Food microbiology is the study of the microorganisms that inhabit, create, or contaminate food. Microbes are being used for the production of foods, food supplements and food ingredients. Microorganisms are widely used in fermentative production, processing, and preservation of various kinds of foods and beverages. Microorganisms are also responsible for food spoilage and food poisoning which result in loss of food products and also cause damage to human and animal health causing health and economic losses. Studying the food microbes and the effects of microbial contamination is vital to various food safety, production, processing, preservation, and storage aspects.

Instructor bio

Dr. Niranjan Raj S

Department of Studies Microbiology Karnataka State Open University Mukthagangotri
I, Dr. Niranjan Raj S., Principal Investigator for Food Microbiology course under Massive Open Online Courses (MOOCs), am currently heading the Department of Studies in Microbiology at the Karnataka State Open University, Mysore, and have completed my M.Sc., M.Phil. and Ph.D. from University of Mysore and have 18 years of post-graduate teaching/research experience. I am the course coordinator for M.Sc. Microbiology at KSOU. During the last two decades I have mainly worked on basic and advanced aspects of plant pathology with particular reference to host-pathogen interactions and plant disease management. I have investigated the applicability of induced systemic resistance and biological control strategies for the effective management of downy mildew disease of pearl millet. My research contributions in the field of biochemical, molecular and biotechnological aspects of cereal downy mildew has helped in obtaining disease resistant pearl millet varieties and also in practice of disease free agriculture both at national and international levels. I have more than 70 publications to my credit in international peer reviewed journals of high impact factors. I also have two national patents. I have extended his expertise to many students, professionals and researchers though seminars, symposia and conferences and also by extending training courses for seed industry personnel, MSc., and MPhil., students and also summer research students who have availed my guidance for projects and course work. I have several merits and awards to his credit from various National and International Agencies like ICAR, UGC, DANIDA, ISCA, ASMPP, IPS, NESA, Hungarian Academy of Sciences, Auburn University etc.
