It is well known that traditional methods of destroying biofilms by biocides is environmentally unfriendly
and takes about 24 h. In contrast, Figs. 7 and 8 show that NTP jet can destroy biofilm by a much
shorter exposure time (tens of seconds in the case of treatment in ambient air, and hundreds of seconds
in the case of treatment in liquid). Data presented in Fig. 7 show that aerobic heterotrophs have higher
resistance against active plasma agents compared with the sulfate-reducing bacteria. Taking this into account,
we focused mainly on studying the survival of the aerobic heterotrophs. In the case of biofilms
