TL;DR: The investigation of the response of a batch culture of Staphylococcus aureus to exogenous alkyl-substituted hydroxybenzenes (AHBs), chemical analogues of anabiosis autoinducers, showed that C1-AHB at concentrations from 5 μM to 1.5 mM did not influence the culture growth, whereas the more hydrophobic C6- AHB inhibited it.

TL;DR: Under experimentally selected conditions favoring spontaneous or induced autolysis of cell suspensions, the asporogenous bacteria Escherichia coli and Methylococcus capsulatus, the bacilli Bacillus cereus, and the yeast Saccharomyces cerevisiae were shown to be capable of forming cystlike resting cells.

TL;DR: X-ray microanalysis of the elemental composition of bacteriomorphic particles in 170 000-year-old Antarctic permafrost sediments and in indoor dust showed that the absence of P and/or S peaks in the X-ray spectrum of an object may indicate that it is abiotic.

TL;DR: The results suggest a new approach to optimizing sporulation by acidophilic chemolithotrophs, which consists in limiting the energy and nutrient sources and using temperature and pH values within the tolerance bounds of these cultures but outside their growth optimum ranges.

TL;DR: Under certain cultivation conditions, the bacteria Bacillus cereus and Micrococcus luteus form cystlike refractive cells that retain viability over a long time, are metabolically inactive and thermotolerant and possess specific ultrastructure that allow them to be attributed to a new type of resting forms of microorganisms.
