Discoveries in Microbiology (GATE)

The bacterium Propionibacterium acne type zappa colonises bark tissues and the pith of grapevine where the bacterium can localise intracellularly. This bacterium is the first evidence of human to plant obligate transfer.

Tersicoccus phoenicis was identified in the clean room facilities of the spacecraft. They are able to survive the hard sterilisation procedures used to sterilise the clean rooms of the spacecraft.

Lactocillin is produced by an organism of the vaginal biome. It was isolated from Lactobacillus bacterium, which resides in the vagina.

Streptomyces chilikensis and Streptomyces barkulensis cannot tolerate extreme temperature.

Eleftheria terrae produces teixobactin. It was previously an unculturable bacterium, which was cultured in the soil. It is active against Staphylococcus aureus or Mycobacterium tuberculosis.

Correct Answer: It can oxidise ammonia.

The bacteria responsible for the outbreak at Lutheran hospital were Carbapenem-resistant enterobacteriaceae. Carbapenems are often referred to as last-resort antibiotics. These bacteria possessed enzymes which can deactivate Carbapenem, making them resistant to this antibiotic.

Borrelia mayoni was discovered in 2016. It causes Lyme disease. Illness caused by B. mayonii is similar to that caused by B. burgdorferi, but with a few possible differences. B. mayonii is associated with nausea and vomiting, diffuse rashes and a higher concentration of bacteria in the blood.

Geobacter and Shewanella eat pure electrons.

Ideonella sakaiensis has potential of recycling of PET plastics. The bacterium was observed to utilise two distinct enzymes that reacted with water to break down PET (polyethylene terephthalate) plastics.

Dr. Bas E. Dutilh at Radboud University Medical Centre in Netherlands discovered crassphage. It keeps us healthy by preying on bacteroides. This virus infects bacteroides, which can be pathogens for humans.

The bacterial strain Komagataeibacter sucrofermentans DSM 15973 was used for the production of bacterial cellulose from industrial wastes in 2015.

The scientist at Genome Institute of Singapore, in 2014, discovered three powerful bacteria from a genus called Dehalococcoides. They can degrade PCBs.

Legionella pneumophila was found in the cooling tower of the US plant. This bacterium causes a lethal form of pneumonia.

Bdellovibrio is entirely dependent on the other bacteria it infects. It was discovered in 2016 from saliva. It is an ultra-small bacteria and lives on the surface of other bacteria, which makes its host more harmful to humans.
