Özet
Bu çalışmada üç adet konjuge linoleik asit (KLA) üreten Lactobacillus suşu 2000 µg/ml linoleik asit (LA) ve çeşitli konsantrasyonlarda Tween 80 ilave edilmiş rekonstitüe yağsız süt tozu (%10) içinde 36 saate kadar kültüre edilmiştir. İnkübasyon boyunca kültür süpernatantlarında toplam KLA düzeyleri UV-spektrofotometre ile tespit edilmiştir. KLA düzeyleri 5 ve 20 mg/ml Tween 80 ilavesi ile önemli (P0.05) seviyede artmıştır. Bununla birlikte, Tween 80 konsantrasyonunun 20 mg/ml'den 40 mg/ml'ye arttırılması KLA düzeyinde bir artışa neden olmamıştır. İnkübasyon esnasında Lactobacillus suşlarının gelişme hızı ve KLA üretimlerinde benzer artış oranları gözlenmiştir.
In this study, three conjugated linoleic acid (CLA)-producing strains of Lactobacillus were cultured up to 36 in reconstituted skim milk powder (10%) supplemented with 2000 µg/ml of free linoleic acid (LA) and various concentrations of Tween 80. During the incubation, total CLA levels in the culture supernatants were determined by UV-spectrophotometry. The CLA levels significantly (P>0.05) increased with the addition of 5 and 20 mg/ml Tween 80. However, increasing Tween 80 concentration from 20 to 40 mg/ml did not appear to enhance CLA levels. Similar increase patterns were observed in the growth rate and CLA production of Lactobacillus strains during the incubation.
