Composition and Significance of Bacterial Microbiota and Volatile Organic Compounds of Swiss-Dutch-Type Cheese as Determined by PCR-DGGE and HS-GC

This study aimed to determine seasonal differences in the composition of bacterial microbiota and volatile organic compounds (VOCs) in Swiss-Dutch-type cheese (manufactured between 2012 and 2014). Bacterial diversity and VOCs (acetaldehyde; ketones: acetone, diacetyl, acetoin; alcohols: methanol, ethanol; esters: ethyl acetate, ethyl propionate, ethyl butyrate; fatty acids: acetic acid, propionic acid, isobutyric acid, butyric acid, isovaleric acid, valeric acid, isocaproic acid, caproic acid, heptanoic acid) were determined by polymerase chain reaction - denaturing gradient gel electrophoresi...
