An S-layer (surface layer) is a cell surface protein layer found in many different bacteria and in some archaea, where it serves as the cell wall. All S-layers are made up of a two-dimensional array of proteins and have a crystalline appearance, the symmetry of which differs between species.
[2] [3] [4] Coccus refers to the shape of the bacteria and can contain multiple genera, such as staphylococci or streptococci. Cocci can grow in pairs, chains, or clusters, depending on their orientation and attachment during cell division. In contrast to many bacilli-shaped bacteria, most cocci bacteria do not have flagella and are non-motile. [5]
The first report of minicells in the scientific literature dates to 1930., [3] but the first use of the name "minicell" dates to 1967 [2] Minicells of a variety of gram negative [4] and gram positive [5] [6] bacteria, including Escherichia coli [7] and Salmonella enterica, [8] have been reported, but in principle, minicells could be generated for any bacterial species that can be genetically ...
Human microbiota are microorganisms (bacteria, viruses, fungi and archaea) found in a specific environment. They can be found in the stomach, intestines, skin, genitals and other parts of the body. [1] Various body parts have diverse microorganisms. Some microbes are specific to certain body parts and others are associated with many microbiomes.
Collected and stored sediment samples were found to have surviving T. namibiensis cells after over two years. [3] The cells had no access to any added sulfide or nitrate during this time. In the surviving cells, there was a notable size decrease. [3] To survive without growing the cells depended on the nutrient stores of the central vacuoles.

The Pelagibacterales are an order in the Alphaproteobacteria composed of free-living marine bacteria that make up roughly one in three cells at the ocean's surface. [2] [3] [4] Overall, members of the Pelagibacterales are estimated to make up between a quarter and a half of all prokaryotic cells in the ocean.
