[Preface for special issue on industrial bioprocess technique front (2015)].

Industrial bioprocess is one of the most important research fields supports the promoting of biological manufacturing industry in China, and guarantees the implementation of bioscience and biotechnology research results into the industrial applications. For improving the interconnection between academic researchers and industrial stuffs and pushing research achievement into industrial implementation, bioprocess modelling and control committee of Chinese Society for Microbiology organized two tandem conferences separately in 2012 and 2014 on the topic of "Industrial bioprocess technology", focusing mainly technique front of industrial bioprocess. A special session on industrial technique applications was hold to stimulate cooperation. The conference received many good submissions from academic and industrial sectors. This special issue is based on selected excellent papers from the submissions, together with free submissions. The special issue consists of reviews and original papers, mainly involving the aspects closely related to the bio-industrial sectors including, i) high yield strain constructing and high throughput screening; ii) optimization and modification of industrial enzymes, and iii) bioprocess modelling and high efficient scale-up method.
