Microbiol."],"abstract":"<jats:p>\n                    Lactic acid bacteria are increasingly becoming important dietary supplements due to their health benefits when consumed in adequate quantity. The increasing attention on these important microbes has necessitated an in-depth understanding of their physiological processes, such as nutritional requirements and growth patterns, to better harness their probiotic potentials. This study was carried out to determine the nutritional requirements for the growth of\n                    <jats:italic>L. salivarius<\/jats:italic>\n                    ZJ614 and\n                    <jats:italic>L. reuteri<\/jats:italic>\n                    ZJ625 from a chemically defined medium and evaluate growth kinetics by fitting different sigmoidal growth models. The complete CDM contains 49 nutritional ingredients such as glucose, Tween 80\n                    <jats:sup>\u00ae<\/jats:sup>\n                    , mineral salts, buffers, amino acids, vitamins, and nucleotides at defined concentrations. In addition, the minimal nutritional requirements of the isolates were determined in a series of single-omission experiments (SOEs) to compose the MDM. Growth curve data were generated by culturing in an automated 96-well micro-plate reader at 37\u00b0C for 36 h, and photometric readings (optical density: OD\n                    <jats:sub>600<\/jats:sub>\n                    ) were taken. The data were summarized in tables and charts using Microsoft Excel, while growth evaluation was carried out using open-source software (\n                    <jats:italic>Curveball<\/jats:italic>\n                    ) on Python. The results revealed that omission of the amino acids, vitamins, and nucleotides groups resulted in 2.0, 20.17, and 60.24% (for\n                    <jats:italic>L. salivarius<\/jats:italic>\n                    ZJ614) and 0.95, 42.7, and 70.5% (for\n                    <jats:italic>L. reuteri<\/jats:italic>\n                    ZJ625) relative growths, respectively. Elimination of the individual CDM components also indicates varying levels of growth by the strains. The growth curve data revealed LogisticLag2 and Baranyi\u2013Roberts models as the best fits for\n                    <jats:italic>L. reuteri<\/jats:italic>\n                    ZJ625 and\n                    <jats:italic>L. salivarius<\/jats:italic>\n                    ZJ614, respectively. All the strains showed appreciable growth on the CDM and MDM as observed in de Man\u2013Rogosa\u2013Sharpe (MRS) broth. We also described the growth kinetics of\n                    <jats:italic>L. reuteri<\/jats:italic>\n                    ZJ625 and\n                    <jats:italic>L. salivarius<\/jats:italic>\n                    ZJ614 in the CDM, and the best models revealed the estimated growth parameters.\n                  <\/jats:p>","DOI":"10.3389\/fmicb.2022.865493","type":"journal-article","created":{"date-parts":[[2022,5,6]],"date-time":"2022-05-06T03:41:02Z","timestamp":1651808462000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":29,"title":["Formulation of Chemically Defined Media and Growth Evaluation of Ligilactobacillus salivarius ZJ614 and Limosilactobacillus reuteri ZJ625"],"prefix":"10.3389","volume":"13","author":[{"given":"Iliya Dauda","family":"Kwoji","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moses","family":"Okpeku","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew Adekunle","family":"Adeleke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olayinka Ayobami","family":"Aiyegoro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,5,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"5871","DOI":"10.1007\/s00253-014-5641-7","article-title":"Nutritional requirements and media development for Lactococcus lactis IL1403","volume":"98","author":"Aller","year":"2014","journal-title":"Appl.
