The assay was performed using medium with and without sorbitol (control) to evaluate possible mechanisms involved in the antifungal activity of the test product on the yeast cell wall. The sorbitol was added to the culture medium in a final concentration of 0.8 M. The assay was performed by microdilution method in 96-well plates in a “U” (Alamar, Diadema, SP, Brazil). The plates were sealed aseptically, incubated at 35°C, and readings were taken at 2 and 7 days. Based on the ability of sorbitol to act as a fungal cell wall osmotic protective agent, the higher MIC values observed in the medium with added sorbitol compared to the standard medium implicated the cell wall as one of the possible cell targets for the product tested [36 (link)]. Amphotericin B was used as the control drug. The assay was performed in duplicate and expressed as the geometric mean of the results.

To assess if the product binds to the fungal membrane sterols, this experiment was performed according to the method described by Escalante et al. [37 (link)], with some modifications. The ergosterol was prepared at the time of test execution, where it was first pulverized (with the help of a pre-sterilized porcelain mortar and pestle) and dissolved in DMSO (no more than 10% of final volume), and Tween 80 at 1%, in accordance with the desired concentration and volume. The formed emulsion was then homogenized, heated to augment the solubility, and diluted with the liquid culture medium.
The MIC of citral against C. albicans was determined by using broth microdilution techniques according to the guidelines of the CLSI for yeasts (M27-A2) [27 ], in the presence and absence of exogenous ergosterol (Sigma-Aldrich, São Paulo, SP, Brazil) added to the assay medium, in different lines of the same microplate. Briefly, a solution of citral was doubly diluted serially with RPMI-1640 (volume = 100 μL) containing plus ergosterol at a concentration of 400 μg/mL. A volume of 10 μL of yeast suspension (0,5 McFarland) was added to each well. Finally, we realized the same procedure for amphotericin B, whose interaction with membrane ergosterol is already known, which served as a control drug. The plates were sealed and incubated at 35°C. The plates were read after 24 h of incubation and MIC was determined as the lowest concentration of test agent inhibiting the visible growth. This assay was carried out in duplicate and the geometric mean values were calculated. Thus, this binding assay reflected the ability of compound to bind with the ergosterol.

Plasma membrane integrity of the P. digitatum cells with citral (0 or 1/2MIC) were analyzed by propidium iodide (PI) staining coupled with fluorescence microscopy (Liu et al., 2010 (link)) with minor modifications. The 2-day-old mycelia from 50 mL PDB were collected and centrifuged at 4,000 g for 10 min. The collected mycelia were stained with 10 μg/mL of PI for 15 min at 30°C. Residual dyes were removed by washing twice with PBS (pH 7.0). Samples were observed with an ECLIPSE TS100 microscope (Nikon, Japan), and the fluorescence value was determined by a F97 PRO fluorescence spectrophotometer (Lengguang Technology, Shanghai, China). These experiments were also performed with antioxidant Cys at a concentration of 10 μM.

RNA was extracted from P. digitatum cells exposure to citral at various concentrations (0 and 1/2MIC) for 0, 30, 60, and 120 min using the Trizol reagent (Invitrogen, USA) following the manufacturer’s instructions. Two micrograms of DNA-free RNA were used for reverse transcription by M-MLV (Promega, USA) with oligo dT18. RTFQ-PCR was performed on a BIO-RAD CFX Connect Thermal Cycler using FastStart Universal SYBR Green Master (Roche, Switzerland). All primer pairs for expression assays are listed in Table 1. RTFQ-PCR was programmed as follows: 95 °C for 10 min followed by 40 cycles of 95 °C for 15 s, 60 °C for 1 min. The 2-△△CT method was used to quantify the value of every sample using actin gene as an internal reference [27 (link)].

The growth curves in TSB at 37°C were determined as previously described [17 ]. C. sakazakii strain ATCC 29544 was grown to an OD600 value of 0.1 in TSB, then 125 μL of the culture was transferred into each well of a 96-well microtiter plate (Nunc, Copenhagen, Denmark). Citral was added to the cultures to obtain final concentrations of 1/16MIC, 1/8MIC, 1/4MIC, 1/2MIC, and MIC, and TSB was used as a negative control. Bacteria were further cultured at 37°C, and cell growth was monitored at 600 nm using a multimode plate reader (Tecan, Infinite M200 PRO, Männedorf, Switzerland).
The model used to fit growth curves to the data as-obtained was comprised of a modified Gompertz equation as follows:
ODt=A+(BA)exp{exp[−μ(tM)]}
λ=M(1/μ), and umax=(BA)μ/e
where ODt is optical density at 600 nm (OD600) at time t, t is the time (in hours) that had elapsed since incubation, B is the maximum OD600, A is the initial OD600, M is the time (in hours) of the inflexion point in the exponential phase of model function, μ is the relative growth rate at time M, λis the lag time (i.e., the time until the lag period ended,) and μmax is the maximum growth rate achieved (ΔOD600 per hour.) The model was evaluated for goodness of fit according to the coefficient of determination R2.

Water and methanol extracts of Australian native lemongrass were used to determine the citral content. The HPLC-PDA method was used to determine citral content in extracts using the instrumental method described previously [37] (link). A reverse-phase Waters ® HSS-T3 column (150 mm × 2.1 mm i.d; 1.8 µm, Waters, Sydney, NSW, Australia), maintained at 25 • C, was used to separate the compounds with mobile phases consisting of 0.1% formic acid in Milli-Q water (mobile phase A) and 0.1% formic acid in acetonitrile (mobile phase B). The gradient program applied at the flow rate of 0.2 mL/min was as follows: 5% B-1 min, 70% B-4.3 min, isocratic elution at 70% B until 8 min, 95% B-10 min, isocratic at 95% B until 12 min, and ramped back to the original condition at 5% B for 4 min before the next injection. The injection volume was 2 µL. The sample extracts were scanned at a UV wavelength ranging from 200 to 400 nm, and the absorbance value of citral at 233 nm (maxima absorbance) was extracted for data analysis using Chromeleon CDS ver 7.2 software (Thermo Fisher Scientific, Brisbane, QLD, Australia). External calibration curves of citral standard, consisting of 2 isomers: neral and geranial, were prepared in methanol at different concentrations ranging from 21.49 to 1074.5 mg/L). The linear equations obtained for the first peak assigned to neral citral (y = 0.2309x -0.5152, r 2 = 0.9986) and the second peak, geranial citral (y = 0.1872x -0.5809, r 2 = 0.9987) were used to quantify the level of neral citral and geranial citral in the sample extracts, respectively. In addition, the total citral level of the extracts was also calculated as the sum of the amount of neral and geranial.

The minimal inhibitory concentration (MIC) was determined as the lowest concentration of citral (3,7-dimethyl-2,6-octadienal, geranial and neral mixture), (Sigma Aldrich, St. Louis, MO, USA), inhibiting visible growth of the tested microorganism. citral stock solution was first prepared with a concentration of 40 μL/mL. Stock solution was then diluted with sterile water and 1% DMSO, giving a succession of concentrations ranging from 0.078 to 20 μL/mL [17 (link)]. Overnight culture of the wild-type yeast S. cerevisiae Σ1278b was used to prepare the microbial inoculation used for the test, reaching an OD of 0.2. Aliquots of 100 μL of diluted inoculation at desired cell concentration were added to each well in the 96-well micro-dilution polystyrene plate, which already contained 100 μL of the citral dilution. The plates were then incubated at 30 °C for 24 h. DMSO alone (at 1% concentration) and sterile water was used as positive control. Each experiment was repeated twice. The preculture and dilutions of the parental strain were prepared with an inoculum solution of YEPD (2% bacto-peptone, 1% yeast extract, and 2% glucose) reaching an OD of circa 0.2 (about 150 μL of the preculture for 10 mL of the prepared medium) in YEPD at 30 °C for 24 h.
