Question

Bioremediation of these substances can be performed by lignin-degrading laccases and a namesake class of heme peroxidases. Supramolecular examples of these substances include J-aggregates. Examples of these substances like Rhodamine 6G are used as the lasing medium of a type of tunable laser. Most industrial examples of these substances consist of an azo group linking two rings. BASF was founded to manufacture these substances using products extracted from coal tar after William Henry (*) Perkin accidentally synthesized one of these substances (-5[1])from aniline. These [emphasize] (10[1])soluble substances often have extensively conjugated pi systems, and are labeled with FD&C numbers in the food industry. For 10 points, the textile industry’s main wastewater pollutants are what substances exemplified by Allura Red 40 and indigo? (10[1])■END■
