  • Fermented Foods
    Chapter 6 Fermented Foods Fermentation in food processing is the process of converting carbohydrate to alcohol or organic acids using microorganisms, yeasts or bacteria-under anaerobic conditions. Fermented foods are rich in probiotic bacteria so by consuming fermented foods the health of gut microbiome and digestive system can increase and also can enhances the immune system. Sauerkraut Sauerkraut is a finely cut raw cabbage that has been fermented by lactic acid bacteria. It is made by a process of pickling called lactic acid fermentation. The cabbage is finely shredded, layered with salt and left to ferment. Fully cured sauerkraut keeps for several months in an airtight container stored at 150C or below. The fermentation process involves three phases. In the first phase, anaerobic bacteria such as Klebsiella and Enterobacter lead the fermentation and beginning to produce an acidic environment that favors later bacteria. The second phase starks as the acid levels becomes too high for many bacteria and Leuconostoc mesenteroides and other Leuconostoc spp. take dominance. In the third phase, various Lactobacillus species including L. brevis and L. plantarum ferment any remaining sugars, further lowering the pH. Properly cured sauerkraut is sufficiently acidic to prevent a favorable environment for the growth of Clostridium botulinum, the toxins of which cause botulism. Tempeh Tempeh is a traditional Indonesian Soy product made from fermented Soybeans. The principal step in making tempeh is the fermentation of soybeans which undergo inoculation with Rhizopus spp. mold Rhizopus oligosporus. The beans are spread into a thin layer and are allowed to ferment for 24-36 hours at a temperature around 300C.

We found that genomes within the LGC could be divided into 239 de novo species that were discontinuous and exclusive. Comparison of these de novo species to published species led to the identification of nine sets of published species that can be merged and one species that can be split.

Gänzle9,13,*,† and Sarah Lebeer2† Abstract The genus Lactobacillus comprises 261 species (at March 2020) that are extremely diverse at phenotypic, ecological and gen- otypic levels. This study evaluated the taxonomy of Lactobacillaceae and Leuconostocaceae on the basis of whole genome sequences. Parameters that were evaluated included core genome phylogeny, (conserved) pairwise average amino acid identity, clade- specific signature genes, physiological criteria and the ecology of the organisms. Based on this polyphasic approach, we propose reclassification of the genus Lactobacillus into 25 genera including the emended genus Lactobacillus, which includes host- adapted organisms that have been referred to as the Lactobacillus delbrueckii group, Paralactobacillus and 23 novel genera for which the names Holzapfelia, Amylolactobacillus, Bombilactobacillus, Companilactobacillus, Lapidilactobacillus, Agrilactobacil- lus, Schleiferilactobacillus, Loigolactobacilus, Lacticaseibacillus, Latilactobacillus, Dellaglioa,

Here, we developed a detection method for verifying the presence of the kimchi starter Leuconostoc mesenteroides WiKim33, which is used for control of kimchi fermentation. A primer set for multiplex polymerase chain reaction was designed based on the nucleotide sequence of the plasmids in strain WiKim33, and their specificity was validated against 45 different strains of Leuconostoc spp. and 30 other strains. Furthermore, the starter strain consistently tested positive, regardless of the presence of other bacterial species in starter kimchi during the fermentation period. Our findings showed that application of a strain-specific primer set for strain WiKim33 presented a rapid, sensitive, and specific method for detection of this kimchi starter strain during natural kimchi fermentation. Key Words: Leuconostoc mesenteroides WiKim33, strain-specific primers, kimchi starter, multiplex polymerase chain reaction I. Introduction maintenance. The majority of bacteria in kimchi can be cultured (Kim and Chun 2005); therefore, agar-plate Kimchi is fermented by lactic acid bacteria (LAB) at low culturing is typically used as a culture-dependent method for temperatures, ensuring proper ripening and preservation.
