Lactic acid bacteria from fresh fruit and vegetables as biocontrol agents of phytopathogenic bacteria and fungi.
TLDR
The results support the potential of LAB as biocontrol agents against postharvest rot as well as previous reports of antifungal activity by LAB.Abstract:
Summary. This study evaluated the efficacy of lactic acid bacteria (LAB) isolated from fresh fruits and vegetables as biocontrol agents against the phytopathogenic and spoilage bacteria and fungi, Xanthomonas campestris, Erwinia carotovora, Penicillium expansum, Monilinia laxa, and Botrytis cinerea. The antagonistic activity of 496 LAB strains was tested in vitro and all tested microorganisms except P. expansum were inhibited by at least one isolate. The 496 isolates were also analyzed for the inhibition of P. expansum infection in wounds of Golden Delicious apples. Four strains (TC97, AC318, TM319, and FF441) reduced the fungal rot diameter of the apples by 20%; only Weissella cibaria strain TM128 decreased infection levels by 50%. Cell-free supernatants of selected antagonistic bacteria were studied to determine the nature of the antimicrobial compounds produced. Organic acids were the preferred mediators of inhibition but hydrogen peroxide was also detected when strains BC48, TM128, PM141 and FF441 were tested against E. carotovora. While previous reports of antifungal activity by LAB are scarce, our results support the potential of LAB as biocontrol agents against postharvest rot. [Int Microbiol 2008; 11(4):231-236].read more

TL;DR: It critically evaluates control methods used in practice based on the avoidance of the contamination of plants, in particular the use of seed testing programmes and the application of hygienic procedures during crop production and examines the possibility of biocontrol using antagonistic bacteria and bacteriophages.

Antimicrobial activity of bacteriocin-producing lactic acid bacteria isolated from cheeses and yogurts
TL;DR: Bacteriocinogenic LAB present in cheeses and yogurts may have potential to be used as biopreservatives in foods and organic acids produced by LAB and not the BLS had strong antimicrobial effects on all microorganisms tested with the exception of E. coli.

Antimicrobial peptide genes in Bacillus strains from plant environments.
TL;DR: The dominance of these particular genes in Bacillus strains associated with plants reinforces the competitive role of surfactin, bacyllomicin, fengycin, and bacilysin in the fitness of strains in natural environments.

Biofilm exopolysaccharides: a strong and sticky framework.
TL;DR: Wimpenny & Colasanti (1997) have suggested that biofilm structure is largely determined by the concentration of substrate, and postulated that such differences also validate at least three conceptual models of biofilms – heterogeneous mosaics, structures penetrated by water channels, and dense confluent bioFilms.

TL;DR: A total of 221 strains of Lactobacillus isolated from meat and meat products were screened for antagonistic activities under conditions that eliminated the effects of organic acids and hydrogen peroxide, indicating that this substance is a bacteriocin, which was designated sakacin A.

TL;DR: The vast surface of the plant axis, stretching from root tips occasionally buried deeply in anoxic sediment, to apical meristems held far aloft, provides an extraordinarily diverse habitat for microorganisms.

Identification of lactobacilli from meat and meat products
TL;DR: Schemes for a rapid and simple identification of lactobacilli from meat and meat products are presented, which also include the species only recently published and which permit a rapid assignment of a new isolate to one of the Lactobacillus species.
