Dr. Neeraj Wadhwa, Professor joined the Department of Biotechnology at JIIT in 2002. She graduated in Zoology (Honours) from Fergusson College, University of Pune, and Masters in Zoology from Pune University. She did her PhD in 1995 from University of Delhi, where her research focus was to study the post-transcriptional and post-translational modification in Plant Gene Expression.
She has a broad experience in teaching and research from 1994 to 2002 at different institutes like College for Applied Science for Women at Delhi University, Institute of Hotel Management, PUSA. She has also worked as a research associate at I.A.R.I, PUSA.
At JIIT, Dr. Wadhwa’s research focus is on purification of industrially important enzymes. She is Council of Scientific & Industrial Research (CSIR) NET qualified.
Value addition of biodegradable waste
Our research group is focussed in developing processes for converting the Waste material of food processing industry into valuable products..These waste materials contain principally biodegradable organic matter and disposal of them creates serious environmental problems. Waste materials can be reduced significantly through the use of new or modified processing methods and through reuse other into food ingredients, and valuable bio products .
The work “Exploiting Amorphophallus paeoniifolius: An underutilized aroid of India” is an attempt to increase the utilization and consumption of aroids, raising awareness to the importance of aroids which would in-turn ensure food and nutritional security.In this project a Wheat-Jimikand composite bread can be given to the pregnant women since the bread was rich in Dietary fiber content (2.49 g/100g) and Calcium (1158.42 mg/100gm).Development of bread from this underutilized tuber crop will add value to this crop.
Waste extracts of corm and peel of Amorphophallus paeoniifolius, can be used in “Bioprocessing of Cotton Fibre” The treated fibres showed weight loss and increased water absorption potential. Scanning Electron Microscopy (SEM), revealed partial degradation of cotton fibre, indicating its application of the extract in scouring of cotton fibre.
Feathers a waste by product of Poultry processing plant. can be degraded completely by Novel keratinase producing bacteria isolated from soil . When grown on chromogenic differentiation agar Hicrome bacillus agar from Himedia M1651 B. megaterium SN1 (appear asYellowish green colonies), B. thuringenesis SN2 (as Blue colonies), B. Pumilis SN3 (as Green colonies). These microbes could completely degrade pigeon and chick feathers to proteinaceous slurry within 5 days of incubation. This slurry can find application in animal feed production.
Study role of enzymes in the remediation of polluted environments
Non-biodegradable/toxic compounds are difficult to treat with biological treatment procedures alone. These contaminants are non-biodegradable and have been linked to cancer, mutagenesis, and long-term toxicity. Enzymes have a lot of potential for transforming and detoxifying harmful chemicals since they do so at a detectable rate. Hydrolases, dehalo-genases, transferases, and oxidoreductases are the most representative enzyme classes in the rehabilitation of polluted environments
