In conserving with the researchers, bacterial cellulose enables microbial life on Mars.
A bunch of researchers from Göttingen College investigates kombucha cultivation in extraterrestrial environments.The prospective for kombucha cultures surviving below Martian-admire environments has been studied by a worldwide review group that involves the College of Göttingen. Kombucha, additionally identified as tea fungus or mushroom tea, is a favored beverage that is made by fermenting sugared tea utilizing kombucha cultures, a symbiotic culture of micro organism and yeast.
Surprisingly, a bacterial species that produces cellulose persisted no topic the simulated Martian atmosphere destroying the kombucha cultures’ microbial ecology. The findings had been revealed within the journal Frontiers in Microbiology.
In 2014, with the serve of the European Space Agency, the researchers working on the “Biology and Mars Experiment” (BIOMEX) project launched kombucha cultures to the International Space Attach (ISS).

The unbiased became to uncover a much bigger belief of cellulose’s resilience as a biomarker, kombucha’s genomic structure, and its extraterrestrial survival behavior. The samples had been reactivated on Earth and cultured for one other two and a half years after one and a half years below simulated Martian instances outside the ISS.
Working alongside researchers from the College of Minas Gerais in Brazil, Professor Bertram Brenig, director of the College of Göttingen’s Institute of Veterinary Medication, became guilty of sequencing and bioinformatic analysis of the metagenomes of the reactivated cultures and particular person kombucha cultures.
“In line with our metagenomic analysis, we found that the simulated Martian ambiance critically disrupted the microbial ecology of kombucha cultures. Nevertheless, we had been taken aback to search out that the cellulose-producing micro organism of the genus Komagataeibacter survived.”

The outcomes imply that the cellulose produced by the micro organism is doubtlessly guilty for his or her survival in extraterrestrial instances. This additionally affords the first proof that bacterial cellulose on the total is a biomarker for extraterrestrial life and cellulose-primarily based mostly membranes or movies on the total is an efficient biomaterial for holding life and producing user goods in extraterrestrial settlements.
One more attention-grabbing aspect of these experiments would possibly perhaps be the strategy of new drug supply programs, as an instance, the strategy of medication actual to be used in apartment. One more focal level became on investigations into adjustments in antibiotic resistance: the review group became in a put to level that the total series of antibiotic and metal resistance genes – which intention that these microorganisms would possibly perhaps maybe perhaps well also survive no topic antibiotics or metals within the ambiance – had been enriched within the exposed cultures.
“This result presentations that the difficulties linked to antibiotic resistance in medication in apartment ought to silent be given special consideration within the lengthy scoot,” the scientists stated.
