- JYOTHISHREE V “Let food be thy medicine and medicine be thy food” -Hippocrates Food waste is a significant global problem that impacts both developed and developing nations. According to UN estimates, roughly 1.3 billion tons, or one-third of the food produced globally, is lost or wasted each year. This not only worsens global food insecurity and hunger but also has detrimental effects on the economy, environment, and both. To summarize, food waste is a major global issue that requires immediate attention. It does, however, provide an opportunity to develop valuable biobased products that can benefit society and the environment. We can reduce greenhouse gas emissions, create renewable energy sources, improve soil health, and reduce waste sent to landfills by converting food waste into biogas, fertilizers, animal feed, enzymes, and bioplastics. The conversion of food waste into bio-based products is a long-term solution to the food waste problem. Using food waste as a feedstock, we can create a variety of bioproducts that can replace products based on fossil fuels and lead to the development of a more sustainable and circular economy. Finally, by converting food waste into valuable biobased products, we can build a more sustainable food system and a more resilient future for future generations.

- JYOTHISHREE V Studies carried out so far: The use of Salmonella is among the most promising applications of bacteria in the treatment of cancer. Researchers have discovered that Salmonella can multiply and infiltrate deep into tumor tissues, killing cancer cells. Salmonella can also be created to produce and release anticancer medications at the location of the tumor, improving the effectiveness of the treatment. Another kind of bacteria called Clostridium, which can survive in environments with little oxygen, is used in the treatment of cancer. Clostridium novyi-NT (C. novyi-NT). This bacterium is anaerobic, meaning it can only survive in environments without oxygen, such as the core of solid tumors. C. novyi-NT has been shown to be effective at killing cancer cells in preclinical studies, it can selectively target cancer cells while sparing healthy cells because tumors are known to have low oxygen levels. Preclinical studies have shown encouraging results after scientists were able to engineer Clostridium to produce and release toxic enzymes that kill cancer cells. In conclusion, cancer therapies based on bacteria present a promising new direction in cancer therapy. They may be less harmful and more efficient than conventional treatments. Additionally, they provide a more focused method of treating cancer, which may lower the danger of harming healthy cells. Even though preclinical and clinical research on the use of bacteria to treat cancer is still in its early stages, the results of several of these studies have been encouraging. However, there are still some issues that need to be resolved, including ensuring the safety of bacteria-based therapies and improving their efficacy. |
