Abstract
Laboratory-viable cultivars of previously uncultured bacteria further taxonomic understanding. Despite many years of modern microbiological investigations, the vast majority of bacterial taxonomy remains uncharacterized. While many attempts have been made to decrease this knowledge gap, culture-based approaches parse away at the unknown and are critical for improvement of both culturing techniques and computational prediction efficacy. To this end of providing culture-based approaches, we present a multi-faceted approach to recovering marine environmental bacteria. We employ combinations of nutritional availability, inoculation techniques, and incubation parameters in our recovery of marine sediment-associated bacteria from the Gulf of Mexico and Antarctica. The recovered biodiversity spans several taxa, with 16S-ITS-23S rRNA gene-based identification of multiple isolates belonging to rarer genera increasingly undergoing phylogenetic rearrangements. Our modifications to traditional culturing techniques have not only recovered rarer taxa, but also resulted in the recovery of biotechnologically promising bacteria. Together, we propose our stepwise combinations of recovery parameters as a viable approach to decreasing the bacterial knowledge gap.

Rhodococcus: sequences of genetic parts, analysis of their functionality, and development prospects as a molecular biology platform. Crit Rev Biotechnol 2023; 43:835-850. [PMID: 35786136 DOI: 10.1080/07388551.2022.2091976] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2021] [Revised: 04/19/2022] [Accepted: 05/12/2022] [Indexed: 12/19/2022]
Abstract
Rhodococcus bacteria are a fast-growing platform for biocatalysis, biodegradation, and biosynthesis, but not a platform for molecular biology. That is, Rhodococcus are not convenient for genetic engineering. One major issue for the engineering of Rhodococcus is the absence of a publicly available, curated, and commented collection of sequences of genetic parts that are functional in biotechnologically relevant species of Rhodococcus (R. erythropolis, R. rhodochrous, R. ruber, and R. jostii). Here, we present a collection of genetic parts for Rhodococcus (vector replicons, promoter regions, regulators, markers, and reporters) supported by a thorough analysis of their functionality. We also highlight and discuss the gaps in Rhodococcus-related genetic parts and techniques, which should be filled in order to make these bacteria a full-fledged molecular biology platform independent of Escherichia coli. We conclude that all major types of required genetic parts for Rhodococcus are available now, except multicopy replicons. As for model Rhodococcus strains, there is a particular shortage of strains with high electrocompetence levels and strains designed for solving specific genetic engineering tasks. We suggest that these obstacles are surmountable in the near future due to an intensification of research work in the field of genetic techniques for non-conventional bacteria.

[PMID: 37436164 PMCID: PMC10434288 DOI: 10.1128/spectrum.01360-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 06/24/2023] [Indexed: 07/13/2023] Open
Abstract
Bacteria are constantly exposed to a variety of environmental stresses. Temperature is considered one of the most important environmental factors affecting microbial growth and survival. As ubiquitous environmental microorganisms, Sphingomonas species play essential roles in the biodegradation of organic contaminants, plant protection, and environmental remediation. Understanding the mechanism by which they respond to heat shock will help further improve cell resistance by applying synthetic biological strategies. Here, we assessed the transcriptomic and proteomic responses of Sphingomonas melonis TY to heat shock and found that stressful conditions caused significant changes in functional genes related to protein synthesis at the transcriptional level. The most notable changes observed were increases in the transcription (1,857-fold) and protein expression (11-fold) of Hsp17, which belongs to the small heat shock protein family, and the function of Hsp17 in heat stress was further investigated in this study. We found that the deletion of hsp17 reduced the capacity of the cells to tolerate high temperatures, whereas the overexpression of hsp17 significantly enhanced the ability of the cells to withstand high temperatures. Moreover, the heterologous expression of hsp17 in Escherichia coli DH5α conferred to the bacterium the ability to resist heat stress. Interestingly, its cells were elongated and formed connected cells following the increase in temperature, while hsp17 overexpression restored their normal morphology under high temperature. In general, these results indicate that the novel small heat shock protein Hsp17 greatly contributes to maintaining cell viability and morphology under stress conditions. IMPORTANCE Temperature is generally considered the most important factor affecting metabolic functions and the survival of microbes. As molecular chaperones, small heat shock proteins can prevent damaged protein aggregation during abiotic stress, especially heat stress. Sphingomonas species are widely distributed in nature, and they can frequently be found in various extreme environments. However, the role of small heat shock proteins in Sphingomonas under high-temperature stress has not been elucidated. This study greatly enhances our understanding of a novel identified protein, Hsp17, in S. melonis TY in terms of its ability to resist heat stress and maintain cell morphology under high temperature, leading to a broader understanding of how microbes adapt to environmental extremes. Furthermore, our study will provide potential heat resistance elements for further enhancing cellular resistance as well as the synthetic biological applications of Sphingomonas.

Identification of Rhodococcus erythropolis Promoters Controlled by Alternative Sigma Factors Using In Vivo and In Vitro Systems and Heterologous RNA Polymerase. Curr Microbiol 2022; 79:55.

Abstract
Rhodococcus erythropolis CCM2595 is a bacterial strain, which has been studied for its capability to degrade phenol and other toxic aromatic compounds. Its cell wall contains mycolic acids, which are also an attribute of other bacteria of the Mycolata group, such as Corynebacterium and Mycobacterium species. We suppose that many genes upregulated by phenol stress in R. erythropolis are controlled by the alternative sigma factors of RNA polymerase, which are active in response to the cell envelope or oxidative stress. We developed in vitro and in vivo assays to examine the connection between the stress sigma factors and genes activated by various extreme conditions, e.g., heat, cell surface, and oxidative stress. These assays are based on the procedures of such tests carried out in the related species, Corynebacterium glutamicum. We showed that the R. erythropolis CCM2595 genes frmB1 and frmB2, which encode S-formylglutathione hydrolases (named corynomycolyl transferases in C. glutamicum), are controlled by SigD, just like the homologous genes cmt1 and cmt2 in C. glutamicum. The new protocol of the in vivo and in vitro assays will enable us to classify R. erythropolis promoters according to their connection to sigma factors and to assign the genes to the corresponding sigma regulons. The complex stress responses, such as that induced by phenol, could, thus, be analyzed with respect to the gene regulation by sigma factors.

Abstract
Rhodococci are bacteria which can survive under various extreme conditions, in the presence of toxic compounds, and in other hostile habitats. Their tolerance of unfavorable conditions is associated with the structure of their cell wall and their large array of enzymes, which degrade or detoxify harmful compounds. Their physiological and biotechnological properties, together with tools for their genetic manipulation, enable us to apply them in biotransformations, biodegradation and bioremediation. Many such biotechnological applications cause stresses that positively or negatively affect their efficiency. Whereas numerous reviews on rhodococci described their enzyme activities, the optimization of degradation or production processes, and corresponding technological solutions, only a few reviews discussed some specific effects of stresses on the physiology of rhodococci and biotechnological processes. This review aims to comprehensively describe individual stress responses in Rhodococcus strains, the interconnection of different types of stresses and their consequences for cell physiology. We examine here the responses to (1) environmental stresses (desiccation, heat, cold, osmotic and pH stress), (2) the presence of stress-inducing compounds (metals, organic compounds and antibiotics) in the environment (3) starvation and (4) stresses encountered during biotechnological applications. Adaptations of the cell envelope, the formation of multicellular structures and stresses induced by the interactions of hosts with pathogenic rhodococci are also included. The roles of sigma factors of RNA polymerase in the global regulation of stress responses in rhodococci are described as well. Although the review covers a large number of stressful conditions, our intention was to provide an overview of the selected stress responses and their possible connection to biotechnological processes, not an exhaustive survey of the scientific literature. The findings on stress responses summarized in this review and the demonstration of gaps in current knowledge may motivate researchers working to fill these gaps.

Abstract
BACKGROUND The rapid development of the rice wine industry has increased the demand for raw materials worldwide. A fungal strain with good adaptability to rice wine brewing conditions, which can also enhance the utilization rate of raw materials (URRM), thus increasing the production efficiency, was sought in the present research. RESULTS The strain FJMR24 was successfully isolated and screened from 35 fermentation starters and exhibited high amylase activity (2200.9 ± 18.5 U g-1 ) and high glucoamylase activity (2330.4 ± 31.9 U g-1 ). Based on a morphological examination and a sequence analysis of the internal transcribed spacer (ITS) gene and β-tubulin gene, FJMR24 was identified as Monascus purpureus, which is an edible and versatile fungus that plays a dominant role in the processing of Hong Qu. A moderate pH of 5-6 under incubation at 35 °C for 5-6 days was favorable for the growth and enzyme production of FJMR24. The strain could also tolerate the extreme conditions of 15-45 °C, 18% ethanol (v/v), and an acidity of pH 2. The excellent fermentation adaptability of FJMR24 might enable it to retain high enzyme activity during rice wine brewing. As a result of the action of FJMR24, the URRM of the base liquor increased by around 26% due to increased starch hydrolysis efficiency, which was mainly due to the high unit enzyme activity of FJMR24. CONCLUSION This study provides perspectives for the application of a M. purpureus strain with high starch hydrolysis activity for enhancing the URRM in traditional rice wine brewing. © 2020 Society of Chemical Industry.

Novel Chaperones RrGroEL and RrGroES for Activity and Stability Enhancement of Nitrilase in Escherichia coli and Rhodococcus ruber. Molecules 2020; 25:molecules25041002.

Abstract
For large-scale bioproduction, thermal stability is a crucial property for most industrial enzymes. A new method to improve both the thermal stability and activity of enzymes is of great significance. In this work, the novel chaperones RrGroEL and RrGroES from Rhodococcus ruber, a nontypical actinomycete with high organic solvent tolerance, were evaluated and applied for thermal stability and activity enhancement of a model enzyme, nitrilase. Two expression strategies, namely, fusion expression and co-expression, were compared in two different hosts, E. coli and R. ruber. In the E. coli host, fusion expression of nitrilase with either RrGroES or RrGroEL significantly enhanced nitrilase thermal stability (4.8-fold and 10.6-fold, respectively) but at the expense of enzyme activity (32-47% reduction). The co-expression strategy was applied in R. ruber via either a plasmid-only or genome-plus-plasmid method. Through integration of the nitrilase gene into the R. ruber genome at the site of nitrile hydratase (NHase) gene via CRISPR/Cas9 technology and overexpression of RrGroES or RrGroEL with a plasmid, the engineered strains R. ruber TH3 dNHase::RrNit (pNV18.1-Pami-RrNit-Pami-RrGroES) and TH3 dNHase::RrNit (pNV18.1-Pami-RrNit-Pami-RrGroEL) were constructed and showed remarkably enhanced nitrilase activity and thermal stability. In particular, the RrGroEL and nitrilase co-expressing mutant showed the best performance, with nitrilase activity and thermal stability 1.3- and 8.4-fold greater than that of the control TH3 (pNV18.1-Pami-RrNit), respectively. These findings are of great value for production of diverse chemicals using free bacterial cells as biocatalysts.

Abstract
Rhodococcus exhibits strong adaptability to environmental stressors and plays a crucial role in environmental bioremediation. However, seasonal changes in ambient temperature, especially rapid temperature drops exert an adverse effect on in situ bioremediation. In this paper, we studied the cell morphology and fatty acid composition of an aniline-degrading strain Rhodococcus sp. CNS16 at temperatures of 30 °C, 20 °C, and 10 °C. At suboptimal temperatures, cell morphology of CNS16 changed from short rod-shaped to long rod or irregular shaped, and the proportion of unsaturated fatty acids was upregulated. Transcriptomic technologies were then utilized to gain detailed insights into the adaptive mechanisms of CNS16 subjected to suboptimal temperatures. The results showed that the number of gene responses was significantly higher at 10 °C than that at 20 °C. The inhibition of peptidoglycan synthase expression and up-regulation of Filamentous Temperature Sensitive as well as unsaturated fatty acid synthesis genes at suboptimal temperatures might be closely related to corresponding changes in cell morphology and fatty acids composition. Strain CNS16 showed loss of catalase and superoxide dismutase activity, and utilized thioredoxin-dependent thiol peroxidase to resist oxidative stress. The up-regulation of carotenoid and Vitamin B2 synthesis at 10 °C might also be involved in the resistance to oxidative stress. Amino acid metabolism, coenzyme and vitamin metabolism, ABC transport, and energy metabolism are essential for peptidoglycan synthesis and regulation of cellular metabolism; therefore, synergistically resisting environmental stress. This study provides a mechanistic basis for the regulation of aniline degradation in Rhodococcus sp. CNS16 at low temperatures.
