In order to achieve the titer, yield and productivity values required for economically viable processes, the carboxylic acid-producing microbes need to be robust and well-performing.
These results suggest that TauBr may contribute to host defense against microbes, although this still needs to be confirmed in vivo.
Although extensive experimental data suggested gut microbiota manipulation can beneficially affect host adiposity and glucose metabolism, a causal relationship between gut microbes and obesity still needs to be proven in humans, in whom current data suggest an association between gut microbiota, Western diet, and obesity.
In order to acquire more alginate lyase-excreting microbes, a simple and efficient screening method needs to be developed.
The work needs to be replicated, but the microbes "have a good chance of being that old," Cano says.
Water needs to be clean, free of toxins and microbes to prevent disease.
To survive, however, the microbes would need to be shielded from the harsh ultraviolet radiation that continually blasts the surface of Mars, as well as have access to a source of water, organic carbon and nitrogen.
For use in gastroenterology, it is important that a preparation contains sufficient quantities of microbes which need to be acid and enzyme resistant with good mucosal adherence also being an advantage.
Mark Achtman, an expert on plague who works at University College Cork in Ireland, said that the new study was "technologically interesting" but that a great deal more of the microbe's DNA needed to be sequenced to obtain scientifically important results.
And to account for the differences between microbes and cancers, future experimental studies need to be conducted to explicitly test evolutionary theory within the context of cancer.
