These bacteria are often called probiotics because can confer a positive impact on the human body. Each species of lactic acid bacteria has a different probiotic effect that requires selection and identification to obtain a good probiotic strain. The identification of lactic acid bacteria in this study used a method of molecular identification with a marker gene of 16S rRNA. Lactic acid bacteria from red cabbage fermentation have a 100% similarity to Weissella cibaria and Weissella confusa. Phylogenetic analysis showed a relationship between lactic acid bacteria isolates from red cabbage fermentation with bacteria from the other Weissella genus.Keywords: lactic acid bacteria, fermentation, 16S rRNA, probiotics","PeriodicalId":113222,"journal":{"name":"JURNAL BIOS LOGOS","volume":"352 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115977417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pengidentifikasian akan keberadaan jenis-jenis tumbuhan paku air (Azolla sp.) penting untuk dilakukan guna mendukung upaya pengembangan, pembudidayaan dan eksplorasi tumbuhan Azolla sp. Penelitian ini bertujuan untuk mengidentifikasi spesies tumbuhan paku air (Azolla sp.) secara morfologi dan molekuler dengan menggunakan gen rbcL. Hasil penelitian menunjukkan bahwa berdasarkan karakter morfologi sampel tumbuhan Azolla sp. asal Tondano Sulawesi Utara menunjukkan kemiripan dengan spesies A. pinnata dan Azolla asal Magelang Jawa Tengah menunjukkan kemiripan dengan spesies A. microphylla. Identifikasi menggunakan sekuens gen rbcL menunjukkan bahwa sekuens sampel tumbuhan Azolla asal Tondano (WM1) memiliki tingkat kemiripan 100% dengan A. pinnata dan Azolla asal Magelang (WM2) memiliki tingkat kemiripan 100% dengan A. microphylla yang terdapat dalam GenBank.

Identification of water ferns (Azolla sp.) is important to be carried out to support the development, cultivation, and exploration of Azolla sp. This study aimed to identify species of aquatic plants (Azolla sp.) morphologically and molecularly using the gene rbcL. The results demonstrated that based on the morphological characters, the Azolla sp. from Tondano, North Sulawesi, showed similarity with species A. pinnata and Azolla from Magelang, Central Java, showed similarity to species A. microphylla. Identification using rbcL gene sequences showed that the sample sequence of plants Azolla from Tondano (WM1) had a 100% similarity level with A. pinnata and Azolla from Magelang (WM2) had a 100% similarity level with A. microphylla available in GenBank. Genetic distance analysis showed that both WM1 and WM2 samples had a close relationship with the genetic distance value of 0.060.Key words: Azolla sp., morphological identification, molecular identification, rbcL gene","PeriodicalId":113222,"journal":{"name":"JURNAL BIOS LOGOS","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133949391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
