Isolation of enzyme-producing microbial strains and their effects on the color and quality of tobacco stems.

ABSTRACT: China is one of the world's major tobacco producers, yielding more than 2.2 million tons of tobacco leaves annually, among which approximately 25-30% constitute by-products such as tobacco stems. Dark-colored stems are favored for their high contents of reducing and total sugars, porous structure, thermal stability, and rich aroma precursors; however, their limited availability constrains large-scale industrial utilization. In contrast, light-colored stems are frequently discarded because of inadequate natural aging, resulting in significant resource waste. To enhance stem utilization and improve cigarette quality, enzyme-producing strains were isolated from dark-colored stems (cellulase: C8, Z16; polyphenol oxidase: A59, Z1), and a synthetic microbial community (C8-Z1) was established to
