Chapter 23.4, Problem 3CC
Summary Introduction
A group of bacteria which derives energy from the sunlight for growth is called as phototrophic bacteria. Their carbon source is coming from organic carbon or carbon dioxide. Oxygenic and anoxygenic phototrophic bacteria are the two types of phototrophic bacteria. Sunlight is the source of energy for oxygenic phototrophic bacteria and it is aerobic. Anoxygenic phototrophic bacteria also use light as the energy source but it is anaerobic and Gram-negative.

The common name for species like Anabena is blue-green algae. This group of bacteria are capable of photosynthesizing. Do they contain chloroplasts? Explain.
Why might chemosynthetic communities exist only in places like the deep-ocean floor rather than across a wide range of land and sea habitats, the way photosynthesis-based communities are?
Consider the diversity of oxygenic and anoxygenic photosynthesis in bacteria:
a. Which group(s) of bacteria carry out oxygenic photosynthesis?
b. Which group(s) of bacteria carry out anoxygenic photosynthesis?

- Compare photo litho autotrophy with chemo-organo heterotrophy. Sun light is the ultimate source of energy and all living organisms obtain their energy directly or indirectly from the sun. However in deep-sea vents (where there is no sun light) life has originated and the many groups of microorganisms are flourishing in such environment. How? Explain your reasoningarrow_forwardThe genus Ferroplasma consists of a few species of acid-loving archaea. One species, F. acidarmanus, was discovered to be the main component of slime streamers (a type of biofilm) deep inside an abandoned California copper mine (Figure 4.11A). F. acidarmanus cells use an ancient energy-harvesting pathway that combines oxygen with ironsulfur compounds in minerals such as pyrite. This reaction dissolves the minerals, so groundwater that seeps into the mine ends up with extremely high concentrations of metal ions such as copper, zinc, cadmium, and arsenic. The reaction also produces sulfuric acid, which lowers the pH of the water around the cells to zero. Despite living in an environment with a composition similar to hot battery acid, F. acidarmanus cells maintain their internal pH at a cozy 5.0. Thus, researchers investigating Ferroplasma metabolic enzymes were surprised to discover that most of the cells enzymes function best at very low pH (Figure 4.11B). A. Deep inside one of the most toxic sites in the United States: Iron Mountain Mine, in California. The water in this stream, which is about 1 meter (3 feet) wide in this photo, is hot (around 40C, or 104F), heavily laden with arsenic and other toxic metals, and has a pH of zero. Slime streamers growing in it are a biofilm dominated by a species of archaea, Ferroplasma acidarmanus. B. pH profiles of four enzymes isolated from F. acidarmus.
