Abstract

In this research, the effects of microorganisms on suede quality of double-face leather were examined. The bacterial numbers on salted sheepskin samples were found as 1.8x106-4.3x107 cfu/g on solid medium and 1.9x106-4.7x107 cfu/g on halophile medium containing 10-30% NaCI. However it was found that salted sheepskins contained 4.4x101-2.0x104 cfu/g of fungi. While 53-74% of halophilic bacteria and 39-58% of fungi showed proteolytic activity, 47-62% of halophilic bacteria and 35-54% of fungi showed lipolytic activity. It was observed that defective light stained areas on suede surface of finished double- face leathers were caused by microorganisms on salted sheepskins and that these defects correspond to 35% of the total double-face leathers amount. Consequently, it was decided that the proteolytic and lipolytic activities of microorganisms on the flesh side of the sheepskins decreased the suede quality and caused economical losses.

Özet

Bu araştırmada kürk-süetlerin süet kalitesi üzerine mikroorganizmaların etkisi incelenmiştir. Tuzla konservelenmiş koyun derisi örneklerinin bakteri sayısı katı ortamda 1.8x106-4.3x107 cfu/g olarak ve % 10-30 NaCI içeren halofil ortamda 1.9x106-4.7x107 cfu/g olarak bulunmuştur. Tuzlu koyun derilerinin 4.4x101-2.0x104 cfu/g sayıda fungus içerdiği belirlenmiştir. Halofilik bakterilerin % 53-74' ü ve fungusların %39-58' iproteolitik aktivite gösterirken, halofilik bakterilerin %47-62' si ve fungusların %35-54' ü lipolitik aktivite göstermiştir. Kürk-süetlerin süet tarafındaki açık renkli kusurlu kısımların mikroorganizmalardan kaynaklandığı ve toplam kürk-süetlerin % 35' inde bu kusurların bulunduğu gözlemlenmiştir. Sonuç olarak; koyun derilerinin et kısımlarındaki mikroorganizmaların proteolitik ve lipolitik aktivitelerinin süet kalitesini düşürdüğü ve bunun ekonomik kayıplara neden olduğu ortaya konulmuştur
