The present invention relates to a spheroplast protein y (Spy)-exogenous protein-secreting Salmonella strain, which possesses a Spy protein-coding gene and has the rpoE gene deleted. The recombinant Salmonella strain according to the present invention, while exhibiting attenuated virulence due to the Spy protein, can maintain structural stability when fused with exogenous proteins such as pathogenic viruses, therapeutic proteins, or antigenic epitopes, through the structure and chaperone functions of the Spy protein. Therefore, the present invention can serve as a live attenuated vaccine. Furthermore, the present invention can be used as a protein delivery vehicle, a drug delivery vehicle, and in antigen-antibody reaction-based techniques for applications in other areas of biotechnology.

PROCESS FOR PREPARATION OF NATURAL AND ORGANIC POTASSIUM SORBATE The present invention relates to the process for production of natural and organic potassium sorbate. The natural and organic potassium sorbate is produced through microbial fermentation of natural carbohydrate source obtained from organic raw material tuber crop cassava followed by downstream processing steps of filtration, carbon treatment, evaporation, centrifugation and spin flash drying. The fermentation was carried out utilizing the Lactobacillus delbrueckii NCIM 2365, Bacillus coagulans MTCC 3543 and Lactobacillus acidophilus NCIM 5705, which were modified by the way of strain improvement through media optimization, filtration, carbon treatment, evaporation and centrifugation, the pellet material received was further dried in spin flash dryer resulting in finished product in powder form as potassium sorbate with sorbic acid (70-72%), other organic acids (10%),bioavailable potash (12%) and moisture (<5%). The natural and organic potassium sorbate powder produced has antimicrobial activity and addition of 0.1 to 0.5 % of the said natural preservative in food preparation of different food products like cheese and paneer, pickles, meat products, beverages like wines, canned food items, storage food items and bakery preparations enhances the shelf life of the product. It kills variety of food pathogens viz. Listeria sp., Salmonella sp., and Shigella sp in breads, paneer and pickles and on crops as foliar an
