Lipase and esterase activities of lactic acid bacteria isolated from different biotopes
The lipolytic and esterase activities of fifteen strains of lactic acid bacteria isolated from different biotopes of Algeria and Mauritania were tested on MRS medium supplemented with lipidic substrates. Five of them showed maximum activity in the presence of tributyrin; the activity is therefore a tributyrin esterase. These strains were identified by MALDI-TOF in Enterococcus faecium and Enterococcus durans. The study...

Genetic variation via SSR polymorphic information content and ecological distribution of Nigerian sesame
Sesame (Sesamum indicum L.) of the family Pedaliaceae is an important and old oil crop that is cultivated mainly in the tropical and subtropical regions of Asia and Africa for several economic values. Several molecular markers have been employed to study the genetic diversity of this important crop. The study focused on the genetic diversity through polymorphism information content (PIC) by the use of Simple Sequence...

Genetic diversity for immature pod traits in Ethiopian cowpea [Vigna unguiculata (L.) Walp.] landrace collections
This study was undertaken to evaluate the extent and pattern of genetic diversity for immature pod traits in Ethiopia cowpea landrace collections. Eighty one landraces and improved cultivars were tested in a 9 x 9 simple lattice design. Analysis of variance revealed highly significant (P<0.01) or significant (p<0.05) differences among the genotypes for all traits. The first four principal components were able to...

Algae: Potential biotechnological source in the Arabian Gulf
Arabian Gulf is characterized by being nutrient-rich, which contributes to the biodiversity of marine macro- and microalgae. Marine algae are a potentially prolific source of many valuable products that may represent useful leads in developing the quality of human life. The studies on the bioactivity of marine algae in the Arabian Gulf region are very recent; thus, there are not many studies on this field. This review...

Estimates of genetic variability, heritability and genetic advance for agronomic and yield traits in soybean (Glycine max L.)
A study with 20 soybean genotypes was conducted in 2015 and 2016 to determine the genetic variability, heritability and genetic advance for some agronomic and yield traits in some soybean genotypes for selection criteria in a breeding programme. The field experiments were laid out in a randomized complete block design (RCBD) and replicated three times. Analysis of variance (ANOVA) revealed significant variation among...

Effects of Ambrosia maritima (Damsissa) ethanolic extract on phenylhydrazine hydrochloride-induced anaemia in rabbits (Lepus cuniculus)
This work was performed to evaluate the anti-anaemic activity of the ethanolic extract of Ambrosia maritima (Damsissa) in phenylhydrazine hydrochloride (PHZ)-induced anaemia in rabbits. Twenty-five adult rabbits of different sexes were equally divided into 5 groups. The induction of anaemia was performed by subcutaneous administration of PHZ at a dose of 30 mg/kg body weight and maintained a dose of 15 mg/kg body...

Descriptive sensory evaluation of “gari†produced from fermentation of cassava using some selected Rhizopus species
Two local varieties of cassava (Manihot esculenta crantz) pulps named “okoiyawo” and “odongbo” were fermented with pure Rhizopus oligosporus, R. nigricans and R. oryzae. The products were subsequently processed in to “gari” (a roasted fermented cassava meal), the form in which it is popularly consumed in Nigeria. The selected process variables are cassava varieties, starter culture...
