Deskripsi
The <i>Streptomyces</i> produce a great diversity of specialized metabolites, including highly volatile compounds with potential biological activities. Volatile organic compounds (VOCs) produced by nine <i>Streptomyces</i> spp., some of which are of industrial importance, were collected and identified using gas chromatography–mass spectrometry (GC-MS). Biosynthetic gene clusters (BGCs) present in the genomes of the respective <i>Streptomyces</i> spp. were also predicted to match them with the VOCs detected. Overall, 33 specific VOCs were identified, of which the production of 16 has not been previously reported in the <i>Streptomyces</i>. Among chemical classes, the most abundant VOCs were terpenes, which is consistent with predicted biosynthetic capabilities. In addition, 27 of the identified VOCs were plant-associated, demonstrating that some <i>Streptomyces</i> spp. can also produce such molecules. It is possible that some of the VOCs detected in the current study have roles in the interaction of <i>Streptomyces</i> with plants and other higher organisms, which might provide opportunities for their application in agriculture or industry.
