Course Synopsis

The course deals with an in-depth study into the area of Population genetics. It also involves passing across to the students how the principles of Mendelian genetics plays a role in Population genetics as well as the scope and areas of application of Population genetics. The practical aspect aims at developing skills of studying large populations of organisms and understanding the inherent genetic attributes possessed by these organisms and how it affects them and the outcome of research works. Topics to be covered include the statistical basis of population genetics, Gene and genotype frequencies, the Hardy-Weinberg principle and its uses, evolutionary processes, ecological and environmental genetics.

Course Synopsis

This course is designed to teach the special application of microbiology in storage practice. It is a practical applied course that focuses on assessing the microbiological quality of stored products, detecting and identifying spoilage organisms, and techniques of controlling microbial invasion of stored products and stores. The course will acquaint students with simple, basic investigative methods and maintaining microbiological standards which are necessary for good storage practice. The various tests that can be carried out while assessing the microbiological quality of products relevant in other applications of Biology will also be taught.

Course Synopsis

In general reference to stored products insects is generally made to coleopterous and lepidopterous pests whose damage to stored products is severe and persistence. This course is an eye opener for the students into different pests that affect stored product with emphasis on their biology, mode of infestation conditions that favour their developments in foods and how they can be controlled. It involves practical periods aimed at exposing the students to different pests affecting different stored products with emphasis on developmental identification of the various developmental stages. Topics to be covered include invertebrate pests of dried fish, meat and leather; invertebrate pest of cereal (weevils); invertebrate legumes and pulses; invertebrate pests of fruits and vegetables; invertebrate pests of roots and tubers; microorganisms of stored food; vertebrate pests and non chemical control of stored product pest.

Course Synopsis

Importance of storage. Storage losses. Factors affecting storage ability of commodities. Traditional and modern techniques used for the storage of diverse agricultural products with particular emphasis on dry and wet foods. Principles and methods of preservation of food, fish, wildlife products e.g drying, salting, refrigeration, canning etc. Quality of products in storage e.g degree of ripening, physical, biological and chemical characteristics of major stored products. Pre and Postharvest storage techniques under different ecological and climatic conditions.

Course Synopsis

This course is designed primarily for students in biology (storage technology option) and other biology related disciplines. The course explores the methods of food preservation and packaging, it enhances the knowledge of the students in microbiology of food preservation by heat processing, irradiation, low temperature storage, chemical preservatives, modification of atmosphere, control of water activity, and compartmentalization. The course will also teach insect contaminants as spoilage organism and the characteristics of packaging materials, migration of substances from packages into food and their health implications and packaging requirement for raw and processed food for local and foreign markets. The practical aspect of the course focuses demonstration of the effectiveness of the heat process on microorganisms (spores of fungi and the cells of bacteria isolated from food samples), development of chilling injuries on tropical fruits such as banana when stored in low temperature, storage of plantain or other tropical fruits in modified atmosphere and the results compared with the effect of the low temperature storage of such fruits. The practical aspect of the course will also teach the basic characteristics of the packaging materials of the import products, export products and the local products. The understanding of the rationale behind the practical procedures will enhance the student’s ability to design their own procedures if necessary as they advance to higher levels.

Course Synopsis

MCB 401 is a course that will help student appreciate the relevance of microorganisms in the production of some useful human products. This course will describe microorganisms of industrial importance as a factory in miniature. The initial fear that most students have that microorganisms can only cause sicknesses and diseases will be dispelled. The isolation, identification and conditions under which microorganisms can produce various products will be studied.
