What are the realistic ways of application of LAB as a safe biopreservation tools in
food fermentation processes?

n last few decades’ research for an appropriate starter
culture combining different beneficial properties from
technological, biopreservation, bacteriocin production to
the probiotic’s characteristics been explored by for different
LAB cultures by several research groups. The challenge of
combining different disable characteristics in a same starter
culture was faced. Different approaches were applied, and
results were a development of innovative applications of LAB
in biopreservation of fermented meat products. However,
with the development of different branches of the life
sciences and build of new knowledge in microbiology new
challengeswere faced. Traditional knowledge on safety of LAB
was not any more sufficient to certificate safe application of
used for centuries LAB starter cultures. Besides all beneficial
properties studied for various LAB, a special attention
needs to be pay on the safety of LAB: the possible presence
of virulence factors, production of biogenic amines and
antibiotic resistance. This virulence determinants have been
well detected and studied in Enterococci and Streptococci,
however, in last few years report on presence of virulence
factors in otherwise GRAS Lactobacilli have been showing
the potential upcoming problems. Horizontal gene transfer
of virulence factors between pathogenic and LAB, including
probiotics is a highly possible scenario in case of uncontrolled
application of probiotics.
In this overview we focus of application of beneficial LAB in
production of fermented food products, however, we point
attention of some challenges that this process can face. How
this can be solved, what are the realistic way of application
of LAB as a useful tool of biopreservation and what are the
limitation?Where is the limit between reality and fiction? Are
LAB safe for industrial application and what are limitations?
