Following fixation in 4% PFA, samples were embedded in 1% agarose by boiling and slowly cooling down to room temperature. Samples processed with BABB were sequentially incubated in 25, 50, 80, and 100% ethanol (Merck Millipore, Burlington, MA, United States) for 8 h each at room temperature. Samples processed with 1-propanol BABB (1P-BABB) were sequentially incubated in 25, 50, 80, and 100% 1-propanol (Merck Millipore, Burlington, MA, United States) for 8 h each at room temperature. Samples processed with tert-butanol BABB (tB-BABB) were sequentially incubated in 25, 50, 80, and 100% tert-butanol (Daejung Chemical & Metals Co. Ltd., Gyeonggi-do, Korea) for 8 h each at room temperature. After alcohol dehydration, the samples were incubated in fresh solutions of either 100% ethanol, 1-propanol, or tert-butanol, as appropriate, for 12 h at room temperature. Subsequently, samples were incubated in dichloromethane (DCM; Sigma-Aldrich Inc., St. Louis, MO, United States) for 1 h at room temperature. Samples were then incubated in BABB solution [1 volume of benzyl alcohol (BA; Sigma-Aldrich Inc., St. Louis, MO, United States) to 2 volumes of benzyl benzoate (BB; Duksan Pure Chemicals, Gyeonggi-do, Korea)] for 1–2 days until they achieved optical transparency.

Heat Treatment in Resistometer with Benzyl Alcohol

Heat treatments were carried out in a specially designed resistometer (Condón et al., 1993) . Briefly, this instrument consists in a 350-mL vessel provided with an electrical heater for thermostation, an agitation device to ensure inoculum distribution and temperature homogeneity, and ports for the injection of microbial suspension and for the extraction of samples. Once treatment temperature had attained stability (±0.1 °C), 0.2 mL of an appropriately diluted cell suspension was injected into the main chamber containing the treatment media. After inoculation, samples were collected at different treatment times and immediately pour-plated (Condón et al., 1996) . The treatment medium was McIlvaine citrate-phosphate buffer of pH 7.0 (Dawson et al., 1974) .
In some experiments, benzyl alcohol (BA) (Sigma, St. Louis, USA) was added as a membrane fluidizer to the cell suspensions and to the treatment medium at concentrations ranging from 5 mM to 20 mM (Cebrián et al., 2016; Shigapova et al., 2005) .

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
