Rashmi Saraswat, Vijeshwar Verma, Srinivas Sistla, Indu Bhushan

Background: Lipases are used in detergent industries to minimise the use of phosphate-based chemicals in detergent formulations. The use of lipase in household laundry reduces environmental pollution and enhances the ability of detergent to remove tough o... see more

Lining Tang, Kai Huang, Jun Xie, Dan Yu, Lei Sun, Qing Huang, Yanjun Bi

Background: Juvenile Yoshitomi tilapia is often infected by pathogens and results in low-level survival rate. Bacillus subtilis, as a probiotic, may have beneficial effects on Y. tilapia with compound 1-deoxynojirimycin (DNJ), which has antibacterial acti... see more

Demao Li, Ke Zhang, Limei Chen, Mengxun Ding, Minli Zhao, Shulin Chen

Background: Mutation breeding is one of the most important routes to achieving high docosahexaenoic acid (DHA) productivity using Schizochytrium. However, few selection strategies have been reported that aim to generate a high DHA content in Schizochytriu... see more

Pags. 58 - 63  

Chiu-Shyan Soo, Wai-Sum Yap, Wei-Min Hon, Norhayati Ramli, Umi Kalsom Md Shah, Lai-Yee Phang

Background: The development of a potential single culture that can co-produce hydrogen and ethanol is beneficial for industrial application. Strain improvement via molecular approach was proposed on hydrogen and ethanol co-producing bacterium, Escherichia... see more

Hedan Li, Chengwei Hao, Daqing Xu

Background: Escherichia coli has been widely used as a host to clone and express heterologous genes. However, there are few vectors available for cloning and expressing extremely toxic genes, which limits further basic and applied research on extremely to... see more

Pags. 88 - 94  

Leonidas Matsakas, Maria Giannakou, Dimitrij Vörös

Background: Dependence on fossil resources, for the production of fuels and energy, has resulted in environmental and financial problems, which require our immediate action in order to reverse the situation. Use of renewable sources for the production of ... see more

Xianbo Jia, Xinjian Lin, Chenqiang Lin, Lirong Lin, Jichen Chen

Background: Catalase (CAT) is an important enzyme that degrades H2O2 into H2O and O2. To obtain an efficient catalase, in this study, a new strain of high catalase-producing Serratia marcescens, named FZSF01, was screened and its catalase was purified and... see more

Pags. 110 - 117  

Yan Wu, Tao Li, Qinghua Cao, Xuedan Li, Yizheng Zhang, Xuemei Tan

Background: Zymomonas mobilis is a Gram-negative microaerophilic bacterium with excellent ethanol-producing capabilities. The RecET recombination system provides an efficient tool for direct targeting of genes in the bacterial chromosome by PCR fragments.... see more
