In general, industrial biotechnology approaches provide access to many different substance groups in this segment. The institute has decades of expertise in the identification, modification and cultivation of microorganisms or the use of enzymes, which, coupled with know-how and technologies from the field of interfacial engineering, enable new products and applications. Examples of particularly interesting product groups are surface-active substances such as surfactants or biobased coating systems. We also focus on the synthesis and characterization of substances and materials for which an interaction with biological systems plays an essential role. Examples here include additives for agriculture such as plant boosters made of microalgae, which positively impact cell growth in agricultural crops.
