Gram-negative
Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. Their defining characteristic is that their cell envelope consists of a thin peptidoglycan cell wall sandwiched between an inner ( cytoplasmic) membrane and an outer membrane. These bacteria are found in all environments that support life on Earth. Within this category, notable species include the model organism '' Escherichia coli'', along with various pathogenic bacteria, such as '' Pseudomonas aeruginosa'', '' Chlamydia trachomatis'', and '' Yersinia pestis''. They pose significant challenges in the medical field due to their outer membrane, which acts as a protective barrier against numerous antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and the antimicrobial enzyme lysozyme produced by animals as part of their innate immune system.

Facultatively Anaerobic
A facultative anaerobic organism is an organism that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation if oxygen is absent. Some examples of facultatively anaerobic bacteria are ''Staphylococcus'' spp., ''Escherichia coli'', ''Salmonella'', ''Listeria'' spp., '' Shewanella oneidensis'' and ''Yersinia pestis''. Certain eukaryotes are also facultative anaerobes, including pupfish, fungi such as ''Saccharomyces cerevisiae'' and many aquatic invertebrates such as nereid polychaetes. It has been observed that in mutants of ''Salmonella typhimurium'' that underwent mutations to be either obligate aerobes or anaerobes, there were varying levels of chromatin-remodeling proteins. The obligate aerobes were later found to have a defective DNA gyrase subunit A gene ('' gyrA''), while obligate anaerobes were defective in topoisomerase I (''topI''). This indicates that topoisomerase I and its associated relaxation of chromosomal DNA is requir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rod-shaped
Bacterial cellular morphologies are the shapes that are characteristic of various types of bacteria and often key to their identification. Their direct examination under a light microscope enables the classification of these bacteria (and archaea). 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)''. Other arrangements include pairs, tetrads, clusters, chains and palisades. Types Coccus A coccus (plural ''cocci'', from the Latin ''coccinus'' (scarlet) and derived from the Greek ''kokkos'' (berry)), is any microorganism (usually bacteria) whose overall shape is spherical or nearly spherical. Coccus refers to the shape of the bacteria and can contain multiple genera, such as s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seonamhaeicola
''Seonamhaeicola'' is a genus of bacteria from the family of Flavobacteriaceae Flavobacteriaceae is a family of rod-shaped gram negative bacteria. The family contains many environmental bacteria, with some species being potential pathogens. History The family of ''Flavobacteriaceae'' was first proposed by Reichenbach in 1 ....

Weihai
Weihai ( zh, t=, p=Wēihǎi), formerly Weihaiwei ( zh, s=, p=Wēihǎiwèi, l=Mighty Sea Fort, first=t), is a prefecture-level city and major seaport city in the easternmost Shandong province of China. It borders Yantai to the west and the Yellow Sea to the east, and is the closest mainland Chinese city to South Korea (specifically, Chengshan to Yeonpyeongdo). Compared with the 2,804,771 people in the 2010 Chinese census, there has been a total increase of 101,777 people over the past decade, an increase of 3.63%, with an average annual growth rate of 0.36%. Weihai's population was 2,906,548 as of the 2020 Chinese census, of whom 1,164,730 lived in the current built-up (''or metro'') area of (Huancui District) even though Wendeng, Shandong, Wendeng district to the south with 563,529 inhabitants is soon being conurbated. There are two county-level cities within Weihai; Rongcheng, Shandong, Rongcheng had a built up area with 714,211 inhabitants, while Rushan, Shandong, Rushan had 464 ...

Flavobacteria
The class Flavobacteriia is composed of a single class of environmental bacteria. It contains the family Flavobacteriaceae, which is the largest family in the phylum Bacteroidota. This class is widely distributed in soil, fresh, and seawater habitats. The name is often spelt Flavobacteria, but was officially named Flavobacteriia in 2012. Flavobacteriia are gram-negative aerobic rods, 2–5 μm long, 0.1–0.5 μm wide, with rounded or tapered ends. They form circular cream to orange coloured colonies on agar, and are typically simple to successfully culture. Flavobacteriia is a chemoorganotroph and are known for their ability to mineralize or degrade dissolved organic matter of high molecular weight and particulate plant material. Flavobacteriia have impacts on both the environment and human society, as they are able to cause diseases in many organisms. They are important in the decomposition of organic matter and pollutants, and are key members in the formation of marin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
