Especially, gut\r\nmicrobes are relevant to human physiological functions and various\r\ndiseases, and are of critical importance in various industrial fields\r\nincluding drug development; for example, Waltera acetigignens<\/i>\r\n(JCM 36210<\/a>), Anaerostipes caccae<\/i> (JCM 13470T<\/sup><\/a>) and Anaerostipes hominis<\/i>\r\n(JCM 32275T<\/sup><\/a>), which have been suggested to form spores, produce\r\nbutyric acid. Therefore, it is expected that they will be further\r\ninvestigated as probiotics in the future. Above-mentioned bacterial\r\nspecies are known to form spores to protect their cells from stresses\r\nsuch as heat and acidity and to become resting forms. Cultivation\r\nrequires stimuli to induce germination, which is known to be difficult\r\ndue to the diversity of germination factors among bacterial species.\r\nTherefore, we introduced a new culture method to induce spore\r\ngermination by sterilizing liquid culture medium from fecal material\r\nand adding it to fecal material.\r\nAs a result, Bacterial species of the genera Anaerobutyricum<\/i>,\r\nRoseburia<\/i>, Ruminococcus<\/i>, and Waltera<\/i> were isolated which are expected\r\nto be probiotics. In addition, a number of bacterial species that are\r\nexpected to be new species were also isolated. The culture method to\r\ninduce spore germination as described above is expected to not only\r\ncontribute to the isolation of bacteria, but also to a better\r\nunderstanding of the original potential of bacteria that cannot be\r\ndemonstrated in a resting forms.\r\n\r\nReferences\r\nSakamoto et al<\/i>. 2024.

Especially, gut microbes are relevant to human physiological functions and various diseases, and are of critical importance in various industrial fields including drug development; for example, Waltera acetigignens (JCM 36210), Anaerostipes caccae (JCM 13470T) and Anaerostipes hominis (JCM 32275T), which have been suggested to form spores, produce butyric acid. Therefore, it is expected that they will be further investigated as probiotics in the future. Above-mentioned bacterial species are known to form spores to protect their cells from stresses such as heat and acidity and to […]<\/p>\n","protected":false},"author":17,"featured_media":0,"parent":3314,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"both","_seopress_redirections_param":"","_seopress_redirections_type":301,"_seopress_analysis_target_kw":"","footnotes":"","_wp_rev_ctl_limit":""},"class_list":["post-5251","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"http:\/\/jcm.brc.riken.jp\/en\/wp-json\/wp\/v2\/pages\/5251","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/jcm.brc.riken.jp\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"http:\/\/jcm.brc.riken.jp\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"http:\/\/jcm.brc.riken.jp\/en\/wp-json\/wp\/v2\/users\/17"}],"replies":[{"embeddable":true,"href":"http:\/\/jcm.brc.riken.jp\/en\/wp-json\/wp\/v2\/comments?post=5251"}],"version-history":[{"count":1,"href":"http:\/\/jcm.brc.riken.jp\/en\/wp-json\/wp\/v2\/pages\/5251\/revisions"}],"predecessor-version":[{"id":5254,"href":"http:\/\/jcm.brc.riken.jp\/en\/wp-json\/wp\/v2\/pages\/5251\/revisions\/5254"}],"up":[{"embeddable":true,"href":"http:\/\/jcm.brc.riken.jp\/en\/wp-json\/wp\/v2\/pages\/3314"}],"wp:attachment":[{"href":"http:\/\/jcm.brc.riken.jp\/en\/wp-json\/wp\/v2\/media?parent=5251"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
