Hyphomicrobiales
The ''Hyphomicrobiales'' are an order of Gram-negative Alphaproteobacteria. The rhizobia, which fix nitrogen and are symbiotic with plant roots, appear in several different families. The four families ''Nitrobacteraceae'', ''Hyphomicrobiaceae'', '' Phyllobacteriaceae'', and ''Rhizobiaceae'' contain at least several genera of nitrogen-fixing, legume-nodulating, microsymbiotic bacteria. Examples are the genera ''Bradyrhizobium'' and ''Rhizobium''. Species of the ''Methylocystaceae'' are methanotrophs; they use methanol (CH3OH) or methane (CH4) as their sole energy and carbon sources. Other important genera are the human pathogens ''Bartonella'' and ''Brucella'', as well as ''Agrobacterium'' (useful in genetic engineering).

Pedomicrobium
Pedomicrobium is a ubiquitous bacterium dominant in biofilms of man-made aquatic environments such as water distribution systems and bioreactors. Due to their abilities to oxidise manganese (Mn), they are found to be the main culprits of Mn related “dirty water” (Sly et al., 1988a). Taxonomy and ecology of pedomicrobium Taxonomy Based on 16S rRNA sequence analysis, ''Pedomicrobium'' is a bacterium that belongs to the family Hyphomicrobiaceae, within the order of Hyphomicrobiales The ''Hyphomicrobiales'' are an order of Gram-negative Alphaproteobacteria. The rhizobia, which fix nitrogen and are symbiotic with plant roots, appear in several different families. The four families ''Nitrobacteraceae'', ''Hyphomicrobiaceae' ... under the class of Alphaproteobacteria, in the phylum Pseudomonadota (Garrity et al., 2001). There are twenty genera in the family Hyphomicrobiaceae (Williams et al., 1990), of which ''Pedomicrobium'' is most closely related to ''Hyphomicrobium'' and ...

Hyphomicrobium
''Hyphomicrobium'' is a genus of Gram-negative, non-spore-forming, rod-shaped bacteria from the family of Hyphomicrobiaceae. It has a large polar or sub-polar filiform prostheca very similar to that of ''Caulobacter''. In addition to having a nutritional function, the prostheca also plays a role in the initiation of DNA replication. Reproduction in ''Hyphomicrobium'' begins when its hyphal filament (prostheca) grows from one end of the cell (this happens when the cell no longer has a flagellum) and the bud grows from the tip of the prostheca that eventually differentiates into a new swarmer cell.

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 ( Rhodospirillaceae). 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. Taxonomy Purple bacteria belong to phylum of ''Pseudomonadota''. This phylum was established by Carl Woese in 1987 calling it "purple bacteria and their relatives" even if this is not appropriate because most of them are not purple or photosynthetic. Purple bacteria are distributed between 3 classes:''Alphaproteobacteria'', ''Betap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hypha
A hypha (; ) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Structure A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells. The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have aseptate hyphae, meaning their hyphae are not partitioned by septa. Hyphae have an average diameter of 4–6 µm. Growth Hyphae grow at their tips. During tip growth, cell walls are extended by the external assembly and polymerization of cell wall components, and the internal production of new cell membrane. The S ...
