Molecular marker analysis of F1 progenies and their parents for carotenoids inheritance in African cassava (Manihot esculenta Crantz)

Cassava genotypes were assessed at genomic DNA level to estimate the genetic diversity within and between them using 36 simple sequence repeat markers (SSR). One hundred and forty-seven (147) F1 progenies derived from crosses amongst the parental genotypes were used to determine the association between three SSR markers and beta-carotene content in cassava. For the diversity study, a total of 131 alleles with an average...

Effects of fermentation and extrusion on the proximate composition and organoleptic properties of sorghum-soya blend

The effect of extrusion and fermentation on the proximate composition and organoleptic properties of six combinations (100:0, 90:10, 80:20, 70:30, 60:40 and 50:50) of sorghum - soya blend were investigated. A total number of 19 microorganisms were isolated during the fermentation of sorghum-soya extrudates; these comprise of twelve (12) bacteria, four (4) yeast and three (3) moulds. They include Flavobacterium rigense,...

Sugar cane juice for polyhydroxyalkanoate (PHA) production by batch fermentation

Clarified sugar cane juice was evaluated as an alternative substrate for the batch production of polyhydroxyalkanoates (PHAs) by Alcaligenes latus, and a mineral salt broth was used as the control. The study included the physicochemical characterization of the juice, measurement of the fermentation kinetic parameters and identification of the polymer type by attenuated total reflectance Fourier transform infrared...

Induced spawning of Liza ramada using three different protocols of hormones with respect to their effects on egg quality

Two intramuscular injection strategies were performed for females of Liza ramada. The first strategy was applied with two injections; priming dose (CPE, 20 mg per fish). Then, the resolving dose (200 µg/kg of LHRH-a) was given after 24 h later. The second strategy was applied with two injections; the priming dose (3500 IU HCG per fish). Then, the resolving dose (200 µg/kg LHRH-a) was given after 24 h later....

Pharmacognostic evaluation and antisickling activity of the leaves of Securinega virosa Roxb. ex Willd. (Euphorbiaceae)

Securinega virosa (Euphorbiaceae) together with condiments from natural sources serve as antisickling remedies in Nigeria. This study was aimed at establishing the pharmacognostic profile as well as the antisickling activity of the leaves of S. virosa Roxb. ex Willd (Euphorbiaceae). Evaluation of the fresh, powdered and anatomical sections of the leaves were carried out to determine the macromorphological,...
