Bacterial Celluloses (BC) are gaining importance in research and commerce due to numerous factors affecting the bacterial cellulose characteristics and application in different industries. The aim of the present study was to produce bacterial cellulose in different media using different cultivation vessels. Bacterial cellulose was produced by static cultivation of Glucanacetobacter xylinum ATCC 10245 in different culture media such as Brain Heart Agar, Luria Bertani Agar /Broth, Brain Heart Infusion, Hestrin-Schramm and medium no. 125. Cultivation of bacterium was conducted in various culture vessels with different surface area. The cellulose membrane was treated and purified with a 0.1 M NaOH solution at 90 degreesC for 30 min and dried by a freeze- drier at -40 degreesC to obtain BC. The prepared bacterial cellulose was characterized by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy and X-ray diffraction (XRD). The amount of produced BC was related directly to the surface area of culture vessels.
由于多种因素会影响细菌纤维素的特性及其在不同行业的应用,细菌纤维素(BC)在研究和商业领域正变得越来越重要。本研究的目的是使用不同的培养容器在不同培养基中生产细菌纤维素。通过在不同培养基(如脑心琼脂、LB琼脂/肉汤、脑心浸液、赫斯特林-施拉姆培养基和125号培养基)中静态培养木醋杆菌ATCC 10245来生产细菌纤维素。在具有不同表面积的各种培养容器中进行细菌培养。用0.1 M氢氧化钠溶液在90℃处理和纯化纤维素膜30分钟,然后在-40℃用冷冻干燥机干燥以获得细菌纤维素。通过扫描电子显微镜(SEM)、傅里叶变换红外(FT-IR)光谱和X射线衍射(XRD)对制备的细菌纤维素进行表征。所生产的细菌纤维素的量与培养容器的表面积直接相关。
