Optimised germination protocol for jackfruit seeds and evaluation of methods for extraction of DNA suitable for genetic analysis
(African Crop Science Society, 2022-08-18)Jackfruit (Artocarpus heterophyllus) is an underutilised plant that is promising in curbing food and nutritional security in sub-Saharan Africa. However, high level of secondary metabolites in its tissues significantly ... -
Optimising fermentation time in black tea manufacture
(Elsevier, 1986)A comparative study using in-line theaflavins analysis (ILTF), theaflavins of made-tea analysis (TFMT) and tasters' evaluations, to optimise fermentation during tea manufacture, was carried out. All methods obeyed a quadratic ... -
Optimization of biodiesel synthesis from Jatropha curcas oil using kaolin derived zeolite Na–X as a catalyst
(Royal Society of Chemistry, 2022)Biodiesel is an alternative renewable green fuel obtainable from the reaction of plant or animal oil with a low molecular weight alcohol in the presence of a catalyst. However, the cost of its production remains high due ... -
Optimization of Bioethanol Production from Sweet Sorghum Stalk (Sorghum bicolor (l.) Moench) Juice Using Response Surface Method
(Science publishing group, 2022)The use of fossil fuel as a source of energy has been unsustainable and has adverse effects to the environment. Bioethanol is a suitable alternative due to its exceptional properties. Bioethanol production can be done ... -
Optimization of growth conditions and characterization of enzymatic activity of selected novel Streptomyces species from Kenyan soils
(Scientific Conference Proceedings, 2012-06-14)This study was aimed at unveiling and assessing protease, esterase, amylase and lipase enzymes from selected novel Streptomyces species with biotechnological interest. Four Streptomyces isolates from Jomo Kenyatta University ... -
Optimization of parameters for bio-ethanol production from sweet sorghum (Sorghum bicolor (L.) Moench) stalk juice and finger millet malt using Taguchi method
(2024)Bio-ethanol is a promising renewable energy but its production is expensive from high cost of feedstocks. In this study, sweet sorghum (Sorghum bicolor (L.) Moench) stalk juice was investigated for bio-ethanol production. ... -
Optimizing production of biodiesel catalysed by chemically tuned natural zeolites
(Elsevier, 2018-12-31)The twin crises of fossil fuel depletion and environmental degradation coupled with their unpredictable prices is a reality. Biodiesel is a promising, viable and environmentally friendly alternative. However, production ... -
Optimizing Zeolitic Catalysis for Environmental Remediation
(John Wiley & Sons, Inc., 2015-05-01)This chapter discusses the effects of chemical and physical properties of zeolites as they affect the catalytic efficacy and applications of the zeolites in environmental remediation. Heterogeneous catalysts, where zeolites ... -
Option Pricing of an Asset with Seasonal and Periodic Supply
(International Journal of Multidisciplinary Sciences and Engineering, 2014-12-12)In option pricing the rate of change of asset price with time can be viewed to be directly proportional to the Walrasian [6] excess demand. Scholars such as Jacques [3] and Onyango [4], have used the excess demand concept ... -
