LAB and yeasts were subjected to biochemical characterization with API 50 CHL and API 20C AUX, respectively. Molecular identification was conducted using 16S rRNA gene sequencing, ITS 4 & 5 for DNA amplification, polymerase chain reaction, gel electrophoresis, and Sanger sequencing. The technological qualities of the identified LAB and yeasts were assessed using established protocols.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The API-based characterization of the nonpathogenic organisms revealed that the LAB mainly comprised <i>Lactobacillus<\/i> and <i>Lactococcus<\/i> genera, while <i>Candid<\/i>a, <i>Cryptococcus<\/i>, and <i>Trichosporon<\/i> were the prominent yeast genera. However, the results for molecular identification and percentage of occurrence showed that the LAB involved in the fermentation process mainly included <i>Lactobacillus<\/i> (70%) and <i>Lactococcus<\/i> (30%), while <i>Candida<\/i> (40%), <i>Cryptococcus<\/i> (35%), <i>Derbaryomyces<\/i> (10%), <i>Trichomonascus<\/i> (10%), and <i>Naganishia<\/i> (5%) were the main yeast genera. Additionally, <i>Trichomonascus ciferri<\/i> was identified as a novel organism isolated from ogi. Highest concentrations of lactic acid, hydrogen peroxide, and diacetyl were recorded in ogi containing <i>Lactobacillus delbrueckii<\/i> RSL11 and <i>Lactobacillus<\/i> sp. MLL5, with values of 30.0 \u00b1 0.01 mg\/g, 38.0 \u00b1 0.00 g\/l, and 46.0 \u00b1 0.001 g\/l, respectively.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Taken together, LAB and yeasts are important microorganisms with technological potentials for use as starter cultures in food fermentation processes for producing safe and functional foods.<\/jats:p>\n <\/jats:sec>","DOI":"10.5114\/bta\/214383","type":"journal-article","created":{"date-parts":[[2026,4,1]],"date-time":"2026-04-01T06:49:27Z","timestamp":1775026167000},"page":"45-56","source":"Crossref","is-referenced-by-count":2,"title":["Biochemical and molecular identification of lactic acid bacteria and yeasts with technological qualities from <i>ogi<\/i> (a cereal-based fermented food in Nigeria)"],"prefix":"10.5114","volume":"107","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0047-8242","authenticated-orcid":false,"given":"Praise Temilade","family":"Ozabor","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taiwo Samson","family":"Olumakinde","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timilehin Emmanuel","family":"Oluokun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5434-1359","authenticated-orcid":false,"given":"Johnson Olaleye","family":"Oladele","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8401-7728","authenticated-orcid":false,"given":"Ilesanmi Festus","family":"Fadahunsi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3061","published-online":{"date-parts":[[2026,4,1]]},"reference":[{"key":"ref-1741749","doi-asserted-by":"publisher","DOI":"10.3390\/molecules25040927"},{"key":"ref-1741750","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodcont.2019.106963"},{"key":"ref-1741751","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/721067"},{"key":"ref-1741752","doi-asserted-by":"publisher","DOI":"10.1007\/s12602-022-10022-w"},{"key":"ref-1741753","doi-asserted-by":"publisher","DOI":"10.1007\/s00284-019-01788-4"},{"key":"ref-1741754","doi-asserted-by":"publisher","DOI":"10.9734\/jamb\/2021\/v21i930379"},{"key":"ref-1741755","doi-asserted-by":"publisher","DOI":"10.2174\/1874070701711010094"},{"key":"ref-1741756","doi-asserted-by":"publisher","DOI":"10.1007\/s13197-022-05493-2"},{"key":"ref-1741757","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodcont.2015.09.037"},{"key":"ref-1741758","doi-asserted-by":"publisher","DOI":"10.3329\/bjsir.v54i2.41668"},{"key":"ref-1741759","doi-asserted-by":"publisher","DOI":"10.1016\/j.nfs.2022.03.001"},{"key":"ref-1741760","doi-asserted-by":"publisher","DOI":"10.1080\/08905436.2021.1940197"},{"key":"ref-1741761","doi-asserted-by":"publisher","DOI":"10.1007\/s13197-020-04377-7"},{"key":"ref-1741762","doi-asserted-by":"publisher","DOI":"10.1007\/s10482-018-1192-8"},{"key":"ref-1741763","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodchem.2022.132889"},{"key":"ref-1741764","doi-asserted-by":"publisher","DOI":"10.34302\/crpjfst\/2020.12.5.8"},{"key":"ref-1741765","doi-asserted-by":"publisher","DOI":"10.1186\/s42269-020-00482-x"},{"key":"ref-1741766","doi-asserted-by":"publisher","DOI":"10.9734\/JABB\/2017\/33175"},{"key":"ref-1741767","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijfoodmicro.2018.09.001"},{"key":"ref-1741768","doi-asserted-by":"publisher","DOI":"10.1080\/87559129.2016.1196491"},{"key":"ref-1741769","doi-asserted-by":"publisher","DOI":"10.1039\/d1fo00290b"},{"key":"ref-1741770","doi-asserted-by":"publisher","DOI":"10.5851\/kosfa.2022.e56"},{"key":"ref-1741771","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2019.01789"},{"key":"ref-1741772","doi-asserted-by":"publisher","DOI":"10.1007\/s00203-021-02222-9"},{"key":"ref-1741773","doi-asserted-by":"publisher","DOI":"10.3390\/agriculture11040358"},{"key":"ref-1741774","doi-asserted-by":"publisher","DOI":"10.1016\/j.copbio.2016.11.010"},{"key":"ref-1741775","doi-asserted-by":"publisher","DOI":"10.1155\/2022\/4419955"},{"key":"ref-1741776","doi-asserted-by":"publisher","DOI":"10.3390\/beverages4020036"},{"key":"ref-1741777","doi-asserted-by":"publisher","DOI":"10.1016\/j.jff.2023.105666"},{"key":"ref-1741778","doi-asserted-by":"publisher","DOI":"10.5897\/JABSD2019.0365"},{"key":"ref-1741779","doi-asserted-by":"publisher","DOI":"10.1016\/j.lwt.2019.108769"},{"key":"ref-1741780","unstructured":"Onipede GO, Odah BC, Kolapo AL, Ajayi AA, Fawole AO. 2021.
