Phototropic Bacteria (Noun)
Meaning
Green and purple bacteria; energy for growth is derived from sunlight; carbon is derived from carbon dioxide or organic carbon.
Classification
Nouns denoting animals.
Examples
- The community was comprised primarily of green phototropic bacteria which predominantly utilise far red and infrared wavelengths.
- Anaerobic and some facultative phototropic bacteria thrive in wet environments where sunlight and carbon based substances are readily available.
- Some green phototropic bacteria are known for their intricate surface arrangement of sulfide utilizing membranes which give off vibrant pigmentation.
- Observation of purple phototropic bacteria growing optimally on surface agar infused with organic compounds suggests a marked adaptation to nutrient lacking conditions.
- Their reliance on carbon obtained from dissolving carbon dioxide or by ingestion of organic residues supports hypotheses regarding the origins of photosynthesis in the line of phototropic bacteria ancestors.
