Ezine cheese is a non-starter and long-ripened cheese produced in the Mount of Ida region of Canakkale, Turkey, with a protected designation of origin status. Non-starter lactic acid bacteria (NSLAB) have a substantial effect on the quality and final sensorial characteristics of long-ripened cheeses. The dominance of NSLAB can be attributed to their high tolerance to the hostile environment in cheese during ripening relative to many other microbial groups and to its ability to inhibit undesired microorganisms. These qualities promote the microbiological stability of long-ripened cheeses. In this study, 144 samples were collected from three dairies during the ripening period of Ezine cheese. Physicochemical composition and NSLAB identification analyses were performed using both conventional and molecular methods. According to the results of a 16S rRNA gene sequence analysis, 13 different species belonging to seven genera were identified. Enterococcus faecium (38.42%) and E. faecalis (18.94%) were dominant species during the cheese manufacturing process, surviving 12 months of ripening together with Lactobacillus paracasei (13.68%) and Lb. plantarum (11.05%). The results indicate that NSLAB contributes to the microbiological stability of Ezine cheese over 12 months of ripening. The isolation of NSLAB with antimicrobial activity, potential bacteriocin producers, yielded defined collections of natural NSLAB isolates from Ezine cheese that can be used to generate specific starter cultures for the production of Ezine cheese (PDO).

Various countries established Geographical Indication (GI) system to protect the right and traditionality of their native products. The regulations vary by country but can be divided accordingly: Protection by trademark systems such as in USA, Special Protection for Geographical Indication as in EU, Protection by both schemes as in China and Korea. Within the systems, countries provide diverse schemes such as PDO and PGI in EU depending on the scope of the product. However, GI system in Korea provides one definition which only protects products that express definite tie to its territory of origin, preliminary with the origin of the ingredient. It is necessary for the government and industry to seek ways to revitalize the local economy in the global market and increase the number of GI products by aligning GI systems with foreign countries and support mutual bilateral agreement.

Acetic acid bacteria (AAB) are versatile organisms involved in the production of variety of fermented foods, such as vinegar and kombucha, and products of biotechnological relevance, such as bacterial cellulose. In the present study, Malatya apricot, a variety with protected designation of origin (PDO), and vinegar samples produced using various fruits were used to isolate AAB. The 19 AAB isolates obtained were typed using (GTG)5 fingerprinting, and the ones selected were identified by sequencing either 16S rDNA alone or in combination with 16S-23S rRNA internal transcribed spacer region or ligA gene. While all apricot isolates (n = 10) were Gluconobacter cerinus, vinegar isolates (n = 9) were composed of Komagataeibacter saccharivorans, Acetobacter syzygii, and possible two new species of AAB, Komagataeibacter sp., and Gluconobacter sp. (GTG)5 fingerprinting showed the presence of several genotypes of G. cerinus in the apricot samples. Screening for some technologically relevant properties, including thermotolerance, ethanol tolerance, and cellulose production capability, showed that all Komagataeibacter and some Gluconobacter isolates could tolerate the temperature of 35℃, and that vinegar isolates could tolerate up to 8% ethanol. One isolate, Komagataeibacter sp. GUS3 produced bacterial cellulose (1 g/l) and has the potential to be used for cellulose production.

This study reviews the concept and protection system for the geographical Indication(GI) to support the Korea-EU FTA. A geographical indication(GI) is a name or sign used on certain products or which corresponds to a specific geographical indication or origin (eg. a town, region, or country). The use of a GI may act as a certification that the product possesses certain qualities, or enjoys a certain reputation, due to its geographical origin. In the WTO Agreement on Trade-Related Aspects of Intellectual property Rights("TRIPS"). There are, in effect, two basic obligations from Article 22 to article 23 on WTO member governments relating to GIs in the TRIPS agreement. Geographical Indications have long been associated with Europe as an entity, where there is a tradition of associating certain food products with particular regions, Under European Union Law, the protected designation of origin system which came into effect in 1992 and 2003 regulates the following geographical indications: Protected designation of origin(PDO) and protected geographical indication(PGI) and Traditional Specialty Guaranteed(TSG). They have 5,000 articles for GI. We have the GI system and 40 articles rotating to registration by the law for quality management of production in agriculture. Cinclusinally, geographical indications could potentially serve as tools to helf holders of trade benefit more equitable through the mutual Acceptance for Korea-EU FTA.
