Antibiotic Algae by Chemical Surface Engineering


Kerschgens, Isabel P; Gademann, Karl (2018). Antibiotic Algae by Chemical Surface Engineering. Chembiochem, 19(5):439-443.

Abstract

Chemical cell-surface engineering is atool for modifying and alteringcellular functions. Herein, we report the introduction of an antibiotic phenotype to the green alga Chlamydomonas reinhardtii by chemically modifyingits cell surface. Flow cytom- etry and confocal microscopy studies demonstrated that a hybrid of the antibiotic vancomycin anda4-hydroxyproline oligomer binds reversibly to the cell wall without affecting the viability or motility of the cells. The modified cells were used to inhibit bacterial growth of Gr am-positive Bacillus subtilis cultures.Deliveryofthe antibiotic from the microalgaetothe bacterialcells was verified by microsco py.Our studies provid e compelling evidence that 1) chemical surfaceengineering con- stitutesauseful tool for the introductionofnew,previously unknown functionality,and 2) living microalgae can serve as new platforms for drug delivery.
