Molecular identification of tsetse fly (Diptera: Glossinidae) species based on mitochondrial DNA (COII and CytB) sequences
Tsetse fly (Diptera: Glossinidae) anti-vector measures are reliant upon accurate identification of species and their subpopulations. Two species were studied, Glossina palpalis palpalis and Glossina morsitans submorsitans using two mitochondrial DNA: cytochrome oxidase subunit II (COII) and cytochrome b (CytB). Sequencing data were used to perform phylogenetic analysis of the two reared species together with other...

Determination of long-term effects of consecutive effective fresh chicken manure with solarization and verticillium wilt (Verticillium dahlia Klebb) on weed and its control in egg plant
The aim of the study was to determine the weed density and the most economical way of weed control in eggplant (Solanum melongena) fields contaminated with Verticillium dahliae (Kleb) after the application of fresh chicken manure and solarization in the second year as the same crop was grown. The effect of solarization on weed and the labor need in weed control continued in a diminishing way in the consecutive...

Pleurotus pulmonarius cultivation on amended palm press fibre waste
In the last few decades, rapid global demand for edible oils has resulted in a significant increase in the land area of oil crop cultivation. In the process of extraction of palm oil from oil palm fruit, biomass materials such as palm pressed fibre (PPF) are generated as waste products. This research was undertaken to evaluate the use of palm pressed fibres as the substrates for the cultivation of Pleurotus pulmonarius...

Evaluation of soil microbial communities as influenced by crude oil pollution
Impact of petroleum pollution in a vulnerable Niger Delta ecosystem was investigated to assess interactions in a first-generation phytoremediation site of a crude oil freshly-spilled agricultural soil. Community-level approach for assessing patterns of sole carbon-source utilization by mixed microbial samples was employed to differentiate spatial and temporal changes in the soil microbial communities. Genetic...

Characterization of the dominant microorganisms responsible for the fermentation of dehulled maize grains into nsiho in Ghana
Nsiho (white kenkey) is a type of kenkey, a sour stiff dumpling, produced from fermented maize meal in Ghana. The dominant microorganisms responsible for the fermentation of nsiho were characterized by analysing samples from four traditional production sites at Anum in the Eastern Region of Ghana. During 48 h of steeping dehulled maize grains, the pH values decreased from 6.05 to 5.93 to 3.59 to 3.55, whilst titratable...

The nutritional quality of Spirulina platensis of Tamenrasset, Algeria
Spirulina platensis, a blue green microalga, has been used since ancient times as a source of food because of its high protein content (65%) and nutritional value. Lipids isolated from S. platensis have been shown to contain high levels of polyunsaturated fatty acids, including linolenic acid which is a precursor of arachidonic acid; this cyanobacteria contains, also, several kinds of sterols. The aim of this study is...

Inclusion of sweet sorghum flour in bread formulations
Sweet sorghum (Sorghum bicolor L. Moench) has been studied as an additional source of raw material for production or partial replacement of foods due to its high fiber concentration. Its consumption is associated with the prevention of some diseases and nutritional benefits. The aim of this study was to evaluate the partial replacement of wheat flour by sweet sorghum flour in bread formulations in order to characterize...

Critical evaluation of proteomic protocols for passion fruit (Passiflora edulis Sims) leaves, a crop with juice market benefits
Passion fruit grows practically all over Brazilian territory; its production is largely destined to juice industry and expanding to overseas markets. The suitability of four protein extraction protocols for plant proteome was investigated to determine the best choice for studies concerning passion fruit leaf proteins. Trichloroacetic acid (TCA)/acetone extraction; isoelectric focusing (IEF) buffer extraction; phenol...

Analysis of alkaloid phytochemical compounds in the ethanolic extract of Datura stramonium and evaluation of antimicrobial activity
The aim of this study was to assess the compounds of alkaloids extracts from the leaves of Datura stramonium, which can be the basis for the synthesis of new antibiotics. In this study, the alkaloid compounds of D. stramonium have been evaluated. The chemical compositions of the leaves of ethanolic extract of D. stramonium were investigated using gas chromatography-mass specroscopy. Gc-MS analysis of alkaloid leaves...

Effects of manganese, 2,5-xylidine, veratryl alcohol and tween 80 on the production of ligninolytic enzymes by Ceriporiopsis subvermispora
The effects of adding manganese, 2,5-xylidine, veratryl alcohol and Tween 80 in a culture medium used for the production of ligninolytic enzymes by polyurethane foam-immobilized Ceriporiopsis subvermispora were studied. While 11 ppm Mn2+ promoted the highest maximum activity of manganese peroxidase (108.0 ± 43.3 U/L, in the 6th day of cultivation), the medium without manganese led to the highest maximum...
