Micromonosporaceae is a family of bacteria of the class Actinobacteria. They are gram-positive, spore-forming soil organisms that form a true mycelium.
Geobacillus stearothermophilus is a rod-shaped, Gram-positive bacterium and a member of the division Firmicutes. The bacterium is a thermophile and is widely distributed in soil, hot springs, ocean sediment, and is a cause of spoilage in food products. It will grow within a temperature range of 30 to 75 °C. Some strains are capable of oxidizing carbon monoxide aerobically. It is commonly used as a challenge organism for sterilization validation studies and periodic check of sterilization cycles. The biological indicator contains spores of the organism on filter paper inside a vial. After sterilizing, the cap is closed, an ampule of growth medium inside of the vial is crushed and the whole vial is incubated. A color and/or turbidity change indicates the results of the sterilization process; no change indicates that the sterilization conditions were achieved, otherwise the growth of the spores indicates that the sterilization process has not been met. Recently a fluorescent-tagged strain, Rapid Readout(tm), is being used for verifying sterilization, since the visible blue fluorescence appears in about one-tenth the time needed for pH-indicator color change, and an inexpensive light sensor can detect the growing colonies.
The Chloroflexi or Chlorobacteria are a phylum of bacteria containing isolates with a diversity of phenotypes, including members that are aerobic thermophiles, which use oxygen and grow well in high temperatures; anoxygenic phototrophs, which use light for photosynthesis ; and anaerobic halorespirers, which uses halogenated organics as electron acceptors.
Porphyromonas is a Gram-negative, non-spore-forming, obligately anaerobic and non-motile genus from the family of Porphyromonadaceae. This genus has been found to be part of the salivary microbiome. The use of targeted 16S rRNA gene metagenomic sequencing has shown that the genus is well represented in healthy individuals from the Human Microbiome Project.
Desulfosporosinus is a genus of strictly anaerobic, sulfate-reducing bacteria, often found in soil.
Opecoelidae is a family of trematodes. It is the largest digenean family with over 90 genera and nearly 900 species, almost solely found in marine and freshwater teleost fishes. It was considered by Bray et al. to belong in the superfamily Opecoeloidea Ozaki, 1925 or the Brachycladioidea Odhner, 1905.
Virgisporangium aurantiacum is a bacterium. It is a motile and spored species found in soil.
Virgibacillus is a genus of Gram-positive, rod-shaped (bacillus) bacteria and a member of the phylum Firmicutes. Virgibacillus species can be obligate aerobes, or facultative anaerobes and catalase enzyme positive. Under stressful environmental conditions, the bacteria can produce oval or ellipsoidal endospores in terminal, or sometimes subterminal, swollen sporangia. The genus was recently reclassified from the genus Bacillus in 1998 following an analysis of the species V. pantothenticus. Subsequently, a number of new species have been discovered or reclassified as Virgibacillus species.
Haliangium tepidum is a species of moderately halophilic myxobacteria. It produces yellow fruiting bodies, comprising several sessile sporangioles in dense packs. Its type strain is SMP-10.
Cryptosporangium aurantiacum is a bacterium.
Streptomyces graminisoli is a bacterium species from the genus of Streptomyces which has been isolated together with Streptomyces rhizophilus from rhizosphere soil from the plant Sasa borealis.
Virgisporangium is a genus of gram-positive bacteria. Virgisporangium are rod-shaped, motile, and form spores. They require oxygen to survive. They are generally found in the soil. The type species is Virgisporangium ochraceum, which was the first species of Virgisporangium described.
Streptomyces rhizophilus is a bacterium species from the genus of Streptomyces which has been isolated from rhizosphere soil from the plant Sasa borealis.
Azospirillum is a Gram-negative, microaerophilic, non-fermentative and nitrogen-fixing bacterial genus from the family of Rhodospirillaceae. Azospirillum bacteria can promote plant growth.
