Photoautotrophic organisms

Photoautotrophic organisms, such as algae, cyanobacteria, and plants, all contain chlorophyll a and obtain energy by a process known as oxygenic photosynthesis. The overall chemical reaction of this process is ...

Another group of compounds well suited for CSIA because of their widespread occurrence are plant pigments (Bidigare et al., 1991 Kennicutt et al., 1992). Chorophylls and carotenoids are involved in photoautotrophic reactions that produce organic matter and can provide information on the nutritional and light conditions of algae (Welschmeyer and Lorenzen, 1985 Jeffrey et al., 1997). In fact, recent work has shown that a 5.1%o... 

Autotrophic microorganisms synthesize organic substances from carbon dioxide through a process known as carbon dioxide fixation. They are important in nature because carbon dioxide fixation works as a precursor for the organic substrates that form the basis of the food chain for other organisms. Autotrophic bacteria include those that obtain their energy from light (photoautotrophs) and those that obtain it from the oxidation of chemical bonds (chemoau-totrophs). 

It can be directly derived from the rule of three functions (see below. Section 2.2.7) that three substrates (it might suffice that these are different enantiomers or diastereomers) correspond to three enzymes which can be distinguished in both functional and chemical terms. For each essential element, there thus must be at least four substances (three solid or dispersed/membrane-attached enzymes and the very speciation form of the essential element in dissolved or atmospheric (N, O, C, H, S) states) in the organism or directly linked to it in the enviromnent (soil, water, food, for photoautotrophs also the atmosphere (CO )). Living beings share one more property with traditional multiphase systems the...
