''Prosopis africana'' is a flowering plant species in the genus ''Prosopis'' found in Africa. Its common names include African mesquite, iron tree, ''gele'' (Malinke) (traditional djembe wood) or ''somb'' tree. In the Serer creation myth, it is one of the sacred trees that grew not just first, but also within the primordial swamp on Earth. Seeds of ''P. africana'' are used in Nigeria to prepare daddawa, kpaye or okpeye, fermented products used as food condiments. Several species of bacteria especially ''Bacillus subtilis'', ''Bacillus licheniformis'', ''Bacillus megaterium'', ''Staphylococcus epidermidis'' and ''Micrococcus'' spp were found to be the most actively involved organisms in the production of okpiye. Sequencing of 16S rRNA genes of selected strains representative of the major clusters revealed that the Bacillus strains associated with okpehe fermentation were ''B. subtilis'', ''B. amyloliquefaciens'', ''B. cereus'' and ''B. licheniformis'' (in decreasing order of incidence). The presence of enterotoxin genes in all ''B. cereus'' strains was demonstrated by multiplex PCR. The high incidence of detection (20%) of possibly pathogenic ''B. cereus'' strains that contained enterotoxin genes indicated that these fermented foods may constitute a potential health risk. The seeds also produce a gum. The plant produces the alkaloids prosopine and prosopinine. == See also == * List of plants of Burkina Faso * Wildlife of Benin 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「prosopis africana」の詳細全文を読む スポンサード リンク
