“…Due to the antimicrobial activity of EOs (Sandasi et al, 2008) it is necessary to test the effect of EO on biofilm formation of PPCB004 exposed to LO or TO. The effect of TO and LO treatments on biofilm formation is shown in Fig.…”

“…Recent studies suggested that the biofilm mode is important for the bacteria's ability to act as biocontrol agents (Bais et al, 2004). Monoterpene components of EO increased the biofilm formation in gram positive bacteria (Sandasi et al, 2008). Therefore, combined treatment of biocontrol agent B. amyloliquefaciens and EOs in a postharvest system may be beneficial to control the incidence of postharvest diseases during storage and transportation of peaches especially for organic growers.…”

a b s t r a c tBacillus amyloliquefaciens PPCB004 was selected as a potential antagonist to control Botrytis cinerea, Penicillium expansum and Rhizopus stolonifer on peach fruit. The HPLC data of PPCB004 indicated the lipopeptides iturin A, fengycin and surfactin as secondary metabolites. The GC/MS analysis of PPCB004 showed 3-hydroxy-2-butanone as the dominant compound (97.52% of relative peak area). Thyme (TO) and lemongrass (LO) oils showed over 50% and 25% inhibition of radial mycelial growth respectively with 8 ml oil per plate for all pathogens. Combination treatment with both oils failed to increase the percentage inhibition of radial mycelial growth of the pathogens. Combined application of PPCB004 with TO or LO was tested to assess the effectiveness in the control of these pathogens during postharvest storage. The biofilm formation of PPCB004 was significantly higher in LO than TO. LO (6 ml plate À1 ) and PPCB004 completely inhibited the mycelial growth of the pathogens. Fruit inoculation trials with PPCB004 þ LO in NatureFlexÔ modified atmosphere packaging (MAP), showed lower disease incidence and severity at 25 C for 5 d than treatments with PPCB004 þ MAP, PPCB004 þ TO þ MAP, LO þ MAP, TO þ MAP or stand-alone MAP. On naturally infected fruit, PPCB004 þ LO þ MAP and LO þ MAP treatments retained the total soluble solids/titratable acidity ratio and flesh firmness but failed to stimulate the levels of total phenolic content, phenylalanine ammonia-lyase, b-1,3-glucanase and chitinase activities. Combination of PPCB004 (spray treatment) þ LO (in pad delivery system) in NatureFlexÔ MAP showed absence of disease and off-flavour development, retained the overall appearance and increased the overall acceptance at market shelf conditions (20 C for 2 d) after cold storage at 4 C for 14 d.

“…Natural antimicrobial products can be attractive to the food industry in that they control natural spoilage microorganisms (Tajkarimi et al, 2010). Previous studies (Oussalah et al, 2007;Sandasi et al, 2008) have demonstrated that essential oils from selected plants inhibited the growth of four pathogenic bacteria (Escherichia coli O157:H7, Listeria monocytogenes, Salmonella Typhimurium, and Staphylococcus aureus) and reduced the metabolic activity of L. monocytogenes biofilms.…”

Biofilms are a problem to food industries, causing equipment damage, increased energy costs, and food spoilage, and they are a potential harbour of pathogenic microorganisms. Their extreme anti-microbial resistance means that novel control strategies are necessary. Plant secondary metabolites (phyto-chemicals) have demonstrated promising antimicrobial properties when applied against planktonic cells and biofilms. The aim of this study was to test the effectiveness of two phenolic acids: ferulic (FA) and salicylic (SA), alone and in combination (FSA) on the prevention and control of Bacillus cereus and Pseudomonas fluorescens biofilms. Additional tests were performed to ascertain the effects of FA and SA on bacterial motility, surface properties (physicochemical properties and surface charge), and quorum sensing inhibition (QSI). The effects of a concentration two times the minimum inhibitory concentration (500 g mL -1 ) were assessed on single-and dual-species biofilms. The results demonstrated that only swimming was affected by FA and SA and no clear relationship was obtained between the effects of phenolic acids on motility and biofilm prevention. The bacterial physico-chemical surface properties and charge were affected by the phenolic acids. Salicylic acid demonstrated capacity for QSI. However, both bacteria were able to form single-and dual-species biofilms in the presence of the phenolic acids. The application of FA and SA (single and combined) to biofilms caused low to moderate inactivation and removal. However, dual-species biofilms formed in the presence of phenolic acids were highly susceptible to a second exposure to the chemicals. The continuous exposure of dual-species biofilms to the phenolic acids decreased their resilience and resistance to inactivation and removal. This study clarifies the role of FA and SA in the prevention and control of biofilms formed by two important food spoilage bacteria.2

It has long been shown that phytochemicals protect plants against viruses, bacteria, fungi and herbivores, but only relatively recently we have learnt that they are also critical in protecting humans against diseases. A significant amount of medicinal plants is consumed by humans. As food-related products, they additionally improve human health and general well-being. This chapter deals with plant-derived food preservatives. Particular attention has been paid to the following berry fruits: cranberry (Vaccinium macrocarpon), bilberry (Vaccinium myrtillus), black currant (Ribes nigrum), elderberry (Sambucus nigra), cornelian cherry (Cornus mas) and açaí (Euterpe oleracea), as well as the following herbs and spices: peppermint (Mentha piperita), basil (Ocimum basilicum), rosemary (Rosmarinus officinalis), thyme (Thymus vulgaris), nettle (Urtica dioica), cinnamon (Cinnamomum zeylanicum) bark, cloves (Syzygium aromaticum) and licorice (Glycyrrhiza glabra) as alternative sources of natural antimicrobial and antibiofilm agents with potential use in food industry. Moreover, we present an overview of the most recent information on the positive effect of bioactive compounds of these plants on human health. This chapter is a collection of essential and valuable information for food producers willing to use plant-derived bioactive substances for ensuring the microbiological safety of products.
