Article Synopsis
- Certain species in the genus are responsible for spoilage in beverages by producing guaiacol, a compound that creates off-aromas, yet there is limited understanding of the genes involved in this process.
- Researchers found that guaiacol-producing species have genes associated with oxidative stress, particularly a gene involved in the synthesis of guaiacol.
- It is important for the food industry to differentiate between species with high spoilage potential and those that do not produce guaiacol, as not doing so can lead to ineffective waste reduction strategies.
Some species of Alicyclobacillus spoil beverages by producing guaiacol. Current culture-based methods detect the presence of Alicyclobacillus spp. and a subsequent peroxidase assay determines if the isolate can produce guaiacol.

Six thermo-acidophilic, spore-forming strains were isolated from a variety of juice products and were characterized genetically and phenotypically. According to 16S rRNA and gene phylogenetic analyses and average nucleotide identity comparisons against the species demarcation cutoff at <95 %, these six strains were determined to represent three novel species of . The isolates were designated FSL-W10-0018, FSL-W10-0037, FSL-W10-0048, VF-FSL-W10-0049, FSL-W10-0057 and FSL-W10-0059.
