Actualmente la potencial aplicación de bacterias acido lácticas (BAL) en los sistemas de tratamiento de agua se visualiza como una solución a la producción de agua potable y al tratamiento de aguas residuales, debido a la alta demanda por fuentes de abastecimiento y al aumento del vertimiento de aguas tratadas, debido al incremento de las actividades industriales y el crecimiento poblacional. Bajo este contexto y como respuesta a esta demanda se está recurriendo al tratamiento de fuentes naturales contaminadas, aumentando significativamente su costo. Por ello, el uso de este tipo de bacterias en el agua se muestra como una alternativa, al ser tecnologías de bajo costo que se incorporan al reciclaje de agua, biodegradables y que no generan derivados peligrosos producto del tratamiento. En las fuentes de captación naturales, existen comunidades bacterianas dentro de las cuales es posible encontrar poblaciones de BAL de vida libre, las cuales poseen un rol de protección del ambiente dulceacuícola, dada su versatilidad y propiedades probióticas. Se ha visto que poseen efectos en la remoción de metales pesados del agua, por mecanismos biológicos tales como biosorción y bioacumulación, disminuyendo su presencia en el medio circundante. En este artículo se presenta una revisión respecto al uso de BAL en la biorremediación de sistemas acuícolas, especialmente respecto de su contaminación por metales pesados, con el fin de ser utilizadas en los sistemas de tratamiento de agua del sur de Chile central, entregando a profesionales del ámbito sanitario, una alternativa para la producción de agua de buena calidad.

“…Lactic acid bacteria (LAB) are not considered typical members of the freshwater microbial communities as they generally are associated with terrestrial plant materials, animals and food products (Di Cagno et al, 2013; Duar et al, 2017; Endo et al, 2009; Groenewald et al, 2006; Koch & Schmid‐Hempel, 2011; Krumbeck et al, 2016; Martin & Mundt, 1972; Rokop et al, 2015; Ruiz Rodríguez et al, 2019). Thus, relatively few studies report their presence in freshwater environments, such as ponds, lakes and pristine brooks (Korzeniowski et al, 2020; Leisner et al, 2008; Manes‐Lazaro et al, 2009; Niemi et al, 2012; Signoretto et al, 2004; Yanagida et al, 2007). The composition of microbial communities of freshwater differs to some degree from those encountered in terrestrial and marine habitats (Newton et al, 2011; Pernthaler & Amann, 2005) but smaller freshwater systems, such as ponds, bogs and springs, may to a larger degree be affected by influx from the surrounding terrestrial environment.…”

We explored the distribution, metabolic and antagonistic activities of Carnobacterium maltaromaticum, isolated from freshwater locations in Denmark during winter or early spring. This species was widely distributed in such habitats although it was relatively rare in low pH locations. Isolates possessed a diverse metabolism, potentially enabling functional capacities independent of habitat. The intraspecies competition showed a relatively high degree of mostly low‐intensity interactions, which overall were not correlated with phylogeny or location. Only a few isolates exhibited broad‐spectrum inhibition activity, targeting species from other genera and families, including one isolate that exhibited a broad inhibitory activity due to H2O2 production. Bioinformatic analyses revealed that the frequency of bacteriocinogenic systems was low, and only one unmodified bacteriocin, piscicolin 126, correlated with phenotypic antagonistic activity. Furthermore, most potential bacteriocin gene complexes were not complete. Overall, this study showed C. maltaromaticum to be a generalist (nomadic) species with a constant presence in freshwater habitats, especially those with pH values >5. General metabolic properties did not suggest a strong degree of adaptation to the freshwater environment, and bacteriocin‐mediated antagonistic activities appeared to play a minimal ecological role.

“…The natural habitats of the motile lactobacilli are variable, such as sewage, freshwater pond, stinky tofu brine, cocoa, cider, wine, shochu, oak tree, grape must, kaburazushi, chicken, horse and human [7][8][9][10][11][12][13][14][15][16][17]. Of the motile lactobacilli, L. agilis and L. ruminis are the only known species originating from animal and human guts [18,19].…”

PCR-based screening, isolation, and partial characterization of motile lactobacilli from various animal feces

et al. 2020

Background Most lactobacilli found in animal intestines are generally non-motile, but there are few exceptions. Our previous work showed that Lactobacillus agilis BKN88, which is a highly motile strain originating from a chicken, takes advantage of motility in gut colonization in murine models, and thus motile lactobacilli likely have unique ecological characteristics conferred by motility. However, the ecology and habitat of gut-derived motile lactobacilli are still rarely understood. In addition, the limited availability of motile Lactobacillus isolates is one of the major obstacles for further studies. To gain insight into the ecology and habitat of the motile lactobacilli, we established a routinely applicable detection method for motile lactobacilli using PCR and subsequent selective isolation in semi-solid MRS medium for the collection of additional motile lactobacilli from animal feces. Results We applied the PCR detection using motile lactobacilli-specific primers, based on the motor switch protein gene (fliG) of flagella, to 120 animal feces, followed by selective isolation performed using 45 animal feces. As a result, motile lactobacilli were detected in 44 animal feces. In the selective isolation, 29 isolates of L. agilis and 2 isolates of L. ruminis were obtained from 8 animal species. Conclusions These results indicated that motile lactobacilli are distributed in different animal species. Moreover, phylogenetic analysis of the L. agilis isolates suggests co-evolution with the host, and adaptation to a particular environmental niche.
