are known to proliferate in cucumber juice, deriving energy from the fermentation of sugars to organic acids and ethanol, and theoretically generating carbon dioxide (CO). We hypothesized that the CO produced by the indigenous in the early stage of cucumber fermentation accumulates in the fermenting fruits causing bloater defect. The ability of seven , indigenous to cucumber, to grow and produce CO in cucumber juice medium (CJM), a sterile model system for cucumber fermentation, was characterized.

Article Synopsis
  • This study examined how well ɣ-proteobacteria from fresh cucumbers can grow in cucumber juice and during fermentation, suggesting that while they thrive in juice, fermentation poses challenges.
  • The research found that ɣ-proteobacteria had a higher growth rate in cucumber juice compared to certain lactobacilli, but their growth was heavily inhibited in fermentation with specific salt brines and acid produced by lactobacilli.
  • Overall, the findings indicate that factors like the presence of lactobacilli and the brine composition play crucial roles in the safety and quality of fermented cucumbers, underscoring the complex interactions between various bacteria in food fermentation.

Fermentation of eight vegetables was studied as an alternative for reclamation of surplus volumes. Fermentation performance was predicted by comparing the amounts of acid that could be produced from the intrinsic sugar content with that buffered by the fresh vegetable matrices prior to reaching an inhibitory pH for fermentative microbes (3.30).

The Lactobacillus plantarum and Lactobacillus pentosus genotypes existing in industrial-scale cucumber fermentations were defined using rep-PCR-(GTG)5. The ability of each genotype to ferment cucumbers under various conditions was evaluated. Rep-PCR-(GTG)5 was the technique capable of illustrating the most intraspecies discrimination compared to the sequencing of housekeeping genes (recA, dnaK, pheS and rpoA), MLST and RAPD with primers LP1, OPL5, M14 and COC.

Synopsis of recent research by authors named "Christian Pagan-Medina"

  • - Christian Pagan-Medina's research primarily focuses on the fermentation processes of cucumbers, exploring the microbial interactions and biochemical dynamics that contribute to product quality and safety during fermentation.
  • - Recent findings indicate that certain indigenous microorganisms, particularly ɣ-Proteobacteria and Lactobacilli, play critical roles in cucumber fermentation, influencing factors such as CO production and growth inhibition in low salt environments.
  • - The author has also investigated alternative methods for food waste reclamation through vegetable fermentation, assessing how intrinsic sugar content and composition impact fermentation performance and microbial activity.
