“…One of the adaptation mechanisms for nutritional deficiency under suboptimal conditions of existence in bacteria is the synthesis of reserve substances [ 27 , 32 , 36 ]. In the cultures of Y. pseudotuberculosis that we studied, the ability to synthesize polyphosphates and poly- β -hydroxybutyric acid (PHBA) was found [ 30 ].…”

“…It was established [25] that conformational changes in the structure of the active surface of enzymes, leading to an increase in catalytic activity which accelerates biochemical reactions in bacterial cells, underlie bacterial adaptation. Under the favorable trophic conditions, the ability of Y. pseudotuberculosis to accumulate reserve substances (β-hydroxybutyric acid, polyphosphates) and to consume them under fasting conditions has been proven [26,27].…”

“…It was concluded that these changes in bacteria of periodic and soil cultures that ensure their functional usefulness should be considered as an adaptive response of bacterial populations to changing living conditions, which demonstrates the universal, morphological mechanism of their adaptation [30,31]. A long stay of Y. pseudotuberculosis in the soil is provided by phenotypic changes at the ultrastructure level and is expressed in the formation of a capsule and microcapsule, general cover, mucus, intercellular contacts, cytoplasmic outgrowths (prostakes), and accumulation of reserve substances [25,27,32]. Functional adaptation is also provided by an increase in tortuosity and a change in the thickness of the cell wall, variability in the size of bacteria, ribosomal saturation of the cytoplasm and the state of the nucleoid, which reflects conformational changes in bacterial DNA.…”

Pseudotuberculosis in humans until the 1950s was found in different countries of the world as a rare sporadic disease that occurred in the form of acute appendicitis and mesenteric lymphadenitis. In Russia and Japan, the Yersinia pseudotuberculosis (Y. pseudotuberculosis) infection often causes outbreaks of the disease with serious systemic inflammatory symptoms, and this variant of the disease has been known since 1959 as Far Eastern Scarlet-like Fever (FESLF). Russian researchers have proven that the FESLF pathogen is associated with a concrete clonal line of Y. pseudotuberculosis, characterized by a specific plasmid profile (pVM82, pYV 48 MDa), sequence (2ST) and yadA gene allele (1st allele). This review summarized the most important achievements in the study of FESLF since its discovery in the Far East. It has been established that the FESLF causative agent is characterized by a unique phenomenon of psychrophilicity, which consists of its ability to reproduce in the environment with its biologically low and variable temperature (4–12 °C), at which the pathogen multiplies and accumulates while maintaining or increasing its virulence, which ensures the emergence and development of the epidemic process. The key genetic and biochemical mechanisms of Y. pseudotuberculosis adaptation to changing environmental conditions were characterized, and the morphological manifestations of the adaptive variability of these bacteria in different conditions of their habitat were revealed. The main features of the pathogenesis and morphogenesis of FESLF, including those associated with the Y. pseudotuberculosis toxigenicity, were presented. The pathogenetic value of the plasmid PVM82, found only in the FESLF pathogen, was shown.

“…Finally, PolyP is believed to be central to the survival strategies of certain modern bacteria. At low temperatures, when phosphate is available but nitrogen is scarce, Yersinia pseudotuberculosis and Listeria monocytogenes store the phosphate as PolyP for future use [ 35 ]. In the cyanobacterium, Aphanizomenon ovalisporum , the huge increase in DNA as dormant cells are formed probably depends on phosphate provided by PolyP bodies; this increase is believed to allow long-term survival during stress and a subsequent rapid resumption of metabolism and cell division when conditions improve [ 36 ].…”

Molecular complementarity between simple, universal molecules and ions limited phenotype space in the precursors of cells

BackgroundFundamental problems faced by the protocells and their modern descendants include how to go from one phenotypic state to another; escape from a basin of attraction in the space of phenotypes; reconcile conflicting growth and survival strategies (and thereby live on ‘the scales of equilibria’); and create a coherent, reproducible phenotype from a multitude of constituents.Presentation of the hypothesisThe solutions to these problems are likely to be found with the organic and inorganic molecules and inorganic ions that constituted protocells, which we term SUMIs for Simple Universal Molecules and Ions. These SUMIs probably included polyphosphate (PolyP) as a source of energy and of phosphate; poly-(R)-3-hydroxybutyrate (PHB) as a source of carbon and as a transporter in association with PolyP; polyamines as a source of nitrogen; lipids as precursors of membranes; as well as peptides, nucleic acids, and calcium. Here, we explore the hypothesis that the direct interactions between PHB, PolyP, polyamines and lipids – modulated by calcium – played a central role in solving the fundamental problems faced by early and modern cells.Testing the hypothesisWe review evidence that SUMIs (1) were abundant and available to protocells; (2) are widespread in modern cells; (3) interact with one another and other cellular constituents to create structures with new functions surprisingly similar to those of proteins and RNA; (4) are essential to creating coherent phenotypes in modern bacteria. SUMIs are therefore natural candidates for reducing the immensity of phenotype space and making the transition from a “primordial soup” to living cells.Implications of the hypothesisWe discuss the relevance of the SUMIs and their interactions to the ideas of molecular complementarity, composomes (molecular aggregates with hereditary properties based on molecular complementarity), and a prebiotic ecology of co-evolving populations of composomes. In particular, we propose that SUMIs might limit the initial phenotype space of composomes in a coherent way. As examples, we propose that acidocalcisomes arose from interactions and self-selection among SUMIs and that the phosphorylation of proteins in modern cells had its origin in the covalent modification of proteins by PHB.ReviewersThis article was reviewed by Doron Lancet and Kepa Ruiz-Mirazo.

Polyphosphate accumulating organisms were isolated from water and sludge samples of intensive catfish ponds in the Mekong Delta, Vietnam. The Results of estimation of intracellular polyphosphate concentration conducted on each of monocultures indicated that the content of intracellular polyphosphate varied from 2 mg/l to 148.1 mg/l after 6 days of incubation in the medium. Of 191 isolates, twenty-one have uptake and store intracellular phosphate from 19.6 to 148.1 mg/l. They have shaped like a rods and short rods or cocci, a few of them were slightly curved or straight or curved rods. The majority of them are gram-positive (76.2%) and the remains are gram-negative. The partial 16S rRNA genes of these isolates were sequenced and compared with bacterial 16S rRNA genes in Genbank using BlastN Program. Phylogenetic tree was constructed on the basic 16S rRNA gene sequences demonstrating the population of high phosphate accumulating bacteria obtained from samples of catfish ponds were affiliated with four major bacterial lineages. Twenty-one bacteria isolates from samples of catfish ponds included in four classes: Bacilli, Actinobacteria, Beta-proteobacteria, Gamma-proteobacteria. The majority of the strains showed excess phosphate accumulation. Strains related to Bacillus sp. were dominant bacteria group constituted up to 52.4% of all identified isolates, but high phosphate accumulating bacteria are Burkholderia vietnamiensis TVT003L within class Beta-proteobacteria, Acinetobacter radioresistens TGT013L within Gamma-proteobacteria and Arthrobacter protophomiae VLT002L within class Actinobacteria. Methyl blue Loeffler's staning and electron microscopy examination confirmed that the bacteria had stored polyphosphate granules intracellularly.
