Pseudonocardia Asaccharolytica
''Pseudonocardia asaccharolytica'' is a dimethyl disulfide-degrading actinomycete The Actinomycetales is an order of Actinomycetota. A member of the order is often called an actinomycete. Actinomycetales are generally gram-positive and anaerobic and have mycelia in a filamentous and branching growth pattern. Some actinomycete ..., with type strain DSM 44247T.

Dimethyl Disulfide
Dimethyl disulfide (DMDS) is an organic chemical compound with the molecular formula which is the simplest disulfide. It is a flammable liquid with an unpleasant, garlic-like odor. Occurrence Dimethyl disulfide is a widespread natural odoriferous compound emitted from many sources such as bacteria, fungi, plants and animals. It is an oxidation product of methanethiol in air. Along with dimethyl sulfide and dimethyl trisulfide it has been confirmed as volatile compounds given off by the fly-attracting plant known as dead-horse arum ('' Helicodiceros muscivorus''). These flies are attracted to the odor resembling that of fetid meat, and thus help pollinate this plant. DMDS can be produced by the oxidation of methanethiol, e.g. with iodine: : Chemical reactions Important reactions include chlorination giving methanesulfenyl chloride (), methanesulfinyl chloride (), and methanesulfonyl chloride () as well as oxidation with hydrogen peroxide or peracetic acid giving the thiosulf ...

Actinomycete
The Actinomycetales is an order of Actinomycetota. A member of the order is often called an actinomycete. Actinomycetales are generally gram-positive and anaerobic and have mycelia in a filamentous and branching growth pattern. Some actinomycetes can form rod- or coccoid-shaped forms, while others can form spores on aerial hyphae. Actinomycetales bacteria can be infected by bacteriophages, which are called actinophages. Actinomycetales can range from harmless bacteria to pathogens with resistance to antibiotics. Reproduction Actinomycetales have 2 main forms of reproduction: spore formation and hyphae fragmentation. During reproduction, Actinomycetales can form conidiophores, sporangiospores, and oidiospores. In reproducing through hyphae fragmentation, the hyphae formed by Actinomycetales can be a fifth to half the size of fungal hyphae, and bear long spore chains. Presence and associations Actinomycetales can be found mostly in soil and decaying organic matter, as well as in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudonocardia
''Pseudonocardia'' is the type genus of the bacteria family Pseudonocardiaceae. Members of this genus have been found living mutualistically on the cuticle of the leafcutter ants because the bacteria has antibiotic properties that protect the fungus grown by the ants. When they are grooming, their legs are passed over their mouth gland (metapleural gland) that produces the antibiotic and then their legs touch the fungi while they are walking around. The ants have metapleural glands that produce the antimicrobial components to eliminate the ''Escovopsis'' fungi. The bacteria may also be found in crypts on the propleural plate. ''Pseudonocardia'' is found to have antibiotic properties provided to the leaf-cutter ant to inhibit the growth of ''Escovopsis'', which is a black yeast that parasitizes the leaf-cutter ant. ''Pseudonocardia'' can be found in both aquatic (including marine) and terrestrial ecosystems. ''Pseudonocardia'' belongs to the phylum ''Actinobacteria.'' Most ''Actinob ...
