Despite their unusually small cell size it is common to find more than one type of virus attached to the cells while in the biofilms. Furthermore, the cells contain on average ≈92 ribosomes per cell, whereas the average E. coli cell grown in culture contains ≈10,000 ribosomes. This suggests that for ARMAN cells a much more limited number of ...
Its cells are only 400 nm in diameter, making it the smallest known living organism, and the smallest known archaeon. N. equitans ' genome consists of a single circular chromosome , and has an average GC-content of 31.6%.
Adult males of the parasitic wasp Dicopomorpha echmepterygis can be as small as 139 μm (0.139 mm) long, smaller than some species of protozoa (single-cell creatures); females are 40% larger. [30] Megaphragma caribea from Guadeloupe , measuring 170 μm (0.17 mm) long, is another contender for smallest known insect in the world.
Structures found on meteorite fragment Allan Hills 84001. Nanobacterium (/ ˌ n æ n oʊ b æ k ˈ t ɪər i əm / NAN-oh-bak-TEER-ee-əm, pl. nanobacteria / ˌ n æ n oʊ b æ k ˈ t ɪər i ə / NAN-oh-bak-TEER-ee-ə) is the unit or member name of a former proposed class of living organisms, specifically cell-walled microorganisms, now discredited, with a size much smaller than the generally ...
Any acid with a value which is less than about -2 behaves as a strong acid. This results from the very high buffer capacity of solutions with a pH value of 1 or less and is known as the leveling effect. [3] The following are strong acids in aqueous and dimethyl sulfoxide solution.
Simple organic acids like formic or acetic acids are used for oil and gas well stimulation treatments. These organic acids are much less reactive with metals than are strong mineral acids like hydrochloric acid (HCl) or mixtures of HCl and hydrofluoric acid (HF). For this reason, organic acids are used at high temperatures or when long contact ...
The genus contains the smallest known free-living eukaryotic species, with an average size of 0.8 μm. [1] The ultrastructure of cells in this genus have so far been characterised by remarkable simplicity, being coccoid cells lacking a cell wall and containing a single chloroplast, a single mitochondrion, and a single Golgi body as well as its nucleus.

It is a living organism (contains DNA or some analogue, and reproduces).; Has a morphology similar to Actinomycetes and fungi.; Nanobes are about 20 nm in diameter, which may be too small to contain the basic elements for an organism to exist (DNA, ribosomes, etc.), suggesting that if they grow and reproduce they would need to do so in an unconventional way.
