Degradation kinetics of 2,4-dichlorophenoxyacetic and atrazine by Trametes versicolor (L.:Fr.) Pilát
The degradation kinetics of different sources of 2,4-dichlorophenoxyacetic (2,4-D) and atrazine by the natural strain Mo008 of the basidiomycete fungus Trametes versicolor (L.:Fr.) Pilát was studied, knowing that in this process the strain used produces an enzyme complex composed of manganese peroxidase (MnP), lignin peroxidase (LiP) and laccase, and the response on the global consumption rate and yield is...

Isolation and characterization of Ralstonia solanacearum strains causing bacterial wilt of potato in Nakuru County of Kenya
In Africa, cultivation of potato (Solanum tuberosum) represents an important food source and income generation. However, its productivity is constrained by biotic and abiotic stresses. Bacterial wilt caused by Ralstonia solanacearum is an important constraint to the world potato industry. In Kenya, the disease affects 77% of potato farms causing yield losses of up to 100%. Control methods are limited mainly due to the...

Dynamics of the concentration of the hormones triiodothyronine and thyroxine at the beginning of the reproductive season and the effect of application of iodine in Nelore heifers bred in pasture
The aim of this study was to evaluate the dynamics of triiodothyronine (T3) and thyroxine (T4) hormones, their relation with body condition score (BCS) and reproductive stage of 248 Nelore heifers, and the effect of iodine application on the induction of cyclicity of 217 anoestrus heifers in pasture at the beginning of the reproductive season. At day zero (D0), an assessment of the BCS was performed. An examination of...

Comparison of antimicrobial properties of two spices commonly consumed in Nigeria and effect of temperature on their antioxidant properties
The study compared the antimicrobial activities of essential oils (EOs) from Piper guineense (Uziza) and Xylopica aethiopica (Uda) using diffusion and dilution assays, and evaluated their antioxidant properties at different temperatures. Comparison of the antimicrobial activities was determined using well-in-agar diffusion, disc diffusion and broth dilution methods against Escherichia coli, Salmonella sp and Bacillus...
