DOWN STREAM PROCESSING

Sanjeet Kumar Ravenshaw University sanjeet.biotech@gmail.com ·          Downstream processing refers to the recovery and purification of biosynthetic products. The extraction and purification of a biotechnological product from fermentation is referred to as downstream processing (DSP) or product recovery. ·          DSP is as complex and important as fermentation process. ·          The methodology adopted for downstream processing depends on the nature of the end product, its concentration, stability and the degree of purification required, besides on the presence of other products. ·          The desired products for isolation by DSP are most frequently metabolites which may be present as follows:- 1.       Intracellular metabolites- Vitamins 2.       Extracellular metabolites- amino acids 3.       Both Intra- and Extra- cellular- Flavomycin Stages in Downstream processing Downstream processing of metabolites is a multistage operation and broadly divided in

A Review on Pharmacological aspects of Amorphophallus species

A. Behera & Sanjeet sanjeet.biotech@gmail.com Introduction Millions of people in many developing countries do not get enough food to meet their daily requirement and many more suffer deficiency of micronutrients. The rural and tribal communities even today depend on wild resources including wild edible tuber(s) to meet their daily food requirement and more particularly during the period of food crisis. The value of wild edible plants in food security has not been given sufficient attention in India and particularly in Odisha. During last few years some attempt has been made to document the rich indigenous knowledge on the medicinal use of wild plants but socio-economic, traditional nutritional aspect of wild food plants still lack adequate attention. There are about 1532 edible wild food species available in India mostly in Eastern Ghats, Western Ghats and Himalayan Hill ranges (Reddy et al ., 2007). Tubers play a major role in supplementing staples foods with micronutrients

This is abstract of  accepted article , going to publish in National Institute of Technology Sanjeet Kumar 1 , Shakti Kant Rath 2 and Padan Kumar Jena 1 1.         Department of Botany, Ravenshaw University, Cuttack-75 3003, Odisha 2.         School of Life Sciences, Ravenshaw University, Cuttack-75 3003, Odisha Simlipal Biosphere Reserve (SBR) forest is located in the district Mayurbhanj of the state, Odisha.It has a mixed type of vegetation such as semi-evergreen, tropical moist broadleaf and tropical moist deciduous forest. It is the hub of different tribal communities such as Mankardia, Kharia, Kolho, Santhal, Munda etc. They do agriculture for short periods and depend on wild plants for their food and medicine. Among their wild foods Dioscorea bulbifera (Pita Aalu) is important as per availability and consumption rate. The details of the plant in terms of ethnobotanical values, diversity at SBR and its use in maintaining health care has been documented through fiel
