Biochemical engineering - from microreactors to filamentous microorganisms

Seminario
With the expansion of the biotechnology and environmental technology industries, biochemical engineering emerged as an independent engineering discipline in the mid-1980s. Today, biochemical engineering plays an important role in many everyday areas. It makes an outstanding contribution, particularly in the manufacture of pharmaceutical products. It is also involved in the development of sustainable manufacturing processes based on renewable raw materials and thus makes a decisive contribution to environmental protection and resource conservation. Climate change, scarcity of resources and a growing world population have once again rapidly increased the importance and public awareness of this subject in connection with bio-based processes in recent years.
In order to be able to transfer biological and biochemical material conversion processes from the laboratory to an industrial scale and to realize them technically, biological, biotechnological and chemical knowledge is required in biochemical engineering in addition to the knowledge of classical process engineering. The subject therefore acts as a bridge between the natural sciences and engineering disciplines.
The main tasks of biochemical engineering consist of
- the quantitative detection of biotechnological processes, i.e. material conversions by biocatalysts (enzymes, cells),
- the design of suitable bioreactors and apparatuses and
- the transfer of laboratory results and theoretical concepts into practice and technical scale (scale up).
The UNAM seminar introduces the most important fundamentals and process parameters for the technical application of biotechnological processes. Methods of the biotechnological sub-areas of enzyme technology, the production of new antibiotics using filamentous microorganisms and the development of microbioreactors for biotechnological screening processes are examined and discussed using current examples.

Membrane remodeling by ESCRT proteins in plant cells
The dynamic flow of proteins to and from the plasma membrane and between organelles is crucial for cellular function, signaling, and development. We study the cellular functions and biophysical properties of ESCRT proteins to uncover the fundamental principles governing membrane remodeling in plants and other organisms. ESCRT proteins are essential for endosomal trafficking of plasma membrane molecules as well as many other crucial cellular events. However, we are still far from understanding how ESCRTs mediate membrane remodeling in the context of all their many cellular functions. Using live imaging, electron tomography, genetics, biochemistry, structural biology, and computational modeling, we analyze endosomal membrane vesiculation in several plant lineages and other organisms to understand the common principles that underlie ESCRT membrane bending. We also have uncovered novel functions of ESCRT proteins in cell plate maturation during cytokinesis, nuclear dynamics, and epidermal cell differentiation. These findings are helping us to elucidate basic mechanisms essential for cell function and plant development, with broader implications for cell biology and plant biotechnology.
