Characterization of an exopolysaccharide produced by sp. YU16-RN5 and its potential to alleviate cadmium induced cytotoxicity in vitro.

Natural biopolymers have gained remarkable attention for bioremediation particularly in heavy metal removal and oil degradation due to their non-toxic nature and lack of secondary pollution. The exopolysaccharides (EPS) produced by the bacteria have become an important class of biopolymers that are employed in bioremediation. The bacteria isolated from the rhizospheric soil have higher metal tolerance and their EPS are effective in biosorption of heavy metals.

Extraction and characterization of an exopolysaccharide from a marine bacterium.

The marine bacterial exopolysaccharides (EPS) have transfigured the biotech sector with their myriad applications and prospects. This work was carried out to characterize and analyze the functional and biochemical properties of an EPS (EPS-DR3A) produced by a marine bacterium, Pseudoalteromonas sp. YU16-DR3A.

Development of sustainable approaches for converting the organic waste to bioenergy.

Dependence on fossil fuels such as oil, coal and natural gas are on alarming increase, thereby causing such resources to be in a depletion mode and a novel sustainable approach for bioenergy production are in demand. Successful implementation of zero waste discharge policy is one such way to attain a sustainable development of bioenergy. Zero waste discharge can be induced only through the conversion of organic wastes into bioenergy.

Carbohydrate and protein based biopolymeric nanoparticles: Current status and biotechnological applications.

Wide sustainability and reusability of biomacromolecules such as carbohydrates and proteins-based biopolymers pave the way for providing maximal importance in the field of generating biopolymeric nanoparticles. As compared to synthetic nanomaterials, carbohydrate and protein based biopolymeric nanomaterials offer unique advantages that include antibacterial, biocompatible, immunogenicity, and biodegradable properties. Additionally, they have the significant property of more size distribution.

Zerumbone, a Cyclic Sesquiterpene from Zingiber zerumbet Induces Apoptosis, Cell Cycle Arrest, and Antimigratory Effects in SW480 Colorectal Cancer Cells.

Zerumbone isolated from the rhizomes of Zingiber zerumbet was investigated for the mechanisms by which it exhibits antiproliferative activity in colorectal cancer cells (SW480). The results indicated that the zerumbone suppressed cell growth and enhanced cell apoptosis. Exposure to zerumbone induced generation of reactive oxygen species, reduced the cellular antioxidant status, decreased mitochondrial membrane potential, and activated caspase 3, caspase 8, and caspase 9 (p < 0.
