml and 400mg/ml at 10mM. Characterization of the synthesized silver nanoparticle was done by UV-visible spectroscopy and Fourier Transform Infrared Spectroscopy (FTIR). Antimicrobial activity ag...
