Medical biotechnology is technical solutions using biological properties of cells and of biological moleculars for diagnosis, treatment and prophylaxis. Considerable achievements were gained in Vietnam despite it was applied lately and the investment in medical biotechnology is lower. These achievements include early detection and diagnosis of genes causing cancers like throat-nose cancer, liver cancer, some bacterial and viral infections, some hereditary diseases, bio-products for treatment like anti-rabies serum, anti-venom serum, and vaccines for diphtheria, pertussis, tentanus, hepatitis B, hepatitis A (Havax), Japanese encephalitis, polio and typhoid.

The construction of "Emerging Engineering Education" aims at cultivating high-quality graduates capable of engineering practice, innovation and international competitiveness. Bilingual courses have become one of the effective means to cultivate qualified students with skills of both professional knowledge and international communication. However, the teaching effect of most bilingual courses is not very ideal. Based on analyzing common problems in the current bilingual teaching, we take the bilingual course of environmental biotechnology as an example, and discusses possible improvement strategies from the aspects of the construction of teaching mode, the establishment of quality control system, the selection of textbooks and the optimization of assessment methods. Moreover, we summarize experience and shortcomings on improving the lecturers' ability, students' learning enthusiasm and school's support. It is expected to provide useful reference for improving the effect of bilingual teaching in biotechnology-relevant courses.

Improving the creativity is crucial to postgraduate training nowadays. The course of Modern Microbial Biotechnology is an optional specialized course for microbiology-related postgraduates. To explore a new teaching mode for improving the creativity of postgraduate students, we reformed the teaching content, the teaching method and the evaluation mode of this course. Through case study teaching, seminar-style classroom and implementation of a new assessment method, the students not only mastered professional knowledge and disciplinary frontiers of modern microbiology technology, but also improved their ability of discovering, analyzing and solving problems. The reformed course teaching mode is effective in fostering postgraduates' creativity.

Industrial biotechnology promises to make a significant contribution in enabling the sustainable development, and need the solid support from its basic discipline. As the basis of industrial biotechnology, industrial biology is to study the basic laws and mechanisms of biological behavior in industrial environment and to solve the key scientific problems for understanding, designing and constructing the organisms adapted to the application of industrial environment. In order to comprehend the status of industrial biology, we published this special issue to review the progress and trends of industrial biology from the three aspects of industrial protein science, cell science and fermentation science, respectively, for laying the foundation for the development of industrial biotechnology.

Based on the demand of enterprise talents and the characteristics of manufacturing process management in biotechnology, in order to make the students acquire the ability to solve complex engineering problems in the production process, we developed a "Comprehensive Biotechnology Experiment" course, where two-step enzymatic production of l-aspartate and l-alanine were the key processes. In this course, we drew lessons from the site management of the production enterprise, performed the experimental operation mode of four shifts and three operations. The content of this course includes principles, methods and experimental techniques of several core curricula and the site management mode of enterprises. As to the evaluation, the summary of the experimental staff's handover records and the content of teamwork were examined and scored. Through teaching practice and continuous improvement, we developed a complete experimental teaching process and assessment mechanism. Overall, the Comprehensive Biotechnology Experiment course achieved good teaching effect, which may serve as a reference to promote the development of experimental teaching of biotechnology.

Based on recently developed biotechnology, many new drugs have been developed for improving patient treatment outcomes. To develop novel drugs, proper clinical trials are essential. As clinical trials involve humans in research, the protection of participants is important not only for the participants' safety but also for future patients. Ethics in a clinical trial is not the same as in clinical practice with enough evidence. Hence, the whole procedure of a clinical trial should be well organized, scientifically and ethically planned, and monitored properly by an Institutional Review Board (IRB). Here the importance of ethics in clinical trials, related issues, and the monitoring system will be discussed.

Synthetic plastics have been widely used in various fields of the national economy and are the pillar industry. However, irregular production, plastic product use, and plastic waste piling have caused long-term accumulation in the environment, contributing considerably to the global solid waste stream and environmental plastic pollution, which has become a global problem to be solved. Biodegradation has recently emerged as a viable disposal method for a circular plastic economy and has become a thriving research area. In recent years, important breakthroughs have been made in the screening, isolation, and identification of plastic-degrading microorganisms/enzyme resources and their further engineering, which provide new ideas and solutions for treating microplastics in the environment and the closed-loop bio-recycling of waste plastics. On the other hand, the use of microorganisms (pure cultures or consortia) to further transform different plastic degradants into biodegradable plastics and other compounds with high added value is of great significance, promoting the development of a plastic recycling economy and reducing the carbon emission of plastics in their life cycle. We edited a Special Issue on the topic of "Biotechnology of Plastic Waste Degradation and Valorization", focusing on the researches progress in three aspects: Mining microbial and enzyme resources for plastic biodegradation, Design and engineering of plastic depolymerase, and biological high-value transformation of plastic degradants. In total, 16 papers have been collected in this issue including reviews, comments, and research articles, which provide reference and guidance for further development of plastic waste degradation and valorization biotechnology.

In recent years, the petroleum-based plastic pollution problem has been causing global attention. The idea of "degradation and up-cycling of plastics" was proposed for solving the environmental pollution caused by non-degradable plastics. Following this idea, plastics would be firstly degraded and then reconstructed. Polyhydroxyalkanoates (PHA) can be produced from the degraded plastic monomers as a choice to recycle among various plastics. PHA, a family of biopolyesters synthesized by many microbes, have attracted great interest in industrial, agricultural and medical sectors due to its biodegradability, biocompatibility, thermoplasticity and carbon neutrality. Moreover, the regulations on PHA monomer compositions, processing technology, and modification methods may further improve the material properties, making PHA a promising alternative to traditional plastics. Furthermore, the application of the "next-generation industrial biotechnology (NGIB)" utilizing extremophiles for PHA production is expected to enhance the PHA market competitiveness, promoting this environmentally friendly bio-based material to partially replace petroleum-based products, and achieve sustainable development with carbon-neutrality. This review summarizes the basic material properties, plastic upcycling via PHA biosynthesis, processing and modification methods of PHA, and biosynthesis of novel PHA.
