Effect of laser bioprinting on growth characteristics of yeasts

Abstract

Laser-induced forward transfer (LIFT) can be helpful for bioprinting of microbial cells, but data on its impact on the microbial physiology are scarce. The aim of study was to investigate the LIFT effect on eukaryotic microorganisms (yeasts) growth characteristics. Candida albicans, Lipomyces lipofer and Saitozyma podzolica yeasts were printed on solid and liquid nutrient media and compared with traditional methods of inoculation. The laser bioprinting affects growth patterns of yeasts, leading to formation of subpopulations with different growth characteristics. The data obtained highlight necessity of studies of the LIFT effect on microorganisms’ physiology.
