Optimization Of process parameters for microbial cellulose production from rice-washing wastewater (NATA-DE-LERI) By Acetobacter Xylinum

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. First, Placket-Burman Screening Design was applied address essential parameter components affecting nata-de-leri Eight factors are continuously checked, and unimportant elements removed obtain smaller, more manageable set characteristics. Second, feedback surface method using Central Composite (CCD) used determine optimal level yield response. The results this show that sucrose concentration, CO(NH2)2 inoculum concentration time believed main for nata estimated values production when 500 ml rince washing follows: 17.5 g; 12 volume starter 60 ml; days. 97.20%. From study, optimum 20% larger than baseline
