Halophilic microorganisms produce several metabolites having potential application in biotechnology and industry. They also produce polyhydroxyalkanoates (PHA), which are suitable replacements for conventional plastics for packaging food and non-food materials due to their biocompatible and biodegradable properties. PHA produced by the native isolate of Halomonas venusta KT832796 using a minimal medium was made into a film. It was characterized using Fourier Transform Infrared (FTIR) spectroscopy, Nuclear Magnetic Resonance (NMR) spectroscopy, GC–MS, UTM (Mechanical strength), Differential Scanning Calorimetry (DSC) and X-ray diffraction (XRD) analysis. Based on FTIR, NMR and GC–MS analyses the polymer produced by Halomonas venusta KT832796 was found to be poly(3-hydroxybutyrate). The polymer had a tensile strength of 26 MPa and Young’s modulus of 3 GPa and the melting temperature Tm 173.59 °C, which are found to be similar to the standard PHB polymer and the crystalline state was revealed by XRD pattern. This PHB polymer can be used in food packaging systems and medical applications for drug delivery. This is the first communication on characterization of PHA produced by Halomonas venusta.

嗜盐微生物产生几种代谢物，在生物技术和工业中具有潜在的应用。他们还生产聚羟基链烷酸酯（PHA），由于它们具有生物相容性和可生物降解的特性，因此可以代替传统塑料包装食品和非食品材料。将由哈莫单氏菌（Halomonas venusta） KT832796的天然分离物使用基本培养基制成的PHA制成薄膜。使用傅里叶变换红外（FTIR）光谱，核磁共振（NMR）光谱，GC-MS，UTM（机械强度），差示扫描量热法（DSC）和X射线衍射（XRD）分析对其进行了表征。基于FTIR，NMR和GC-MS分析Halomonas venusta生产的聚合物发现KT832796为聚（3-羟基丁酸酯）。该聚合物的拉伸强度为26 MPa，杨氏模量为3 GPa，熔融温度Tm 173.59°C，与标准PHB聚合物相似，并通过XRD图谱显示了结晶态。这种PHB聚合物可用于食品包装系统和医疗应用中以进行药物输送。这是由Halomonas venusta产生的有关PHA表征的首次交流。
