Development of Electrochemical Oxidation Methods for Treatment of Organic Radioactive Wastes (Sponsored by BRNS, DAE) (Ongoing)
Organic wastes arise in different industries including nuclear industry. Incineration is a traditional method for volume reduction and management of organic wastes. With the growing environmental concerns associated with incineration process, more eco-friendly alternatives are emerging. One such is mediated electrochemical oxidation process. The present project aims to develop electrochemical process for management of waste organic ion exchange resins and organic solvents employed in nuclear industry. The process occurs in water medium at near ambient conditions of temperature and pressure and converts organic materials into carbon dioxide, water etc. The process has the potential to address the issue of hazardous organic solid and liquid wastes which are difficult to incinerate.
Addressing Drinking water Issues in Slums in Greater Mumbai and its mapping using GIS (Sponsored by NRDMS, DST) (Ongoing)
In urban India, people living in slums are facing drinking water problems. An adequate supply of safe drinking water is a basic human need. More than 60% of the Mumbai city lives in slum communities. The present project aims at mapping and monitoring of drinking water quality in selected slums in Greater Mumbai. Since water quality is spatially variable in nature, therefore GIS will be used for mapping and analysis. Areas of poor water quality will be identified. Suitable low cost water purification technologies will be recommended accordingly. Dissemination of knowledge on the need for better management of urban water resources involving stakeholders like government departments, research and educational institution, NGOs, and local people will be done.
Testing, Development and Awareness Generation of Water Purification Techniques in Municipal Schools, Sponsored by- Mumbai Metropolitan Region- Environment Improvement Society (Completed)
Being financial capital of India, Mumbai’s population is rising rapidly. This is causing stress on limited resources such as water, power and living space enormously. A substantial group of our population in Mumbai is poor or live below poverty line in slum areas. People residing in such areas get water from various sources such as open tanks and wells, tanker supplies and common tap water supplies which could be possibly contaminated with physical, chemical and microbial impurities. Navi Mumbai is a fast developing satellite city spread across a wide area covering planned townships as well as villages. There are several villages in Navi Mumbai where people had to depend on various water sources such as open tanks, wells, and common tap water supply and tanker water supplies. Water quality assessment and awareness generation on water purification techniques and water conservation aspects among the school children and villagers is very important so that they understand that such a vital resource needs to be preserved and protected. This project is conceived to analyze the physical, chemical and microbial contamination of drinking water at selected villages of Panvel (Raigad).
Production of biosurfactants from marine bacteria using cost effective media by fermentation. Sanctioned under the Department of Science and Technology (SEED)-WOS B -2011(Completed)
Biosurfactants or microbial surfactants are surface-active biomolecules that are produced by a variety of microorganisms. The reason for their popularity as high value microbial products is because of their specific action, low toxicity, higher biodegradability, effectiveness at extremes of temperature, pH, salinity, widespread applicability and their unique structures which provide new properties that classical surfactants(chemical) may lack. Poor yields, large capital investment, difficulties in product recovery, purification and finished product analysis kept biosurfactants back from chemical surfactants. The project aims to overcome these problems by using cost effective raw materials as media components for fermentation purpose.          
The societal aspect of the project deals with the potential use of biosurfactants for oil spill management in the marine environment wherein an eco-friendly technology in the form of biosurfactants will be made available to local people (coastal communities) and production of biosurfactants can be considered as an alternate livelihood method for these communities.
Optimization and Up Scaling of Fly Ash Utilization for Sustainable Production of Grapes and Onion. Sponsored by- Fly Ash Unit, Department of Science and Technology (Completed)
Disposal of fly ash is very difficult and at the same time it causes environmental pollution. Fly ash is a by product and has proved to be an economical soil amendment as well as have potential in crop productivity and soil fertility improvement due to the presence of many nutrients but is deficient in nitrogen and phosphorus. Excessive rains, humidity, temperature, pests and disease are critical factors of risk to the cultivation and productivity of onion and grapes. That needs proper cropping pattern with supplementation of organic material and N and P sources. In this study optimization and up scaling of  fly ash with organic, chemical (NPK) and microbial inoculants like Azotobacter and AM fungi will be done for the  enhancement of crop productivity, pest control, shelf life improvement of product and  soil fertility.
Evaluation of comparative performance of available technologies for removal of pathogenic organisms and turbidity from drinking water
Microbial activity and presence of objectionable turbidity constitute major sources of contamination of surface water bodies. A variety of pathogenic organisms find their way into drinking water sources causing frequent outbreak of water borne diseases. The susceptibility to disinfection varies from organism to organism and presence of turbidity often hinders their effective disinfection. This proposal attempts to take a systematic investigation of various available technologies such as chlorination, ozonation, solar disinfection (SODIS), disinfection cum sedimentation, use of copper pot, Ultraviolet irradiation, silver or iodine impregnated resin filters and ultrafiltration candles for their effectiveness in disinfection of potable waters contaminated with different microorganisms and turbidity loads.

Development of recombinant insulin like polypeptide –p from Memordica Charatia. Sponsored by- Indian Council of Medical Research (2003-2006)
Diabetes mellitus is associated with abnormally high levels of sugar (glucose) in the blood due either to lack of insulin production (type I diabetes) or the resistance of target tissues to insulin (type II diabetes). The conventional treatment modalities, including chemically synthesized drugs and insulin obtained from non-human sources have inherent limitations and undesirable side effects. This has instigated research in alternate forms of medicine. The fruit of Momordica charantia, also known as bitter gourd or karela, has been used extensively in traditional systems for treating diabetes. The blood sugar-lowering action of the fresh juice or unripe fruit has been established in animal experimental models as well as human clinical trials. Two independent reports have attributed hypoglycaemic activity to peptide components polypeptide-p and MC6, in the Momordica Charantia fruit. The study aimed at molecular characterization of the peptide with antidiabetic properties from M. charantia for understanding the mechanism of action. The peptide gene will be cloned and expressed in a yeast system.
