The DNA amplicons were separated on a 5% acrylamide gel and compared with a 1-kb ladder (Gibco-BRL). The G-C content of 37-40% has been reported as standard. Figure S1. Effects of metal ions on glucansucrase‐production of L. mesenteroides DRP105. Sugars and alcohols were analyzed by HPLC by using an Aminex HPX 87-C column (Bio-Rad, Hercules, Calif.) with a differential refractometer detector. Citrate and malate are the two major organic acids metabolized by leuconostocs. DRP2-19 isolated from Chinese Sauerkraut Leuconostoc is a coccus, often lenticular on agar and usually occurs in pairs or chains.

Effects of yeast extract powder concentration on glucansucrase‐production of L. mesenteroides DRP105. Unlike most leuconostocs, L. fallax does not carry out malolactic fermentation. Leuconostoc is nonhemolytic, vancomycin resistant organism. RAPD patterns of the sauerkraut isolates. Hiebert N, Kessel T, Skaljac M, Spohn M, Vilcinskas A, Lee KZ. Lactobacillus casei starter culture improves vitamin content, increases acidity and decreases nitrite concentration during sauerkraut fermentation. They are generally ovoid cocci often forming chains. Any queries (other than missing content) should be directed to the corresponding author for the article. Members of Leuconstoc spp. 16S rDNA sequencing and comparative sequence analysis. ] When BLAST2 did not align sequences over the whole length, BestFit (SeqWeb, version 1.1; Wisconsin Package, version 10; Genetics Computer Group Inc., Madison, Wis.) was used. Therefore, it appears that L. fallax behaves mostly like MDC−L. DNA amplification was performed in a Gradient 96 Robocycler (Stratagene, La Jolla, Calif.) programmed as follows: 10 min at 94°C; 25 cycles of 1 min at 94°C, 5 min at 55°C, and 2 min at 72°C; and 5 min at 72°C. Sensitivity to bacteriophages was determined by spotting 5-μl portions of serial dilutions of phage lysates on a lawn of the host strain (42). Fermentations were rapid, with a more uniform decline in pH when starter culture was added. Enter multiple addresses on separate lines or separate them with commas. 3. Identification of lactic acid bacteria by morphological analysis and biochemical typing is not as reliable or consistent as genotypic characterization (32, 36, 37). These sequences were also compared to that of the L. fallax type strain, and the percentages of homology were calculated by using BLAST2, taking into account the undetermined nucleotides. Effects of peptone concentration on glucansucrase‐production of L. mesenteroides DRP105. Figure S15. The malolactic reaction is defined as decarboxylation of l-malic acid into l-lactic acid and carbon dioxide by the malolactic enzyme (18, 23). Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors. ITS-PCR analysis is a rapid and simple way to identify lactic acid bacterial species in vegetable fermentations (5). Cabbage juice may contain microbial inhibitors (24); therefore, the ability of L. fallax strains to grow in cabbage juice was tested prior to experiments. Experimental design and results of the Plackett‐Burman design, Table S3. of Food Science, NC State Univ., Raleigh, NC 27695‐7624 (E‐mail: breidt@ncsu.edu). Both total 16S rRNA genes and the sequences of the ∼300-bp fragment of the 16S rRNA genes containing variable regions V1 and V2 in Leuconostoc species were compared. Leuconstoc mesenteroides is used primarily in saurkraut production, where its heterofermentative abilities are used in the first stage of four to convert glucose and fructose in cabbage to lactic acid, mannitol, acetic acid, ethanol, and carbon dioxide. Figure S16. Food Sci Biotechnol. The presence and diversity of L. fallax strains recovered suggest that our current understanding of the microbial ecology of sauerkraut fermentation is incomplete. Leuconostoc is a genus of gram-positive bacteria, placed within the family of Leuconostocaceae. Heated cabbage pieces were processed with a Braun Juicer (Braun Company, Kronberg, Germany). Growth in cabbage juice.The initial pH of the cabbage juice ranged from 5.98 to 6.03. Results of the regression analysis of the central composite design, Table S7.  |  A modification of the procedure of Jensen et al. Time course of glucansucrase‐production of L. mesenteroides DRP105. Leuconostoc mesenteroides fermentation produces butyric acid and mediates Ffar2 to regulate blood glucose and insulin in type 1 diabetic mice. Effects of phosphate on glucansucrase‐production of L. mesenteroides DRP105. 2514-2522, F. Breidt Jr. 2004. These include ribotyping, pulsed-field gel electrophoresis, 16S rDNA sequencing, RAPD typing, and phage typing (17, 22, 32, 33, 36, 37, 39, 41). The thermal cycler was programmed as follows: 10 min at 94°C; four cycles of 45 s at 94°C, 2 min at 30°C, and 45 s at 72°C; 36 cycles of 15 s at 94°C, 30 s at 36°C, and 45 s at 72°C; and 10 min at 72°C. Figure S3. Effects of phosphate on glucansucrase‐production of L. mesenteroides DRP105. Figure S5. Our study also suggested that Tween 80 and dextran have potential to improve glucansucrase stability at temperature (30 °C) higher than enzyme storage temperature in crude fermented broth. Kimchi microflora: history, current status, and perspectives for industrial kimchi production. Figure S2. Chemical and Sensory Properties of Sauerkraut Produced with Leuconostoc mesenteroides Starter Cultures of Differing Malolactic Phenotypes SUZANNE D. JOHANNINGSMEIER, HENRY P. FLEMING, R.L. mesenteroides strains for cabbage juice fermentation. Instead, they obtain energy through substrate level phosphorylation, during the fermentation of sugars to lactic acid, ethanol or acetate, and C02. However, the three L. mesenteroides subspecies showed the same patterns (Fig. Based on Plackett–Burman Experiment, sucrose, sodium acetate and initial pH were found to be the most significant factors for glucansucrase production of L. mesenteroidesDRP105. Results of the regression analysis of the Plackett‐Burman gesign, Table S6. This observation is consistent with replacement of the mostly MDC+ species L. mesenteroides by the mostly MDC− species L. fallax. Figure S8. The thermal cycler was programmed as follows: 10 min at 94°C; 25 cycles of 1 min at 94°C, 2 min at 61°C, and 2 min at 72°C; and 5 min at 72°C. DNA samples were sequenced commercially (Davis Sequencing, Davis, Calif.) with a model ABI Prism 277 DNA sequencer (Applied Biosystems, Foster City, Calif.). However, there is little information available regarding the diversity of Leuconostoc species and strains involved in sauerkraut fermentation. and you may need to create a new Wiley Online Library account. The most significant difference between L. fallax and L. mesenteroides was the inability of the former to carry out the malolactic reaction through the malate decarboxylase. Range of different factors studied in the central composite design, Table S4.
