Anotace: This publication is a sequel to the study Microbiology of brewing – Kocuria (Micrococcus) and cultivation methods for their detection – part 1 (Matoulková and Kubizniaková, Kvasny Průmysl 64(1): 10–13, 2018). Growth was monitored in a set of 8 strains of Kocuria and Micrococcus on solidified culture media, e.g. MRS agar and its various modifications, the media Raka-Ray, NBB, UBA, etc. Under aerobic conditions, most strains of Kocuria were able to grow on UBA agar, which is designed to detect beer harmful microorganisms. Thus there is a higher likelihood of confusion of Kocuria with more risky Pediococcus and vice versa in laboratories, which do not apply anaerobic incubation conditions to detect lactic acid bacteria.
