Enzootic bovine leukosis and the risk to human health
The bovine leukemia virus (BLV) was first reported as enzootic bovine lymphosarcoma in Eastern Europe in the late 19th century, highlighted by the presence of slightly yellow nodules in the enlarged spleen of cattle. It was believed to be an infectious disease because it spreaded through the herds. With changes observed in sensitivity of diagnostic techniques, the opinion that “BLV does not infect humans”...

In vitro anti-tyrosinase and anti-elastase activity of collagen from sea cucumber (Holothuria leucospilota)
Collagen is the main structural component of connective tissues in vertebral and invertebral animal tissues and organs. The collagen isolated from the body wall of sea cucumber (Holothuria lecospilota) can be used in the pharmaceutical field. The research aimed at isolating collagen from the sea cucumber body wall and testing the anti-tyrosinase and anti-elastase activity. This was done by isolation of collagen by...

Production of invertase from Saccharomyces cerevisiae Angel using date syrup as a cost effective carbon source
Invertase (β-fructofuranosidase) finds major applications in food, cosmetics, and pharmaceutical industries. In the present study, fermentation conditions for invertase production from Saccharomyces cerevisiae Angel using date syrup in shake flask were investigated. The effect of time period (0-96 h), carbon sources (sucrose, date syrup, maltose, galactose, and glucose), nitrogen sources including yeast extract,...

Assessment of genetic diversity among cultivated Pearl millet (Pennisetum glaucum, Poaceae) accessions from Benin, West Africa
Simple sequence repeat (SSR) molecular markers were used for genetic diversity analysis and population structure of the cultivated Pearl millet in Benin, West Africa. In order to assess the level of genetic diversity, 14 polymorphic SSR markers were used to screen 114 accessions from different agro-ecological zones in Benin. SSR markers were found to reveal a total of 57 alleles with an average of 4.071 allele per...

Enhancing the production of syringomycin E in Pseudomonas syringae pv syringae by random mutagenesis and molecular characterization of the SyrB1 gene
Syringomycin E (SRE) is a phytotoxin produced by Pseudomonas syringae pv syringae with high potential as a safe and effective therapy for the control of human fungal infections and as a preservative for the food industry. In this study, 27 strains of P. syringae pv syringae were isolated from plums, potatoes, apricots and peaches, of which P. syringae pv syringae 120 (PS120) showed the highest SRE production levels....

The impact of salinity stress on morphological and anatomical aspect of water hyssop Bacopa monnieri (L.) Wettst grown in vitro
This study was conducted at Marine Science Center, Basrah University, Basrah, Iraq during the period of 2015 to 2016. In the present work, we used NaCl and polyethylene glycol (PEG) to induced abiotic stress in vitro. Results show that high shoot numbers (24) were produced on MS (solid) medium enriched with 0.8 g/L NaCl in addition to cytokinins while, inclusion of drought agent PEG to proliferation medium (solid and...

Determination of proximate and mineral compositions of Moringa oleifera and Moringa stenopetala leaves cultivated in Arbaminch Zuria and Konso, Ethiopia
This study presents the proximate and mineral composition analysis of Moringa oleifera and Moringa stenopetala leaves collected from two different agro-ecological zones namely Arbaminch Zuria and Konso in Southern Nation Nationalities and Peoples Region (SNNPR), Ethiopia. M. oleifera and M. stenopetala leaves were collected using random sampling method from four sampling sites namely Secha, Karat, Sikela, Gato. Before...

Effects of activated charcoal on medium-term conservation of yam (Dioscorea spp.) cultivated in Benin
The effects of activated charcoal were tested on medium term conservation of yams cultivated through tissue culture techniques. Galzy glutamine basic medium and that supplemented with 3 g/l activated charcoal were used. Growth parameters such as number of leaves, height of stem, number of nodes and length of the main root are evaluated on plantlets after 20 months. The test T of Student Newman and Keuls (SNK) with two...
