查询词典 anisaldehyde

UV 254nm, 366nm and anisaldehyde as a chromogenic agent were used for detecting compounds of these strains. Results indicate that the metabolites of these strains were the most abundant when these strains were fermented in No.1 and No.4 media, and only few in No.2 and No.3. Metabolites of each strain were different in different media.
