Generally, the basic morphologies are spheres (coccus) and round-ended cylinders or rod shaped (bacillus). But, there are also other morphologies such as helically twisted cylinders (example Spirochetes), cylinders curved in one plane (selenomonads) and unusual morphologies (the square, flat box-shaped cells of the Archaean genus Haloquadratum ...
A Star Fire, or Indian Fire, is the fire design often depicted as the campfire of the old West. Someone lays six or so logs out like the spokes of a wheel (star-shaped). They start the fire at the "hub," and push each log towards the center as the flames consume the ends. [9]
In Huber's and Stetter's first analysis of the bacteria, they found that A. pyrophilus had an optimum pH of 6.8 but ranged anywhere between 5.4 and 7.5, grew at temperatures ranging from 67 °C to 95 °C with an optimum at 85 °C, and had optimal growth with a NaCl concentration of 3% (range of 1-5%).
Some bacteria, called vibrio, are shaped like slightly curved rods or comma-shaped; others can be spiral-shaped, called spirilla, or tightly coiled, called spirochaetes. A small number of other unusual shapes have been described, such as star-shaped bacteria. [42]
Cyanobacterial morphology refers to the form or shape of cyanobacteria. Cyanobacteria are a large and diverse phylum of bacteria defined by their unique combination of pigments and their ability to perform oxygenic photosynthesis. [2] [3] Cyanobacteria often live in colonial aggregates that can take a multitude of forms. [3]
[4] [5] It is known also as C. difficile, or C. diff (/ s iː d ɪ f /), and is a Gram-positive species of spore-forming bacteria. [6] Clostridioides spp. are anaerobic, motile bacteria, ubiquitous in nature and especially prevalent in soil. Its vegetative cells are rod-shaped, pleomorphic, and occur in pairs or short chains. Under the ...
Billowing flames aside, this cement-based campfire is totally safe to use (even indoors!). It comes without the eye-burning smoke and flying embers, AKA the things we don't love about more ...
Bacillus (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Bacillota, with 266 named species.The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural Bacilli is the name of the class of bacteria to which this genus belongs.
