New bacterial genera named Sapientia

Microbiologists from Sapientia University and Eötvös Loránd University, Budapest, have isolated in the water of crater lake Sfânta Ana a new and unknown bacterial genera, naming it Sapientia aquatica.

At the Department of Bioengineering of Sapientia University in Miercurea-Ciuc students from the Environmental Engineering and Environmental Protection in Industry study programme involved in the microbiological research of the volcanic lake lead by dr. István Máthé, associate professor, have grown and identified based on DNA analysis several bacterial generas and species, which were unknown up to now. The research team has recently described a new bacterial genera (Siculibacillus lacustris), as well as a new species (Rhizobium aquaticum).

The comprehensive molecular biology and biochemical analysis, which were necessary for describing the newest bacterial genera identified in the crater lake, were lead by dr. Tamás Felföldi, microbiologist at Eötvös Loránd University, and the results have recently been published in one of the most renowned scientific paper.

In the genera name of the bacteria the word “Sapientia” indicates that it has been isolated in the laboratories of Sapientia University, while “aquatica” refers to its origin. The newly discovered species breaks down several types of sugar and fat molecules, thereby playing an important part in the cycle of nutrients found in the lake.

Nine bacteria generas have been named earlier after universities from the entire globe (South Coreea, Japan, China, Australia and Hungary), such as Eoetvoesia, which was named in honor of Hungarian physicist Loránd Eötvös (1848-1919) by the microbiologists of the university that also bears his name. Two microorganisms go by the names of the scientists that Babeș-Bolyai University was named after: the Babesia genera from the group of protozoa (unicellular organisms of animal origin) bears the name of Romanian physician and bacteriologist Victor Babeș (1854-1926), while the Chlamydomonas bolyaiana green algae species was “baptized” in honor of the two mathematicians, Farkas Bolyai (1775-1856) and his son, János Bolyai (1802-1860).

As for bacteriology terms, the Friedmanniella genera bears the name of Hungarian microbiologist Imre Friedmann (1921-2007), who focused on researching the deserts in warm climates and Antarctica, while the Gimesia genera was named after botanist, hydrobiologist and microbiologist Nándor István Gimesi (1892-1953). The name of Nitrincola schmidtii bacteria is an homage to algae researcher Antal Schmidt (1944-2010), and the Xenorhabdus szentirmaii was named after Attila Szentirmai (1930-2019), who dedicated his life to industrial microbiology, and who died in the recent past.

As for Romanian researchers, the Parabacteroides distasonis species bears the name of Arcangelo Distaso, who carried out his activity in the 1910s at the Pasteur Institute in Paris.
