Fertigation with domestic wastewater: Uses and implications

The use of wastewater in agriculture is an alternative means of reducing wastewater release into water sources. This process, known as fertigation is an opportunity to make use of organic matter and other nutrients in wastewater for agricultural productivity. The presence of organic matter in these effluents serves as biofertilizer. Since 19th century in Britain, fertigation had been widely accepted due to the scarcity...

Selection criteria for drought tolerance at the vegetative phase in early maturing maize

Identifying drought tolerant maize (Zea mays L.) at the vegetative stage is a meaningful effort at reducing cost and time of screening large number of maize genotypes for drought tolerance. The primary objectives of this study were to assess the effectiveness of vegetative traits in discriminating between drought tolerant and drought sensitive hybrids and to determine the stage at which the stress should be imposed to...

Isolation and molecular identification of yeast strains from “Rabilé” a starter of local fermented drink

“Rabilé” is dried yeast harvested from Sorghum beer, used as a traditional starter culture but more especially as ingredient in sauce and food cooking in Burkina Faso. The present study aimed to isolate and identify indigenous yeast flora of “Rabilé”. Standard microbiological process was carried out to value and isolate yeast in different samples of “Rabilé”...

Genetic linkage map of cowpea (Vigna unguiculata (L.) Walp) using SNP markers

Genetic linkage maps provide a genomic framework for quantitative trait loci identification applied in marker assisted selection breeding in crops with limited resources. It serves as a powerful tool to breeders for analysing the mode of inheritance of genes of interest and monitoring of the transmission of target genes from parents to progeny. Single nucleotide polymorphism (SNP) markers have a great influence on...

Isomaltulose production using free and immobilized Serratia plymuthica cells

Isomaltulose is a low cariogenic sweetener used as a substitute for sucrose in the food industry. In this study, isomaltulose production by Serratia plymuthica ATCC 15928 was performed using free and immobilized cells. Response Surface Methodology was employed to evaluate the influence of temperature, wet cell mass concentration and sucrose concentration during the conversion of sucrose into isomaltulose by free cells....

The use of Amazon fungus (Trametes sp.) in the production of cellulase and xylanase

In order to use the residue from the beneficiation of Brazil nuts (Bertholletia excelsa HBK) as substrate in solid-sate fermentation (SSF), in this work, the production of cellulase and xylanase by the fungus Trametes sp. was investigated, using the residue as a carbon source. Employing a 24-1 fractional experimental design, the influence of substrate moisture, nutrient addition and inoculum quantity on enzymatic...

Preliminary characterization of slow growing rhizobial strains isolated from Retama monosperma (L.) Boiss. root nodules from Northwest coast of Algeria

In this paper, we did some preliminary characterization of six slow growing rhizobial strains, isolated from Retama monosperma (L.) Boiss. root nodules sampled from 3 sites along the coast of Oran (CapeFalcon, Bousfer and MersElHadjadj) in Northwestern Algeria. Results of this study showed that all strains had a very slow growth rate in yeast malt (YM) agar medium, forming colonies less than 1 mm in diameter after seven...

Sero-epidemiology of bluetongue in Algerian ruminants

A total of 2871 blood samples were collected (450 cattle, 1932 sheep and 489 goats) from 225 randomly sampled herds between January and June 2014. Competitive enzyme-linked immunosorbent assay (C-ELISA) was used to detect antibodies from sera as an indicator of exposure to bluetongue virus (BTV). The results show an overall herd seroprevalence of 16.44% (95% CI 9.42-23.46); 21.3% (95% CI 17.1-25.6) for cattle and 13.33%...

Role of arbuscular mycorrhizal fungi in phytoremediation of heavy metals and effects on growth and biochemical activities of wheat (Triticum aestivum L.) plants in Zn contaminated soils

The increase of metals pollution in soil is a worldwide problem that affects the health of humans and environment. The use of green technology such as phytoremediation is one of the environmental friendly techniques, in which plants and other microbes are used to reduce the level of metals contaminants in soil and lower its uptake towards plants tissues. Studies report that a number of cereal crops such as wheat...

Physico chemical evaluation of coffee husk, wastes of enset (Enset ventricosum), vegetable and khat (Catha edulis) through vermicomposting employing an epigeic earthworm Dendrobaena veneta (Rosa, 1886)

The major objective of this 90 days vermicomposting work was to evaluate the performance of epigeic earthworms, Dendrobaena veneta, to alter and change four commonly dumped and littered solid wastes in Ethiopian cities and towns into a high quality vermicompost. The experiments were conducted in cylindrical plastic containers with 26 cm depth and 53 cm width under shade. All containers were perforated on the sides for...
