Bu çalışmada, laktik asit esteri olan etil laktatın, çevre dostu proses olarak nitelendiren, membran biyoreaktör ile üretimi 303, 313 ve 323 K  sıcaklıkta, 1:1, 3:1, 6:1 etanol:laktik asit molar reaktan besleme oranı ile gerçekleştirilmiştir. Sıcaklığın ve molar besleme oranının reaksiyon dönüşümüne ve ayırma performansına etkisi incelenmiştir. Membranların karakterizasyonunda taramalı elektron mikroskopu (SEM) ve atomik güç mikroskopu (AFM) kullanılmıştır. Sistem performansını belirlemek amacıyla, reaksiyonlar aynı koşulda kesikli reaktörlerde de yapılmıştır.  Eş molar beslemede, 323 K sıcaklıkta, kesikli reaktör ile 0.26 laktik asit dönüşümü elde edilirken, önerilen çevreci sistem ile 0.62 dönüşüm değeri elde edilmiştir.
