Thirty-four Acetobacter strains, representing Acetobacter aceti, Acetobacter pasteurianus, Acetobacter pomorum, Acetobacter peroxydans, Acetobacter lovaniensis, Acetobacter estunensis, Acetobacter orleanensis, Acetobacter indonesiensis and Acetobacter tropicalis, were subjected to a polyphasic study that included DNA-DNA hybridizations, DNA base ratio determinations, 16S rDNA sequence analysis ...

Nata is a bacterial cellulose obtained from the fermentation of Acetobacter xylinum. It often found in desserts as health supplement because its high fiber content. not only produced coconut water, known nata-de-coco but can also be other sources, such wastewater rice washing, called nata-de-leri. This study aimed to optimize parameters (nata-de-leri) by statistical methods improve production. ...

Kulit kopi yang dikeringkan (cascara) dapat dimanfaatkan menjadi minuman seduhan layaknya teh. Pengembangan cascara sebagai fermentasi (kombucha) banyak dilakukan. Kombucha merupakan larutan dan gula ditambahkan starter kombucha yaitu simbiosis bakteri Acetobacter xylinum beberapa jenis khamir diantaranya Saccharomyces cerevisiae. Penelitian bertujuan mengetahui karakteristik kimia (total asam,...

Kulit pisang kepok merupakan hasil samping pengolahan yang jenis sering digunakan sebagai bahan baku olahan pisang, dan bernilai ekonomis rendah. dapat dimaanfaatkan media pertumbuhan Acetobacter xylinum untuk menghasilkan selu-losa bakterial. Penelitian ini bertujuan mengetahui pengaruh penambahan gula lama fermentasi terhadap karakteristik selulosa bakterial dihasilkan, serta penghasilan komb...

Jackfruit straw and purple cabbage are ingredients that can replace coconut water as a substrate in making nata because they contain nutrients be used for the growth of Acetobacter xylinum bacteria. The aim this research was to determine characteristics produce highest antioxidant activity. experimental design is Completely Randomized Design with two factors. first factor ratio jackfruit water,...

The synthesis of cellulose by washed suspensions of Acetobatter xylinum proceeds in the presence of iodoacetate at concentrations which completely inhibit the oxidation of glyceraldehyde-a-phosphate (1). Since glucose was the only carbon compound added, the possibility was considered that the energy required for the biosynthetic process may be derived from reactions linked to the pentose phosph...
