We hypothesize that a shrinking bile acid pool leads to increases in microbes with potent pro-inflammatory molecules coupled with production of harmful metabolites, which in turn lead to further down-regulation of bile acid synthesis in a positive-feedback mechanism via inflammation.
Medicines use is increasing globally with the increase in resistant microbes, emergence of new treatments, and because of awareness among consumers.
IBD patients with active disease show altered microbial diversity [ 27] with an increase in pathogenic microbes such as Escherichia coli as compared to healthy control subjects [ 28].
These changes also pertained to butyrate-producing bacterial strains (Butyrivibrio fibrisolvens P(corr) = 0.80, Clostridium saccharolyticum (P(corr) = 0.94), Eubacterium limosum (P(corr) = 0.90), and Blautia hydrogenotrophica (P(corr) = 0.88)), but here resulting in an increase in those microbes.
In the area around the breach, Caltech scientists found a massive increase in previously unknown microbes that inhabit the soil and appear to consume ethane and possibly methane.
Therefore, the observed ten-fold increase in abundance of microbes, in both the direct counts and by culturing, has the very real potential of killing corals in Kiritimati.
More detailed BLASTX search of Illumina reads against the ACLAME DB indicated that the relative abundance of total phage DNA reads in the polluted soil increased at Weeks 3 and 6 (Fig. 5A), supporting the notion of an increase in prophage-carrying microbes and/or phage particles in the soil.
Increasing atoll size and oceanographically more oligotrophic water were directly correlated with significant increases in protists, microbes, and VLPs.
Specifically, we make three predictions that can be experimentally examined: (1) All else being equal, higher rates of PCD should increase phenotypic heterogeneity in microbes that stochastically diversify as a consequence of reproduction.
Understanding these pathways allows scientists to boost or inhibit specific reactions, which can in turn increase the microbe's efficiency at creating a particular fuel or end product.
