Effect of Zingiber officinale essential oil on Fusarium verticillioides and fumonisin production

Abstract

The antifungal activity of ginger essential oil (GEO; Zingiber officinale Roscoe) was evaluated against Fusarium verticillioides (Saccardo) Nirenberg. The minimum inhibitory concentration (MIC) of GEO was determined by micro-broth dilution. The effects of GEO on fumonisin and ergosterol production were evaluated at concentrations of 500-5000 μg/mL in liquid medium with a 5mm diameter mycelial disc of F. verticillioides. Gas chromatography-mass spectrometry showed that the predominant components of GEO were α-zingiberene (23.9%) and citral (21.7%). GEO exhibited inhibitory activity, with a MIC of 2500 μg/mL, and 4000 and 5000 μg/mL reduced ergosterol biosynthesis by 57% and 100%, respectively. The inhibitory effect on fumonisin B1 (FB1) and fumonisin B2 (FB2) production was significant at GEO concentrations of 4000 and 2000 μg/mL, respectively. Thus, the inhibition of fungal biomass and fumonisin production was dependent on the concentration of GEO. These results suggest that GEO was able to control the growth of F. verticillioides and subsequent fumonisin production.

Antimicrobial Activity of Essential Oil of <i>Zingiber officinale</i> Roscoe (Zingiberaceae)

“…The lipophilic character of its hydrocarbon backbone and hydrophilic character of some of its functional groups confer this property [31] ( [28]. The authors mention that essential oils with high concentrations of sequiterpenes possess greater antibacterial and antifungal activity.…”

Antifungal properties and inhibitory effects upon aflatoxin production of Thymus vulgaris L. by Aspergillus flavus Link

“…and Aspergillus sp. (Bomfim et al, in press;Ferreira et al, 2013;Omidbeygi, Barzegar, Hamidi, & Naghdibadi, 2007;Yamamoto-Ribeiro et al, 2013). Within this context, essential oils have been studied as an alternative method for controlling of microorganism proliferation in foods and grains stored for longs periods of time.…”

Effect of cinnamon essential oil and cinnamaldehyde on Salmonella Saintpaul biofilm on a stainless steel surface

“…The oil was collected, dried over sodium sulfate, and stored in an amber flask at 4 C. The yield of the oil was 0.92% v/w. The EO chemical composition was investigated by gas chromatography-mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR) according to Yamamoto-Ribeiro et al (2013).…”
