A fruity aroma-producing strain WG4 was isolated from a water sample collected from the Western Ghats, India. The 16S rRNA gene sequence analysis of strain WG4 indicated that Chryseobacterium indologenes, a member of the family 'Flavobacteriaceae' is the closest related species with a pair-wise sequence similarity of 98.6%. Strain WG4 produces a fruity aroma when grown on nutrient or trypticase soy agar plates. The fruity aroma is more when the strain WG4 is grown on agar plates compared to their growth in broth. The aromatic compounds produced by the strain WG4 were identified as ester compounds and were confirmed as ethyl-2-methylbutyrate and ethyl-3-methylbutyrate based on Gas Chromatography-Mass Spectrometry (GC-MS) analysis and using standard reference compounds. Even after repeated subcultures strain WG4 produced the same aroma in high intensity. Thus, strain WG4 could serve as a source for the production of these flavour compounds.
