Meet on emerging trends in bioprocess, food processing

THE KEY steps in mass production of a bio-metabolite are selection of appropriate media components or concentrations and optimum environmental condition to over produce a particular metabolite. This was stated by Dr Ashok Kumar Srivastava professor in the biochemical engineering and biotechnology at the Indian Institute of Technology delhi while delivering the key note address Genesis-2006 .

THE KEY steps in mass production of a bio-metabolite are selection of appropriate media components or concentrations and optimum environmental condition to over produce a particular metabolite.

This was stated by Dr Ashok Kumar Srivastava professor in the biochemical engineering and biotechnology at the Indian Institute of Technology delhi while delivering the key note address Genesis-2006, a national seminar on ‘Emerging trends in bioprocess and food processing industries’ held at the Harcourt Butler Technological Institute (HBTI) here on Saturday. The seminar has been jointly organized by the Association of Biochemical Engineers and Food Technologists (ABEFT) and the Department of Biochemical Engineering and Food Technology of the HBTI.

He said the process was followed by the selection of small-scale bioreactor and its mode of operation to produce economically important metabolite at high yields and productivities. The optimization of small scale is facilitated by proper online or line monitoring techniques and their usages for feed forward and back control strategies.

He said that different traditional methods of process optimization protocols were replaced by the newer protocols and procedures in the present times Engineering optimizations were more logical and scientific. The mathematical models served as a useful tool to minimize experiments and optimize fermentation. Besides, the newer analytical tools were being made available to monitor the state of fermentation on line to ensure implementation of feed back control algorithms. However, novel reactor designs have been proposed to facilitate the cultivation by plant and animal cells to produce interesting fermentation metabolite and medicinally important compound, he added.

Dwelling upon ‘catalyzed synthesis of oligosaccharide based nuetraceuticals’ Dr Subhash Chandra of the IIT Delhi said that in recent years there was a growing concern among consumers about their health care, seeking low cost, alternative beneficial products. People are looking for ways to live healthier life.

Nutraceuticals are essentially physiologically active molecules that have the ability to provide specific health benefits and are used as food supplements.

He said various products are claimed not only to reduce the risk of cancer and heart disease but also to control hypertension, high cholesterol, excessive weight, osteoporosis, diabetes, arthritis, cataracts, constipation, insomnia and headaches.

S.K. Mishra, from Bajaj Hndustan Ltd, said that use of micro organisms has been exploited since ancient times but the recent understanding of microbiology, biochemistry and molecular biology has given boost for rapid advancement of field of biotechnology area of medical sciences, agriculture and industrial chemicals.

Earlier, HBTI Director Dr RP Singh inaugurated the seminar and Professor VK Jain gave a brief history of the department.
