Abstract

Coliform bacteria were isolated and identified from 24 butter samples which are sold in Erzurum. Total 187 coliform strains, which have been identified, consisted of 41 Escherichia coli type II (21.9%), 32 Klebsiella spp. (17.1%), 27 E. coli type I (14.4%), 22 Enterobacter aerogenes (11.8%), 18 K. pneumoniae (9.6%), 12 Ent. cloceae (6.4%), 12 Ent. Agglomerans (6.4%), 8 Citrobacter freundii (4.3%) and 6 C. divercus (3.2%). Nineteen of strains (4.8%) couldn’t be identified. Identification of coliform bacteria was based on İNVİC tests. These tests, however, have been insufficient because these species of bacteria have contained a large number of transition types. For this reason, the other characteristics giving strict results have been used in identification. Lysinedecarboxylase, H2S, and motility tests have been considered as supplementary test in identification.

Abstract

Bu araştırmada, Erzurum piyasasında kahvaltılık olarak satılan tereyağlarından koliform grubu bakteriler izole edilmiş ve tanımlanmasına çalışılmıştır. Yirmidört örnekten izole edilen 187 adet koliform suşundan 41’i (%21.9) Escherichia coli Tip II, 32’si (%17.1) Klebsiella spp, 27’si (%14.4) E. coli Tip I 22’si (%11.8) Enterobacter aerogenes, 18’i (%9.6) K. pneumoniae, 12’si (%6.4) Ent. cloceae, 12’si (%6.4) ,Ent. Agglomerans, 8’i (%4.3) Citrobacter freundii ve 6’sı da (%3.2) C. divercus olarak identifiye edilmiştir. Dokuz suş ise (%4.8) tanımlanamamıştır.
