AI Summary & Key Takeaways
AI InsightIt was found that S. typhimuriu 60-62 was inhibited more than was E. coli K12 107, and the most effective Lactobacillus strains were L. fermentum KY2002 and L. plantarum KY2402.

Abstract
Total number of 36 Lactobacillus strains were isolated and identified from cecum in our previous study. Some properties of those strains were determined. These properties were lactic acid production, proteolytic activity and antibacterial activity against pathogens. It was determined that lactic acid productions ranged from 2.200 to 6.800 mg/ml, and proteolytic activity ranged between 0.013 and 8.600 mg tyrosine/5 ml. Strains with high proteolytic activity produced less lactic acid than the others. Beyond that 25 strains inhibited E. coli K12 107 and S. typhimurium 60-62 at different levels. It was found that S. typhimuriu 60-62 was inhibited more than was E. coli K12 107, and the most effective Lactobacillus strains were L. fermentum KY2002 and L. plantarum KY2402.
Özet
Daha önceki çalışmalarımızda körbarsaktan izole edilen ve tanımlanan 36 adet Lactobacillius suşunun laktik asit üretimleri, proteolitik aktiviteleri ve patojenlere karşı antibakteriyel aktiviteleri incelenmiştir. Suşların laktik asit üretimlerinin 2.200-6.800 mg/ml ve proteolitik aktivitelerinin 0.013-8.600 mg tyrosine/5 ml arasında değiştiği belirlenmiştir. Proteolitik aktivitesi yüksek suşlar diğer suşlara nazaran daha az laktik asit üretmiştir. Suşlardan 25'i ise E.coli K12 107 ve S. typhimurium 60-62'yi değişik düzeylerde inhibe etmiştir. S. trypimurium 60-62'nin E.coli K12 107'ye göre daha fazla inhibe edildiği, en etkili suşların L. fermentum Ky2002 ve L. plantarum Ky2402 olduğu saptanmıştır.
