title: A new method for rapid screening of ester-producing yeasts using in situ HS-SPME.
abstract: The selection of ester-producing yeasts is difficult because these molecules evaporate quickly, are extremely unstable and may be missed during analytical manipulation. We propose an easy, fast and efficient headspace-SPME method for screening of ester-producing yeasts directly at the extraction vials (in situ HS-SPME).
