Induction of a viable-but-non-culturable state in bacteria treated with gas discharge plasma.Comments Comment on: J Appl Microbiol. 2010 Dec;109(6):2039-48; PMID: 20825520

摘要

The article by Cooper et al. (2010) deals with the use of plasma to inactivate micro-organisms and concludes that plasma induces bacteria to enter a viable-but-non-culturable (VBNC) state, probably due to oxidative stress. The authors correlate viability results with morphological ones, and they propose that longer exposure times may be needed to ensure complete cell death. Their approach is interesting, but the paper does not report novel aspects. In fact, their approach and conclusions are almost identical to previous contributions from our group, although we are not referenced in their paper.
