Penelitian ini bertujuan untuk menganalisis pengaruh perbedaan konsentrasi Acetobacter Xylinum terhadap kualitas Nata de Banana dari limbah kulit buah pisang raja. Peneliti menggunakan sebagai objek penelitian karena terdapat senyawa pendukung pertumbuhan (growth promoting factor) dan adanya kandungan karbohidrat yang akan meningkatkan mikroba. Jenis digunakan yaitu Eksperimen dengan pendekatan...

A second cellulose synthase gene (acsAII) coding for a 175-kDa polypeptide that is similar in size and sequence to the acsAB gene product has been identified in Acetobacter xylinum AY201. Evidence for the presence of this gene was obtained during analysis of A. xylinum mutants in which the acsAB gene was disrupted (I.M. Saxena, K. Kudlicka, K. Okuda, and R.M. Brown, Jr., J. Bacteriol. 176:5735-...

Acetobacter xylinum strains are known as very efficient producers of bacterial cellulose which, due to its unique properties, has great application potential. One of the most important problems faced during cellulose synthesis by these bacteria is generation of cellulose non-producing cells, which can appear under submerged culture conditions. The reasons of this remain unknown. These studies h...

Bacterial cellulose (BC) producing bacterial strains were isolated from bio-extract (BE). Nine isolates that can produce BC in Hestrin–Schramm medium (HS medium) identified. The production of these was then investigated using agricultural waste as a raw material. (banana, papaya, dragon fruit, and mango peels) used carbon source for production. After incubation, the highest dry weight reached 0...
