The four main types are bacteriochlorophyll <i>a</i>, bacteriochlorophyll <i>b</i>, chlorophyll <i>a</i>, and bacteriochlorophyll <i>a</i>. They only differ by a single bond at one position.<br /><br />The chlorophylls are light gatherers or electron transport molecules that have nothing to do with the terminal electron donor (H2O or H2S). <br /><br />Is one of these chlorophylls found only in cyanobacteia?Larry Moranhttps://www.blogger.com/profile/05756598746605455848noreply@blogger.comtag:blogger.com,1999:blog-5460788270738656369.post-91287117252103178002012-03-14T00:25:01.089+08:002012-03-14T00:25:01.089+08:00For my part, I was always told that bacteriochloro...For my part, I was always told that bacteriochlorophyll (while uses hydrogen sulphide rather than water) is not the same substance as chlorophyll.Christopher Taylorhttps://www.blogger.com/profile/11075565866351612441noreply@blogger.comtag:blogger.com,1999:blog-5460788270738656369.post-21824583390343959382012-03-13T22:14:00.630+08:002012-03-13T22:14:00.630+08:00... the distinctiveness of cyanobacteria continues...<i> ... the distinctiveness of cyanobacteria continues to be supported: they are the only bacteria to contain chlorophyll ...</i><br /><br />I was under the impression that <a href="http://en.wikipedia.org/wiki/Heliobacteria" rel="nofollow">heliobacteria</a>, <a href="http://en.wikipedia.org/wiki/Green_sulfur_bacteria" rel="nofollow">green sulfur bacteria</a>, <a href="http://jb.asm.org/content/191/21/6701.abstract" rel="nofollow">green filamentous bacteria</a>, and <a href="http://en.wikipedia.org/wiki/Purple_bacteria" rel="nofollow">purple bacteria</a> all contain chlorophyll (usually bacteriochlorophyll). <br /><br />Am I wrong or are you referring to a specific type of chlorophyll?Larry Moranhttps://www.blogger.com/profile/05756598746605455848noreply@blogger.comtag:blogger.com,1999:blog-5460788270738656369.post-3827380341604034032012-03-13T18:01:00.141+08:002012-03-13T18:01:00.141+08:00I am gratified to catch a glimpse of your blog.
