sp. nov. and sp. nov., isolated from the Mekong River in Thailand.

Four newly discovered Gram-stain-negative bacteria, designated as BL00010, BL00058, D8-11 and BL00200, were isolated from water samples collected at three hydrological monitoring stations (namely Chiang Saen, Chiang Khan and Nong Khai) located along the Mekong River in Thailand. An investigation encompassing phenotypic, chemotaxonomic and genomic traits was conducted. The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that all four isolates represented members of the genus .

Interplay of xenobiotic-degrading and antibiotic-resistant microorganisms among the microbiome found in the air, handrail, and floor of the subway station.

Investigating the quality of the subway environment, especially regarding antibiotic resistance genes (ARGs) and xenobiotics, conveys ecological and health impacts. In this study, compositions and relations of microorganisms harboring ARGs and xenobiotic degradation and metabolism genes (XDGs) in the Sukhumvit subway station (MRT-SKV) in Bangkok was assessed by analyzing the taxonomic and genetic diversity of the microbiome in the air and on the surfaces of floor and handrail. The major bacteria in the MRT-SKV (including Moraxella, which was abundant in the bioaerosol and handrail samples, and Staphylococcus, which was abundant in the bioaerosol samples) were found to contain both ARGs and XDGs.

AirDNA sampler: An efficient and simple device enabling high-yield, high-quality airborne environment DNA for metagenomic applications.

Analyzing temporal and spatial distributions of airborne particles of biological origins is vital for the assessment and monitoring of air quality, especially with regard to public health, environmental ecology, and atmospheric chemistry. However, the analysis is frequently impeded by the low levels of biomass in the air, especially with metagenomic DNA analysis to explore diversity and composition of living organisms and their components in the air. To obtain sufficient amounts of metagenomic DNA from bioaerosols, researchers usually need a long sampling time with an expensive high-volume air sampler.

Incidence, genetic diversity, and antimicrobial resistance profiles of in seafood in Bangkok and eastern Thailand.

Background: Emergence of pandemic strain O3:K6 was first documented in 1996. Since then it has been accounted for large outbreaks of diarrhea globally. In Thailand, prior studies on pandemic and non-pandemic had mostly been done in the south.

Temporal, compositional, and functional differences in the microbiome of Bangkok subway air environment.

With the growing numbers of the urban population, an increasing number of commuters have relied on subway systems for rapid transportation in daily life. Analyzing the temporal distribution of air microbiomes in subway environments is crucial for the assessment and monitoring of air quality in the subway system, especially with regard to public health. This study employed culture-independent metabarcode sequencing to analyze bacterial diversity and variations in bacterial compositions associated with bioaerosols collected from a subway station in Bangkok over a four-month period.

sp. nov., an osmotolerant acetic acid bacterium isolated in Thailand and emended description of the genus .

A novel Gram-stain-negative, rod-shaped, non-motile, aerobic bacterium isolated from a sea bean flower [ (Sw.) DC.] collected in Surat Thani Province, Thailand, and designated as AH18 was characterized on the basis of polyphasic taxonomy.

High level of calcium carbonate precipitation achieved by mixed culture containing ureolytic and nonureolytic bacterial strains.

This study demonstrates a remarkably high level of microbial-induced calcium carbonate precipitation (MICP) using a mixed culture containing TBRC 1396 (Priestia megaterium), TBRC 8147 (Neobacillus drentensis) and ATCC 11859 (Sporosarcina pasteurii) bacterial strains. The mixed culture produced CaCO weights 1·4 times higher than those obtained from S. pasteurii, the gold standard for efficient MICP processes.

The Fungus sp. BCC 4849 Is an Effective and Safe Mycoinsecticide for the Management of Spider Mites and Other Insect Pests.

Five isolates of sp. were evaluated for their pathogenicity against the spider mite ( Ehara) (Acari: Tetranychidae) and sp. BCC 4849 resulted in the highest mortality (82%) on the 5th day post-inoculation (DPI).

sp. nov., an acetic acid bacterium isolated from fermented mangosteen peel in Thailand.

Two isolates, MS16-SU-2 and MS18-SU-3, obtained from fermented mangosteen peel in vinegar were suggested to constitute a new species assignable to the genus based on the results of 16S rRNA gene sequencing. The two isolates showed the highest sequence similarity (98.58%) to NBRC 16470 and LMG 23690.

Iron homeostasis in the absence of ferricrocin and its consequences in fungal development and insect virulence in Beauveria bassiana.

The putative ferricrocin synthetase gene ferS in the fungal entomopathogen Beauveria bassiana BCC 2660 was identified and characterized. The 14,445-bp ferS encodes a multimodular nonribosomal siderophore synthetase tightly clustered with Fusarium graminearum ferricrocin synthetase. Functional analysis of this gene was performed by disruption with the bar cassette.

The repertoire of ABC proteins in .

ATP-binding cassette (ABC) transporters belong to one of the largest membrane protein superfamilies, which function in translocating substrates across biological membranes using energy from ATP hydrolysis. Currently, the classification of ABC transporters in is not complete. Therefore, the sequence-function relationship of all ABC proteins encoded within the genome was analyzed.

Identification of proteins responsive to heterologous protein production in thermotolerant methylotrophic yeast Ogataea thermomethanolica TBRC656.

The thermotolerant methylotrophic yeast Ogataea thermomethanolica TBRC656 is a potential host for heterologous protein production. However, overproduction of heterologous protein can induce cellular stress and limit the level of its secretion. To improve the secretion of heterologous protein, we identified the candidate proteins with altered production during production of heterologous protein in O.

Uncovering multi-faceted taxonomic and functional diversity of soil bacteriomes in tropical Southeast Asian countries.

Environmental microbiomes encompass massive biodiversity and genetic information with a wide-ranging potential for industrial and agricultural applications. Knowledge of the relationship between microbiomes and environmental factors is crucial for translating that information into practical uses. In this study, the integrated data of Southeast Asian soil bacteriomes were used as models to assess the variation in taxonomic and functional diversity of bacterial communities.

Dysregulation of microRNA in cholangiocarcinoma identified through a meta-analysis of microRNA profiling.

Background: In the past decades, the potential of microRNA (miRNA) in cancer diagnostics and prognostics has gained a lot of interests. In this study, a meta-analysis was conducted upon the pooled miRNA microarray data of cholangiocarcinoma (CCA).

Aim: To identify differentially expressed (DE) miRNAs and perform functional analyses in order to gain insights to understanding miRNA-target interactions involved in tumorigenesis pathways of CCA.

Mating-type switching and mating-type gene array expression in the methylotrophic yeast Ogataea thermomethanolica TBRC656.

The methylotrophic yeast, Ogataea thermomethanolica TBRC656, is an attractive host organism for heterologous protein production owing to the availability of protein expression vectors and a genome-editing tool. In this study, we focused on mating-type switching and gene expression in order to elucidate its sexual life cycle and establish genetic approaches applicable for the strain. A putative mating-type gene cluster was identified in TBRC656 that is syntenic to the cluster in Ogataea parapolymorpha DL-1 (previously named Hansenula polymorpha).

Meta-analysis of gene expression profiles identifies differential biomarkers for hepatocellular carcinoma and cholangiocarcinoma.

Hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) are the members of hepatobiliary diseases. Both types of cancer often exert high levels of similarity in terms of phenotypic characteristics, thus leading to difficulties in HCC and CCA differential diagnoses. In this study, a transcriptome meta-analysis was performed on HCC and CCA microarray data to identify differential transcriptome networks and potential biomarkers for HCC and CCA.
