Dr. Yiqing Yao received his PhD in bioenergy from Key Laboratory of Cell Activities and Stress Adaptations, Ministry of Education, Lanzhou University, China. His PhD research was mainly focused on converting biomass to biofuels by anaerobic fermentation (liquid-state and solid-state), analysis of intermediate metabolite, pretreatment of lignocellulosic materials and analysis of the structure and component of lignocellulose.He is currently research associate in the Department of Biological Systems Engineering, Washington State University.

He has published the relevant works in Biotechnology for Biofuels, Bioresource Technology and Energy. Because of the particular topic of the paper published in Biotechnology for Biofuels, LAP Lambert Academic Publishing invited him to publish this work in the form of a book (in an expanded version of my research-work). To date, he has received three invitations from the international conferences as an oral speaker due to the excellent work published in Biotechnology for Biofuels, such as Industrial Biotechnology Congress (Aug 10-12, 2015| Birmingham, UK), Word Congress on Applied Microbiology (Aug 18-20, 2015| Frankfurt, Germany) and Green Energy Conference and Expo-2015 (Sep 21-23, 2015| Orlando, Florida USA). In addition, he has applied for an invention patent (A method of process optimization of liquid-state anaerobic digestion of poplar processing residues for methane production) and an utility patent (A device used for isolating anaerobic bacteria), both of which have been authorized by State Intellectual Property Office of the P.R.C. The later patent is used for the isolation of anaerobic microbial, such as methanogens, from environmental samples. Based on the above works, he won Zhengdao Li Academic Award, China (Who won the Noble Prize for physics), National Scholarship, Ministry of Education, China and HaoranJian Environmental Microbiology Excellence Paper Award, China.

Under anaerobic environment, the relationship between the population dynamics and operating conditions, especially the pattern of response of the community to the design and operating conditions.

Polishing effluent from anaerobic fermentation for water use. The processes are mainly physical processes for fine solids removal, chemical processes for disinfection and biological processes for further reduction in nutrients.

Ammonia-recycling technology for reducing the inhibition of ammonia on anaerobic microbial. This involves testing the major operational parameters such a mass flow ratio, temperature, pressure, and resident time.

Compare different pretreatments of several different cellulosic biomass materials for their effectiveness in producing bioproducts by anaerobic digestion, determine the optimal conditions for pretreatment, enzymatic hydrolysis and fermentation and do a preliminary economic analysis of the most promising process conditions.
