Institute of Industrial Biotechnology (IIB)

Institute of Industrial Bio-Technology

INTRODUCTION

The 21st century is envisioned as an era of Biotechnology and Applied Microbiology. Remarkable achievements have been made in the field of science in general, and life sciences in particular, during recent decades. The industrial biotechnology is one of the promising fields that have the potential to address some of the world’s greatest challenges, such as feeding a growing population and offering new alternatives to our scarce natural resources. Although there is a long way to go, if industrial biotechnology reaches its full potential it has the potential to impact the world.

The products of industrial biotechnology include a variety of everyday products such as alcoholic beverages, organic acids, enzymes, detergents, amino acids, baker’s yeast, bioplastics, health care products, biofuel and biodiesel. The impact of industrial biotechnology improving the quality of life is obvious by the fact that the global biotechnology industry has grown to reach revenue of $338 billion in 2018. The global biotechnology market is expected to reach $727.1 billion by 2025.

Realizing the immense economic potential of industrial biotechnology, Institute of Industrial Biotechnology (IIB) was set up in 2005 at GC University Lahore under a grant of Rs. 48.087 million from Higher Education Commission (HEC) of Pakistan. IIB is a vibrant institute which has gained a good repute in the University and the society due to its strong commitment to excellence both in research and teaching during the last five years.

The aim of IIB is to develop indigenous experts in Microbiology and Biotechnology. This will increase employment opportunities for qualified students both in industrial research and development markets. The manpower will be highly instrumental in developing in-house technologies for the production of various industrial products at National and International level. The Institute has adopted an integrated approach embracing the view that tomorrow’s breakthroughs are likely to occur at the interface of traditional and advanced biological subdivisions. The aim is well served by the amalgamation of all the related disciplines of Microbiology and Biotechnology. The learning process at IIB comprises of a combination of lectures (theory & practical), seminars/presentations, research projects, internships in various industries, industrial study tours, self-directed readings and independent studies.

The Mission statement of IIB is the: “Initiate enthusiastic endeavors to establish strong foundation for pursuing excellence in the rapidly advancing integrated fields of Biotechnology and Microbiology.”

Programme Aim
The aim of IIB is to develop indigenous manpower experts in the fields of Microbiology and Biotechnology. This will increase employment opportunities for qualified students both in industrial research and development markets.
