"Enriched oil energy microalgae cultivation and biodiesel preparation technology" through scientific and technological achievements

Recently, the “Enriched Oil Energy Microalgae Cultivation and Biodiesel Preparation Technology” jointly completed by the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Shenyang Research Institute of Chemical Industry Co., Ltd., and Tsinghua University has passed the organization organized by China Petroleum and Chemical Industry Federation in Beijing. Identification of scientific and technological achievements.

The appraisal committee chaired by the researcher Lei Tingzhou seriously listened to the scientific and technological achievements research report and reviewed the test report, the new report and other relevant supporting materials. They all agreed that the research results have reached the leading domestic level, in which the Dalian Institute of Chemicals is responsible for the improved species. The efficient mutagenesis screening technology and the lipase-phospholipase preparation biodiesel process undertaken by Tsinghua University have reached the international advanced level.

Under the leadership of the researcher Xue Song, the Dept. of Marine Biological Engineering of the Dalian Institute of Chemical Research focused on the key technical problems in the research and application development of energy microalgae. In view of the long time and low efficiency of selection of excellent algae species, using chlorophyll fluorescence kinetic parameters as indicators, the optimization of microalgae room temperature plasma mutagenesis conditions, the direct transesterification of microalgae biomass characterization, and the combination of characteristic fatty acids were established. A variety of assessment methods have been developed to establish effective screening techniques and procedures for improved varieties, and a highly efficient culture process for microalgae photobioreactors has been established. Under the pilot scale, direct sunlight has been used to achieve continuous stable growth with a growth rate of 20 gm-2day-1. In response to the current lack of a unified method in the evaluation of microalgae biomass, we actively promoted the standardization process, drafted and obtained the promulgation and implementation of China's first marine microalgae biomass determination series of local standards, and focused on the characteristics of microalgal light energy utilization. The parameter microalgae photoautotrophic culture integrated measurement and control system is used to achieve the coupling adjustment between environmental parameters and growth. The above work laid a technical foundation for practical applications such as the stable industrial production of energy microalgae and the production of high value natural products of microalgae.
