Scientific research and innovation of microbial engineering and technology research team of Shaanxi Normal University Early spring scientific research is busy

Early spring people are more diligent, and it is time to forge ahead.
“After the Lantern Festival on the 15th day of the first month, our team will go to the oil production area of the northern Shaanxi oilfield, the Hongjiannao Lake area and the saline-alkali land treatment demonstration project pilot area to observe and sample again, and the team member Huang Minggang has gone to the oilfield site on the tenth day of the first month, and Yu Feng, Guo Yanzhao, Qi Fei and other young R&D personnel have also devoted themselves to the work of preparing experiments, conducting experiments or preparing reports, declaring ‘Qin Chuangyuan’, preparing provincial and municipal department projects or cooperating with relevant science and technology enterprises on the seventh day of the first lunar month of the following year.” Professor Chen Wuling, the leader of the microbial engineering and technology research team of Shaanxi Normal University, arranged deployment tasks for the team members while taking advantage of the busy gap to give interviews.
“We must seize the opportunity, and the three years of new crown epidemic prevention and control have affected the progress of pilot and demonstration projects of several of our projects.”

On February 3, during the winter break, the Chang’an campus of Shaanxi Normal University in Chang’an District, Xi’an, was particularly silent, while people on the streets outside the campus walls welcomed the Lantern Festival in a peaceful and festive Lunar New Year atmosphere.
Since the establishment of the Institute of Microbial Engineering and Technology of Shaanxi Normal University in January 2018, Chen Wuling has given full play to the advantages of accumulated research and development results, and has taken microbial engineering innovative technology to solve some common problems that the national strategy in the fields of energy, agriculture and the environment needs to be solved urgently, and now has a number of scientific and technological achievements with independent intellectual property rights and leading technology in the field of microbial engineering, and has achieved significant demonstration results in production practice.
Microbial engineering innovations increase oil and gas production

“The microbial enhanced oil recovery technology developed by us uses the metabolic activity of microorganisms to improve the permeability of the reservoir and increase the fluidity of crude oil, thereby increasing crude oil production. The selected breeding microbial flora uses crude oil as the nutrient source, and does not need to inject nutrient solution, which effectively overcomes the problem of short validity period of microbial oil recovery technology. ”
It is understood that from 2021 to 2022, the team carried out a total of 20 gas well scale demonstration applications in Daqing and northern Shaanxi natural gas production plants, with a total gas increase of 4.5 million cubic meters in three months, replacing the original seriously polluting technology.

Since 2018, they have applied the demonstration and research and development of oily sludge harmless treatment technology in Shandong, Xinjiang, Inner Mongolia and other places to dispose of more than 100,000 cubic meters of oily sludge, and restored more than 10,000 mu of polluted arable land. The treated effects all meet the standards of “Technical Requirements for Comprehensive Utilization and Pollution Control of Oily Sludge Resources for Onshore Oil and Gas Exploitation” (SY/T7301-2016), and have passed the acceptance of oilfield and local environmental protection departments.
The innovative results of microbial engineering make the ground green and clear

“Green water and green mountains are gold and silver mountains.” Chen Wuling’s team uses microbial engineering technology to restore polluted and degraded soil and water, and convert solid waste into resources for application in the construction of green development.

The harmless and resource-based treatment technology and process system of urban sludge developed by them has established sludge disposal demonstration projects in Xi’an No. 6 Sewage Plant, Caijiapo Dayuan Sewage Plant and Yulin No. 3 Sewage Plant, with a daily treatment capacity of more than 500 tons. “In 2021, the project was listed as a key demonstration project by the Xi’an Science and Technology Bureau.” Team expert researcher Yao Shengli introduced.
The management of saline-alkali land in arid areas has always been a worldwide problem. They also combine microorganisms with engineering measures to comprehensively treat all types of saline-alkali and desertified land. In the early stage, the treatment of saline-alkali wasteland under different conditions such as Shigatse, Dali, Yuyang and other conditions achieved results, and crops and plants could grow well. In 2020, entrusted by the Yulin Municipal Bureau of Natural Resources and Planning, 200 mu of uncultivated silty soil wasteland with high salinity, high pH, low organic matter and arid silt soil was treated in Tawan Town, Hengshan District. In November 2021, an expert group was organized by the Yulin Municipal Bureau of Natural Resources and Planning to evaluate and accept the project.
In addition, they also completed the demonstration project of ecological restoration of highly saline-alkali polluted water bodies in the Hongjiannuo National Nature Reserve in northern Shaanxi through the microbial engineering technology they developed, and from 2019 to 2021, the team project team completed the ecological restoration of more than 35,000 cubic meters of high saline-alkali lake water. The population and number of organisms in the water body have increased significantly, and the stocked fish have grown and reproduced well.
The innovative achievements of microbial engineering promote the development of green agriculture

Chen Wuling’s research team carried out research and research on the diseases, bagging and splitting fruits that urgently need to be solved in the development of characteristic fruit industries such as apple, kiwifruit, greenhouse melon, red jujube and other characteristic fruit industries in Shaanxi Province, as well as the common blocking points and technical difficulties in the development of green fruit industry such as improving taste quality, and achieved a number of research results that can be applied and promoted on a large scale.

The safe, non-toxic, antibacterial, insect-proof, easy-to-use apple “mask” new biofilm technology developed by them is delicious and safe, and can quickly form a protective film layer with good film-forming, membrane permeability and elongation after spraying the fruit surface, which can effectively protect the surface of the fruit and provide the nutrients required by the fruit. Researcher Ma Qi, former director of Shaanxi Institute of Biological Agriculture, introduced.
The technology has completed the “13115” science and technology innovation project of Shaanxi Province and the agricultural scientific and technological achievements transformation project of the Ministry of Science and Technology, with a demonstration and promotion area of more than 2,000 mu, and established a 660 mu apple bag-free green production demonstration garden in Baishui County.
Based on this technology, the team comprehensively improved the growth, nutrient absorption and disease resistance of fruit trees and fruits in view of the problem of split fruit disease that hindered the industrial development of red jujube producing areas in northern Shaanxi. From 2020 to 2021, the project team of the team cooperated with Shenmu Forestry Bureau to use microbial engineering technology to carry out a total of 1,000 mu of red jujube split fruit disease prevention and control demonstration in Yanhuangsi Town, Shenmu City, with remarkable results. Leaders and experts at all levels of Yulin attended the on-site observation meeting of the Shenmu Red Jujube Anti-Crack Fruit Experimental Project and affirmed the effect of this technology on the anti-cracking fruit of red jujube.
In the development and application of bio-fermented active feed, the team has also achieved certain results.

Take the lead in exploring the road of efficient transformation of scientific research achievements in colleges and universities

“In December 2021, the project ‘Research on the Ecological Restoration of Red Alkali High Saline Water by Microbial Engineering Technology’ participated in the on-site signing ceremony as one of the seven school-enterprise cooperation representative projects of the Shaanxi Provincial Department of Education’s Qinchuangyuan Construction Promotion Association.” Chen Wuling said.

The “Qin Chuangyuan” general platform is a new engine of science and technology development in Shaanxi Province that Shaanxi Province has focused on building in the past two years, so as to break through the “last mile” problem of scientific and technological transformation by building a fully aggregated scientific and technological innovation service system from R&D to incubation to industrialization.

“With the attention and support of the leaders of Shaanxi Normal University, after several years of hard work, our institute has overcome various serious impacts caused by the epidemic in the past three years and various huge difficulties in the implementation of the project, and has initially completed its own basic platform construction, research direction target positioning, technical system improvement, demonstration project establishment, achievement transformation and application, social services and other aspects, laying a solid foundation for the next rapid development.” Chen Wuling spoke with deep feelings about the development process in recent years.

It is understood that in January 2018, Shaanxi Normal University established the Institute of Microbial Engineering and Technology of Shaanxi Normal University in the form of the overall introduction of the team, from the employment contract signed between Shaanxi Normal University and the Institute to assess the content and work objectives, etc., the team is to focus on the field of microbial engineering technology, to undertake major scientific and technological projects and the transfer of scientific and technological achievements into goals, carry out technological innovation and research, solve key common technical problems in the industry and industry, implement the transfer and transformation of scientific and technological achievements, and serve local economic and social development. This is also a pioneering measure to explore the efficient transformation of scientific research achievements in Chinese universities.
Chen Wuling stressed that at present, there are still some blocking points in the “production, education and research” collaborative mechanism of China’s green technology innovation, and the efficiency of market application transformation is not high. Our original intention is to carry out the research and development of breakthrough key green core technologies and form an innovation system in multiple dimensions based on the green technology and market orientation needed in the country’s development, so as to jointly promote carbon reduction, pollution reduction, green expansion and growth.
Chen Wuling said that with the continuous strong support of the university, the institute will make full use of the “Qin Chuangyuan” platform and related policies, continuously strengthen the cohesion of innovation synergy, do a good job in coordination and cooperation, benefit sharing, and contribute to exploring the transfer and transformation of scientific research achievements in universities.
