Research ArticleOpen accessIn the abstractControlled Release Behaviors of Tribenuron Methyl Herbicide and Potassium Nitrate Fertilizer from Natural Polymer Blended Poly(Vinyl Alcohol) Hydrogel MicrospheresFawzi Habeeb Jabrail, Wajeeh Mohammed Jamil, Maher Zeki Elsabee, Kailash Chandra GuptaPolyvinyl Alcohol (PVA) hydrogel microspheres for controlled release of fertilizer (KNO3) and Tribenuron Methyl Herbicide (TBM) were prepared by blending the naturally occurring Alginate (AL) and Pectin (PE). The cross-linking in PVA hydrogel microspheres was carried out by varying the amount of glutaraldehyde from 0.5-1.0 wt%. To control the loading and release properties of PVA hydrogel microspheres, a small amount … …American Journal of Applied Sciences, Vol. 16, Issue 5 · 13 Jul 2019 · 7,677 accessesView PDFCite
Literature ReviewOpen accessIn the abstractSoya Beans Production in Zambia: Opportunities and ChallengesBrivery SiamabeleThe soya bean production opens doors of opportunities for Zambian farmers. Notably, the climate in Zambia is largely favourable for soya production and the arable land is vast enough to accommodate future expansion. Most importantly, soya is a very profitable crop. On the other hand, there are some challenges which affect soya production such as poor soils aggravated by low … …American Journal of Agricultural and Biological Sciences, Vol. 14, Issue 1 · 15 May 2019 · 13,458 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh Level of Nicotianamine Synthase (NAS3) and Natural Resistance Associated Macrophage Protein (NRAMP4) Gene Transcription Induced by Potassium Nitrate in Trembling Aspen (Populus tremuloides)Karolina M. Czajka, Kabwe NkongoloChanges in gene transcription in response to excess metal concentrations have been reported in many organisms, including yeast, microorganisms and plants. Most investigations on the effects of nickel toxicity in plants use commercial salts whose effects have not been analyzed in detail. The main objective of the present study was to determine the effects of different doses of nickel nitrate … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 15 Jul 2018 · 10,885 accessesView PDFCite
Research ArticleOpen accessIn the abstractBrevibacillus Thermoruber 9X-GLC, Bacteria Isolated from Hot Compost, Producer of a Beta-Glucosidase Resistant to Glucose InhibitionAlejandro Sosa-Peinado, María Eugenia Hidalgo-Lara, Miguel Ángel Plascencia-Espinosa et al.The thermotolerant strain Brevibacillus thermoruber 9X-GLC produces large amounts of β-D-glucosidase and cellobiohydrolase when grown on cellobiose and avicel. 9X-GLC was isolated from hot compost of sugarcane bagasse and filter mud and selected for its high enzymatic activity from a Bacilli collection of 77 isolates from soils and compost. Culture supernatants and ultrafiltered concentrates from shaken flask cultures of 9X-GLC … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 20 Oct 2017 · 8,156 accessesView PDFCite
