Structure of cell walls observed by TEM in standard cork (a) and yellow stain (b, c, d). As shown in a, the cell wall comprises four successive layers: the middle lamella (ML), the primary wall (PW), which is a very thin layer adjacent to the ML (not evident), the highly suberized secondary wall (SW), and the tertiary wall (TW). Plasmodesmata traversing the cell wall are indicated by arrows in a and b. As it can be observed in b, some cells in YS exhibit a disorganized and discontinuous ML (ML*), with the removal of SW and TW; in c, there is TW removal, disorganization, and partial degradation of SW (indicated by an arrow). In d, separation between ML and SW, along with disorganization and partial degradation of SW, is observed (indicated by arrows) in YS cells. Microbial structures adjacent to the cell wall are visible in c and d

Background
The main application of cork is the production of stoppers for wine bottles. Cork sometimes contains 2,4,6-trichloroanisole, a compound that, at a concentration of ng/L, produces an unpleasant musty odor that destroys the organoleptic properties of wine and results in enormous economic losses for wineries and cork industries. Cork can ex...
