1. Purple bacteria

   Purple bacteria or purple photosynthetic bacteria are Gram-negative proteobacteria that are phototrophic, capable of producing their own food via photosynthesis. They are pigmented with bacteriochlorophyll a or b, together with various carotenoids, which give them colours ranging between purple, red, brown, and orange. They may be divided into two groups – purple sulfur bacteria (Chromatiales, in part) and purple non-sulfur bacteria. Purple bacteria are anoxygenic phototrophs widely spread in nature, but especially in aquatic environments, where there are anoxic conditions that favor the synthesis of their pigments.

1. purple bacteria

   Purple bacteria, also known as purple phototrophic bacteria, are a type of bacteria that are capable of photosynthesis. They are commonly found in aquatic environments, especially in areas that are low in oxygen. They are named after their often purple pigmentation, which originates from pigments in their photosynthetic membranes. These pigments, mainly bacteriochlorophylls and carotenoids, allow the bacteria to harvest energy from sunlight. There are two main types of purple bacteria: purple sulfur bacteria, which produce sulfur as a byproduct of photosynthesis, and purple nonsulfur bacteria, which usually use organic molecules as an electron source for photosynthesis.

Examples of purple bacteria in a Sentence

1. Jennifer Glass:

   However, in the deep past, before oxygen accumulated in the atmosphere, these purple bacteria might have proliferated to such an extent that they could have been detectable on the Earth's surface.

2. Jennifer Glass:

   The big question, and a topic of active scientific debate, is whether the purple bacteria living on the ancient Earth had the ability to protect themselves from UV radiation well enough to inhabit vast expanses of the land surface, like plants do on the modern Earth, the spectral signature of the pigment would be much stronger if the pigmented bacteria covered the land surface.
