Abstract

Water borne bacterial pathogens were isolated from sachet water vended in Ogbomoso, Oyo State, Nigeria. The isolates were characterized and identified as Bacillus subtilis, Bacillus alvei, Pseudomonas putida, Pseudomonas fluorescens, Bacillus cereus, Enterobacter aerogenes and Proteus mirabilis. The antibiotic susceptibility profile of the seven isolates was determined and it was discovered that 59.3% was found sensitive to the commercial antibiotic disc used while 40.7% was resistant. The effect of temperature, pH and sodium chloride concentration on the growth rate of isolates was investigated. It was found that as temperature of incubation increased from 50 to 80°C, the rate of growth of all the isolate decreased and as the pH of the growth medium increased from 3 to 9, the rate of growth of all the isolates also increased. As the concentration of sodium chloride increased from 2 to 5%, the rate of growth of isolates also reduced.

Key words: Bacillus subtilis , Bacillus alvei, Pseudomonas putida, Pseudomonas fluorescens, Bacillus cereus, Enterobacter aerogenes and Proteus mirabilis, sachet water, pH, temperature and sodium chloride.

Abstract

Several species of the Raphia palm exists and are largely confined to tropical Africa, south of the Sahara, from sea level of about 2000m altitude. In Nigeria, it is found in the south-south geopolitical zone. It provides material for furniture, house construction, food, clothing, edible oil, and so on. Raphia palm is one of the most useful palms economically. The Raphia palm leaves are the largest amongst the palms in Africa. It produces sap which is drunk by millions of people in Africa. Over the last decade, the sap has attracted a lot of research interest. Consequently, the sap has been preserved. Useful nutrients have been detected in the sap, which could play active roles in human physiology and health. Products from the sap have been developed, which could be rehydrated and drunk like the original sap. The products could also act as sweeteners in food preparations. Increased cultivation of the palm could provide good income for small, medium and large scale farmers, as every part of the palm is useful.

Key words: Raphia palm, origin, cultivation, products, palm sap/wine, physiological.

Abstract

The new green revolution is looking for a breakthrough in the world. Constructing C₄ rice based on good plant type is a reliable and effective approach to enhance photosynthetic efficiency in leaf. The paper discusses the significance, techniques, physiological characteristics and future research directions of transgenic rice with C₄ gene and makes some suggestions on breeding new cultivars with super-high yield and photosynthetic efficiency in high light intensity and high temperature area of China, especially in Africa.

Key words: Rice, C₄ photosynthesis gene, photosynthesis, physiological breeding.

Agriculture for sustainable food, energy and industrial development in the Sub-Saharan Africa: The case of Nigeria

Abstract 

Global economic recession and the concomitant increase in food prices, unemployment, dilapidated infrastructures and poor industrial growth call for a concerted effort at ensuring a strong and efficient agriculture to meet the demands of ever increasing Nigerian population. No meaningful development can be attained without recourse to modern agriculture since virtually all facets of human endeavour relies primarily on products or bye-products of agriculture. This work evaluated Nigerian agriculture, the past, present and the challenges vis-à-vis the Brazilian type of agriculture that fosters sustainable development in food and energy production. The main reason for the slow agricultural development in Nigeria despite the volumes of scientific information to engender improvement was traced to poor government involvement in agriculture at the level of policy formulation and implementation. The very poor approach to the adoption of appropriate technology and scientific information in agriculture has resulted to loss of arable upland soils to the forces of erosion and floods and increase in greenhouse gas emissions through indiscriminate felling of protection trees and bush burning. Therefore, in order to bridge the wide gap in agriculture between Nigeria and other developing economy like Brazil and China, there is urgent need for a sincere and pragmatic involvement of the government and other non-governmental organizations in agriculture, with the use of modern and appropriate technology such that enough biomass could be produced for sustainable food, energy and industrial development.
