Jankovic, T.J. (author), Straathof, Adrie J.J. (author), Kiss, A.A. (author)Isobutanol is a highly attractive renewable alternative to conventional fossil fuels, with superior fuel properties as compared to ethanol and 1-butanol. Even though the isobutanol production by fermentation has significant potential, complex downstream processing is limiting the wide-spreading of this technology. Accordingly, this original...journal article 2024

Ma, Yunjian (author), Zhong, Xuanru (author), Wu, Bin (author), Lan, Dongming (author), Zhang, Hao (author), Hollmann, F. (author), Wang, Yonghua (author)Hydrocarbons are essential base chemicals as energy carriers and starting materials for chemical manufacture. So-called fatty acid photodecarboxylases (FAPs) represent interesting catalysts for the conversion of natural fatty acids into hydrocarbons thereby giving access to alkanes from renewable feedstock. Today, however, only few FAPs are...journal article 2023

Chanquia, Santiago Nahuel (author), Benfeldt, Frederik Vig (author), Petrovai, Noémi (author), Santner, Paul (author), Hollmann, F. (author), Eser, Bekir Engin (author), Kara, Selin (author)Since its discovery in 2017, the fatty acid decarboxylase (FAP) photoenzyme has been the focus of extensive research, given its ability to convert fatty acids into alka(e)nes using merely visible blue light. Unfortunately, there are still some drawbacks that limit the applicability of this biocatalyst, such as poor solubility of the...journal article 2022
