Yield coefficient for the growth of Pseudomonas sp. AQ5-04 at various concentrations of phenol

Phenol is widely used by many industries in Malaysia, and is one of the highly toxic environmental pollutants with levels exceeding the regulatory standard that have been reported in Malaysia. A phenol-degrading bacterium; Pseudomonas sp. AQ5-04, a metabolically versatile xenobiotic-degrading bacterium, has been isolated from a local contaminated site. The bacterium was able to withstand a high concentration of phenol....

Genetic diversity of Faidherbia albida populations in the Sudano Sahelian region of Cameroon, using simple sequence repeat (SSR) markers

Faidherbia albida (DEL.) A. Chev is widely grown in the northern region of Cameroon because of its many benefits to local communities. However, droughts and deforestation have led to decreases in the abundance of this species, increasing the need to identify improved genotypes for conservation, management, and breeding. The genetic diversity of F. albida in nine populations from the Sudano-Sahelian region of northern...

Readiness of the Nigerian public for the introduction of genetically modified crops into the food market

Genetically modified crops (GM crops) have gained wide attention over the years some GM crops have been undergoing field trials in Nigeria, but they have not proceeded to commercial cultivation due to the absence of regulatory law. The biosafety act was passed into law in 2015 and the presence of this law, can see to the progression of the GM crops from field trials to commercialization. This study investigated the...

Genetic diversity analysis among soybean genotypes using SSR markers in Uganda

The assessment of genetic diversity among improved crop germplasm can facilitate the expansion of the genetic base for crop improvement in breeding program. However, little effort has been made to assess the level of genetic relatedness among released varieties and elite soybean [Glycine max (L.) Merr.] genotypes. The objective of this study was to determine the degree of genetic diversity that exists among released and...

Evaluation of poultry waste medium and light quality for lipid accumulation in fresh water green microalgae isolate

The global quest for production of biofuel at a competitive price with fossil fuel has driven research to the exploration of organic waste as a cost-effective growth medium for microalgal biodiesel production. In this study, poultry waste extract (PWE) was explored as growth medium for efficient biomass and some intracellular content accumulation by Chlorella sp. isolate for eight days. The analysis of the poultry waste...

Next generation sequencing as a method to verify virus elimination using heat treatment and meristem tip culture in the five most widely used sweet potato varieties in Ethiopia

Sweet potato (Ipomoea batatas L. Lam) has become one of the staple crops in Africa in the last 20 years. In Ethiopia, sweet potato is the second most widely grown root crop and is the first regarding the production per hectare. Thus, there is a great demand of planting material throughout the country. Currently, planting material is usually obtained from own previous season harvest, local markets or from the neighboring...

Analysis of genetic diversity in four Sudanese provenances of Balanites aegyptiaca (L.) Del. based on random amplified polymorphic DNA (RAPD) marker

Balanites aegyptiaca (L.) Del. (Heglig) is a multipurpose tree with considerable potential. The wide range of environments under which it is growing suggests high pattern of variation among and within locations. The scrutiny was undertaken to assess genetic diversity among and within four geographical genotypes of Heglig growing naturally in four different regions of Sudan based on their seed performance using random...

Stabilisation potentials of the essential oils of Thymus vulgaris L., Cinnamomum zeylanicum B. and Mentha piperita L. on palm olein at accelerated storage

This study aims at bringing to light the preservative potential of essential oils of Thymus vulgaris, Cinnamomum zeylanicum and Mentha piperita in the stabilisation of lipids against oxidation. The essential oils were extracted by hydrodistillation and chemical composition were analysed by gas chromatography coupled with mass spectrometry. In vitro antioxidant potentials of the essential oils were tested by the 2,...

Response of catalase to drought in barley (Hordeum vulgare L.) seedlings and its purification

Drought induced oxidative stress triggers anti-oxidative system in cell to minimize oxidative damage where catalase plays vital role to neutralize H2O2. In this work, catalase activity was evaluated to examine the role of catalase in barley (Hordeum vulgare L.) seedlings under drought stress. As compared to control, catalase activity increased with decreasing soil moisture where 219% higher activity were recorded at 10%...

Diversity of arbuscular mycorrhizal fungi (AMF) and soils potential infectivity of Vachellia nilotica (L.) P.J.H. Hurter & Mabb. rhizosphere in Senegalese salt-affected soils

Vachellia nilotica, a multipurpose tree useful to rural populations, is often used to rehabilitate Senegalese salt-affected soils due to its salt-tolerance probably related to arbuscular mycorrhizal fungi (AMF) symbiosis. This work aimed to determine the AMF communities associated with V. nilotica rhizosphere in salt-affected soils and their potential infectivity. Soils were sampled from six sites in the...
