Environmental relevance and physiological role of 3-methylhopanoids in anoxygenic phototrophic bacteria
Abstract/Contents
- Abstract
- This dissertation research seeks to utilize laboratory and field techniques to uncover meaning behind the occurrence of 3-methylhopanoids in an anoxygenic phototroph. I am interested in how the environmental context of a new 3-methylhopanoid source organism isolated from an extreme environment will influence future interpretations of both rock record and modern ecosystems. I chose to study this new lineage of 3-methyhopanoid producers in laboratory cultures (CHAPTER 1), in situ from the environments that this strain was directly isolated from (CHAPTER 2), and in silico through the metagenomic data of other hot springs and an expanding list of environments in which the purple non-sulfur bacteria (PNS) call home (CHAPTER 3). This work indicates that PNS bacteria are potential sources of 3-methylhopanoids and thus should be considered along with methanotrophs, and the more rarely indicated acetic acid bacteria, when interpreting modern and ancient sedimentary biomarker records.
