Quantification of polyprenyl diphosphates in Escherichia coli cells using high-performance liquid chromatography
Biosci Biotechnol Biochem. 2024 Jan 8:zbae001. doi: 10.1093/bbb/zbae001. Online ahead of print.ABSTRACTDephosphorylation of undecaprenyl diphosphate is a crucial step in the synthesis of undecaprenyl phosphate, which is essential for cell wall synthesis. We have developed a method for the quantification of intracellular polyprenyl diphosphates, which have never before been measured directly. Polyprenyl phosphates and diphosphates prepared by chemical phosphorylation of polyprenols from Staphylococcus aureus were used to establish the conditions for fractionation by ion-exchange chromatography and high-performance liquid ch...

Three distinct metabolic phases of PCB/biphenyl degrader Acidovorax sp. KKS102 in nutrient broth
In this study we examined its growth in liquid nutrient broth supplemented with different carbon sources. KKS102 had at least three distinct metabolic phases designated as metabolic phases 1 to 3, with phase 2 having two sub-phases. For example, succinate, fumarate, and glutamate, known to repress the PCB/biphenyl catabolic operon in KKS102, were utilized in phase 1, while acetate, arabinose, and glycerol in phase 2, and glucose and mannose in phase 3. We also showed that the BphQ response regulator mediating catabolite control in KKS102, whose expression level increased moderately through the growth, plays important roles...

The community of lactic acid bacteria during kimoto-style seed mash making process and its control
Biosci Biotechnol Biochem. 2024 Jan 5:zbad182. doi: 10.1093/bbb/zbad182. Online ahead of print.ABSTRACTKimoto-style seed mash making processes such as the kimoto and yamahai-moto processes are driven by various microorganisms, and it is very important to make lactic acid bacteria grow stably for the brewing of a sake product with consistent quality. A model of bacterial transition from spherical lactic acid bacteria to rod-shaped lactic acid bacteria during kimoto-making has been advocated, but the model cannot explain all cases of a transition of a bacterial community during kimoto-making at various breweries. Several stu...

Specialized metabolites degradation by microorganisms
Biosci Biotechnol Biochem. 2024 Jan 2:zbad184. doi: 10.1093/bbb/zbad184. Online ahead of print.ABSTRACTSecondary metabolites are specialized metabolic products synthesized by plants, insects, and bacteria, some of which exhibit significant physiological activities against other organisms. Plants containing bioactive secondary metabolites have been used in traditional medicine for centuries. In developed countries, one-fourth of medicines directly contain plant-derived compounds or indirectly contain them via semi-synthesis. These compounds have contributed considerably to the development of not only medicine but also molec...

High fatty acid accumulation and coloration molecular mechanism of the elm mushroom (Pleurotus citrinopileatus)
In conclusion, the expression of three SREBP, the synthesis of isobavachalcone D, and the regulation of riboflavin transport by MCH5 were the reasons for fatty acid accumulation and yellow cap formation in the P. citrinopileatus.PMID:38171531 | DOI:10.1093/bbb/zbad183 (Source: Bioscience, Biotechnology, and Biochemistry)

Pathogenicity of enterotoxigenic Escherichia coli in Caenorhabditis elegans as an alternative model host
In this study, Caenorhabditis elegans was used as an alternative model host to evaluate ETEC infections. The ETEC strain ETEC1, which was isolated from a patient with diarrhea, possessed enterotoxins STh, LT1, and EAST1 and colonization factors CS2 and CS3. Live ETEC1 shortened the lifespan and body size of C. elegans in association with increased expression of enterotoxin genes and intestinal colonization. In contrast, heat-killed ETEC1 did not affect the lifespan of C. elegans. C. elegans infected with ETEC1 showed upregulated expression of genes related to insulin-like peptides and host defense responses. These results ...
