MIBI 43036
>< Type/Status : Compulsory
>< Title : Microbial Technology and Environmental
Microbiology
>< Pre-requisite : All MIBI core course units
of the B. Sc. General Degree programme
>< Objectives : At the end of the course
unit, the students will be able to demonstrate the knowledge and understanding
of
• basic microbial growth kinetics in relation to
their product formations,
• the industrial microorganisms and their importance,
• the role of microorganisms in the production of
industrial chemicals, pharmaceuticals, food products,
• the natural microbial activities that are essential
for controlling environmental pollution in water & soil, and their contributions
to clean the environment under different conditions,
• the technology used to minimize the production
waste in selected industries.
>< Course content:
Microbial technology:
Biochemical engineering: Stoichiometry of Microbial processes, Bioprocess
kinetics; Models of microbial growth, (Monod); Kinetics of Batch fermentation,
Continuous fermentation and Fed-batch fermentation system; Productivity in fermentation
systems.
Microbial process development, Selection, and Maintenance of industrially important
microorganisms. Media formulation and the characteristics of the large scale
fermentation. Scale up of the fermentation process. Downstream processing and
products recovery.
Fermentation industry: Production of organic acids, amino acid
enzymes, bio-ethanol, solvents, pharmaceuticals and other health care products.
Cosmetic Microbiology. Economics in biotechnology and fermentation processes.
Management of microbiological quality of selected products.
Environmental Microbiology:
Microorganisms in their natural habitats and microbial loops, Bio deterioration:
paper, wood, paint, textile and metal corrosion: Bio-leaching of metals, Biodegradation
of xenobiotics, Methane and methanogenesis. Waste biotechnology: Water and wastewater
management; water and wastewater treatment plants: domestic and industrial waste
management; sewage treatment strategies, Bioaugmentation, Composting-substrate,
process operation and control process economics. Waste exploitation for higher
value products, exploitation of industrial waster streams e.g. SCP and alcohol,
xanthan. Microbial quality assurance procedures and ISO guideline for environmental
management. Cleaner production technology.
>< Methodology: Throughout
the year course with a combination of lectures and tutorials.
>< Scheme of Evaluation: 100% end of course
examination.
