Desa Tanak Beak Kec. Batukliang Utara merupakan salah satu sentra penghasil buah naga. ini memiliki Kebun Kelompok Wanita Tani (KWT). Pada waktu panen sempat dikunjungi gubernur NTB untuk raya Buah naga yang banyak di tempat wisata ini, dikonsumsi oleh pengunjung dan kulitnya tidak termanfaatkan serta cenderung sebagai limbah mengganggu sekitar. tahap sosialisasi hampir semua anggota KWT Dusun ...

The cellulose synthesizing terminal complex consisting of subunits A, B, C, and D in Acetobacter xylinum spans the outer and inner cell membranes to synthesize and extrude glucan chains, which are assembled into subelementary fibrils and further into a ribbon. We determined the structures of subunit D (AxCeSD/AxBcsD) with both N- and C-terminal His(6) tags, and in complex with cellopentaose. Th...

BACKGROUND Barrier materials as cellulose membranes are used for guided tissue repair. However, it is essential that the surrounding tissues accept the device. The present study histologically evaluated tissue reaction to a microbial cellulose membrane after subcutaneous implantation in mice. Furthermore, the interaction between mesenchymal stem cells and the biomaterial was studied in vitro to...

Nata de coco is a type of beverage component is a cellulose compound produced from coconut water through a process that involves microbial fermentation known as Acetobacter xylinum. To increase the economic value, shelf life, and the benefits of diversification do nata product of nata de coco wet a fiber-rich instant drink of nata de coco. This research used Completely Randomized Design (CRD) a...

A powerful replica molding methodology to transfer on-demand functional topographies to the surface of bacterial cellulose nanofiber textures is presented. With this method, termed guided assembly-based biolithography (GAB), a surface-structured polydimethylsiloxane (PDMS) mold is introduced at the gas-liquid interface of an Acetobacter xylinum culture. Upon bacterial fermentation, the generate...

We proposed in a previous paper a unique form of j3-glucan association, nematic ordered cellulose (NOC) that is molecularly ordered, yet non-crystalline. NOC has unique characteristics; in particular, its surface properties provide with a function of tracks or scaffolds for regulated movements and fiber-production or Acetobacter xylinum [Kondo et al. 2002. Proc. Natl. Acad. Sci. USA 99: 14008-1...

Cellulose and sugar from microalgae can be utilized for the production of biofuel ethanol. Increasing cellulose and sugar synthesis capacity is key for high yield production of this biofuel. To enhance cellulose production, we transferred acsAB, responsible for cellulose synthesis in bacterium Acetobacter xylinum, into the cyanobacterium, Anabaena sp. strain PCC7120, by conjugation. PCR confirm...

The action of cellulosomes from Clostridium thermocellum on model cellulose microfibrils from Acetobacter xylinum and cellulose microcrystals from Valonia ventricosa was investigated. The biodegradation of these substrates was followed by transmission electron microscopy, Fourier-transform IR spectroscopy and X-ray diffraction analysis, as a function of the extent of degradation. The cellulosom...
