Solibacillus kalamii is a Gram-positive, rod-shaped, endospore-forming and aerobic bacterium from the genus of Solibacillus which has been isolated from a high-efficiency particulate arrestance filter system from the International Space Station. [1] [2] [3] [4] [5]
The bacteria is named after the late President of India, Dr. A.P.J. Abdul Kalam, who was a renowned Indian aerospace scientist.
The bacteria was found in the high-efficiency particulate arrestance filter or HEPA filter, which is the routine housekeeping and cleaning system on board the International Space Station. The filter on which the new bug was found remained on board the ISS for 40 months. This filter was later analysed at the Jet Propulsion Laboratory (JPL), the foremost lab of NASA for work on interplanetary travel, in 2017. The discovery was published by Dr. Kasthuri Venkateswaran, senior research scientist, Biotechnology and Planetary Protection Group, in the International Journal of Systematic and Evolutionary Microbiology.
They tend to withstand high radiation and also produce some useful compounds protein-wise which will be helpful for biotechnology applications. Researchers have not characterised the bacteria fully but they are of the view that the new bug could be a key source for chemicals that can help protect against radiation damage.
The Thermomicrobia is a group of thermophilic green non-sulfur bacteria. Based on species Thermomicrobium roseum and Sphaerobacter thermophilus, this bacteria class has the following description:
Bacillus odysseyi is a Gram-positive, aerobic, rod-shaped, round-spore- and endospore-forming eubacterium of the genus Bacillus. This novel species was discovered by scientist Myron T. La Duc of NASA’s Biotechnology and Planetary Protection Group, a unit whose purpose is to clean and sterilize spacecraft so as not to have microorganisms contaminate other celestial bodies or foreign microorganisms contaminate Earth, on the surface of the Mars Odyssey in a clean room at the Jet Propulsion Laboratory in La Cañada Flintridge before the spacecraft was launched to space. La Duc named the bacterium Bacillus odysseyi sp. nov. after the Odyssey mission. It had apparently evolved to live in the sparse environment of a clean room, and its secondary spore coat makes it especially resistant to radiation.
Solibacillus is a genus of Gram positive, rod shaped, spore-forming bacteria.
Patulibacter is a genus of bacteria from the family Patulibacteraceae.
Sphaerisporangium is a Gram-positive genus of bacteria from the family of Streptosporangiaceae.
Solirubrobacter is a Gram-positive, spore-forming, aerobic, mesophilic and non-motile genus of bacteria from the family Solirubrobacteraceae.
Caldanaerovirga is a xylanolytic, anaerobic and alkalithermophilic genus of bacteria from the family of Thermosediminibacterales with one known species.
Anaerolineaceae is a family of bacteria from the order of Anaerolineales. Anaerolineaceae bacteria occur in marine sediments. There are a total of twelve genera in this family, most of which only encompass one species. All known members of the family are Gram-negative and non-motile. They also do not form bacterial spores and are either mesophilic or thermophilic obligate anaerobes. It is also known that all species in this family are chemoheterotrophs.
Solibacillus isronensis is a bacterium from the genus of Solibacillus which has been isolated from a cryogenic tube from India. It is named after ISRO, India's space agency which discovered the species.
Knoellia is a genus of Gram positive, aerobic, non-endosporeforming bacteria. Species in this genus are mesophilic and have cells that are irregular rods or coccoid.
Knoellia remsis a species of Gram positive, nonmotile, non-sporeforming bacteria. The bacteria are aerobic and mesophilic, and the cells are coccoid that group in pairs, tetrads, or clusters. It was originally isolated from an air sample from the Regenerative Enclosed Life Support Module Simulator, which was a system designed to simulate life aboard the International Space Station. The species is named after REMS, the acronym for the Regenerative Enclosed Life Support Module Simulator. The species was originally classified as Tetrasphaera remsis in 2007, but was reclassified into the genus Knoellia in 2018.
Metabacillus is a genus of rod-shaped bacteria exhibiting Gram-positive or Gram-variable staining in the family Bacillaceae within the order Bacillales. The type species for this genus is Metabacillus fastidiosus.
