Using platinum nanocatalyst, a two-member team at the IIT Madras has successfully converted petroleum waste-product toluene into benzoic acid. Benzoic acid is used as a food preservative (E210) and medicine for fungal/bacterial infection. Toluene is converted into benzoic acid through selective and controlled oxidation in the presence of a catalyst — binaphthyl-stabilised platinum nanoparticles (Pt-BNP). Generally, organic reactions are carried out using organic solvents, which makes it expensive and also generates toxic waste. So, the team led by G. Sekar used water as solvent to make it environment-friendly. Also, a green oxidant (70% aqueous tert-butyl hydroperoxide or TBHP) is used for converting toluene into benzoic acid. When toluene is oxidised, it gives four products. But, the team used catalyst that they developed and then only benzoic acid is produced. No alcohol, aldehyde or ester is produced. The yield of benzoic acid varied from 68-96% depending on whether the toluene used is electron-deficient or electron-rich.

Kandhamal Haldi, a variety of turmeric indigenous to southern Odisha, has finally got the Geographical indication (GI) tag from Intellectual Property India. The recognition coincided with the state’s Foundation Day (Utkal Divas). Odisha, on April 1 1936, was carved out as a separate state in the then British India on a linguistic identity.

Scientists at the Centre for Cellular & Molecular Biology (CCMB) have discovered a new enzyme ‘Murein Endopeptidase’ which helps in breaking cell walls of bacteria. This discovery offers a potential for a new drug delivery route to arrest the anti-bacterial resistance through existing antibiotic drugs. Hence, it opens up fresh ways to target microbes, leading to a new wave of antibiotic drugs. The man behind this discovery is Pavan Kumar Chodisetti, research student and his mentor Dr Manjula Reddy. Antibiotics are medicines used to prevent and treat bacterial infections. The findings have been published in the latest issue of Proceedings of National Academy of Sciences, USA
