The amino acid sequence of the peptide moiety of the mureins of Lactobacillus coryniformis and Lactobacillus cellobiosus cell walls was determined. This was accomplished by the identification of peptides obtained after partial hydrolysis of purified cell walls and by the identification of UDP-activated murein precursors accumulated by ᴅ-cycloserine inhibition. The amino acid sequence proved to be : ʟ-ala-ᴅ-glu-ʟ-lys-ᴅ-ala for L. coryniformis and L-ala-D-glu-L-orn-D-ala for L. cellobio-.D-asp D-aspsus. Aspartic acid is involved in the cross-linking of the mureins by forming a peptide bond with the C-terminal D-alanine of an adjacent muropeptide. Glutamic acid as well as aspartic acid are present as amides.

Abstract Objectives The objective of this study was to analyze the TDF, soluble and insoluble fibers, comparing the results with the new analytical method and for minerals associated with fiber. This is the first reporting of date fibers comparing the methods of analysis. Methods TDF methods AOAC 2011.25 methods were updated using Rapid Integrated (RI), a rapid digestion of 4 hours closely resembling human digestion. Testing was conducted at Medallion in Minneapolis, Minnesota. Equal part deglet noor and medjool varieties were analyzed by both methods. Minerals were tested by ICP Mass Spec Eurofin, Wisconsin. Results TDF for the new RI method yielded higher results than AOAC 2011.25 (8.7 mg vs 8.0 mg/100 g). Both soluble and insoluble are considered bioavailable, as they interact with the gut intestinal epithelial and intestinal microflora in the digestive process. Most of date TDF are insoluble 64% and 34% are soluble. The 0.7 mg increase in TDF comes mostly as Soluble. The new RI method and the AOAC 2011.25 Soluble were (3.1 vs 2.5 mg/100 g) respectively. The Insoluble Dietary Fibers showed a slight increase of (0.1 mg/100 g) with the new method at (5.6 vs 5.5 mg/100 g.) Calcium (62.5 mg/100 grams.) indicates cell wall pectin cross-linking. Selenium was (4.94 mg/100 g) and upregulates genes involved in building cell walls. Boron was (0.942 mg/100 g) which is involved with the elongation factor for cell walls. Conclusions The new increased values of date Dietary Fibers and minerals linked to fiber show dates as a positive inclusion in diets. Dates have been shown to have many health benefits including decrease the risk of colon cancer. Funding Sources California Date Commission, Indio, California, provided an unrestricted grant to fund this research.
