A biotransformaDon reacDon is a chemical conversion of a substance into a desired product with the aid of whole, living cells containing the necessary enzymes. In addiDons to living cells, other substances, such as vegetable strips, will also catalyze biotransformaDon reacDons. Advantages of biotransformaDon reacDons include the following: the ability to recycle material, the use of less hazardous chemicals, the ability to compost vegetable strips, the use of inexpensive materials that are locally available, and the ability to produce a single isomer. The biotransformaDon reacDon for the conversion of benzofuranyl methyl ketone (BMK) to (-)-benzofuranylethanol (BMA) using carrot strips as …

Here we report the sensing properties of the aqueous solution of mesotetra(N-methyl-4-pyridyl)porphine tetrachloride (1) for simultaneous detection of toxic metal ions by using UV-vis spectroscopy. Cationic porphyrin 1 displayed different electronic absorptions in UV-vis region upon interacting with Hg2+, Pb2+, Cd2+, and Cu2+ ions in neutral water solution at room temperature. Quite interestingly, the porphyrin 1 showed that it can function as a single optical chemical sensor and/ or metal ion receptor capable of detecting two or more toxic metal ions, particularly, Hg2+, Pb2+, and Cd2+ ions coexisting in a water sample. Porphyrin 1 in an aqueous solution provides a …
