Biocontrol potential of ML15 against causing gray mold on postharvest tomato ( var. ).

Gray mold, caused by is a major cause of post-harvest rot of fresh fruits and vegetables. The utilization of selected microorganisms as biocontrol agents is a promising alternative to effectively control gray mold on tomatoes. The current study was conducted to explore potential biocontrol mechanisms of the strain to control infections on post-harvest tomatoes.

Spoligotyping of Mycobacterium tuberculosis - Comparing in vitro and in silico approaches.

Spoligotyping is one of the molecular typing methods widely used for exploring the genetic variety of Mycobacterium tuberculosis. The aim of this study was to compare the spoligoprofiles of M. tuberculosis clinical isolates, obtained using in vitro and in silico approaches.

Revealing the diversity of bacteria and fungi in the active layer of permafrost at Spitsbergen island (Arctic) - Combining classical microbiology and metabarcoding for ecological and bioprospecting exploration.

Arctic soils are constantly subjected to extreme environmental conditions such as low humidity, strong winds, high salinity, freeze-thaw cycles, UV exposition, and low nutrient availability, therefore, they have developed unique microbial ecosystems. These environments provide excellent opportunities to study microbial ecology and evolution within pristine (i.e.

Fresh Versus Frozen Stool for Fecal Microbiota Transplantation-Assessment by Multimethod Approach Combining Culturing, Flow Cytometry, and Next-Generation Sequencing.

The objective of this work was to compare the quality of FMT preparations made from fresh feces with those made from feces frozen at -30°C without any pre-processing or cryopreservation additives. The research hypothesis was that such preservation protocol (frozen whole stool, then thawed and processed) is equipotent to classical fresh FMT preparation. For that, three complementary methods were applied, including: (i) culturing in aerobic and anaerobic conditions, (ii) measuring viability by flow cytometry, and (iii) next-generation sequencing.

Draft Genome Sequence of Arctic, Heavy Metal-Resistant sp. Strain ARC_14 Isolated from Active Layer of Permafrost from Spitsbergen (Norway).

Extreme environmental conditions observed in polar regions create a unique ecological niche for microbial life. Bacteria living under these harsh, environmental conditions exhibit specific metabolic capabilities. In this report, we present multimetal-resistant sp.

Modelling hCDKL5 Heterologous Expression in Bacteria.

hCDKL5 refers to the human cyclin-dependent kinase like 5 that is primarily expressed in the brain. Mutations in its coding sequence are often causative of hCDKL5 deficiency disorder, a devastating neurodevelopmental disorder currently lacking a cure. The large-scale recombinant production of hCDKL5 is desirable to boost the translation of preclinical therapeutic approaches into the clinic.

Metaplasmidome-encoded functions of Siberian low-centered polygonal tundra soils.

Plasmids have the potential to transfer genetic traits within bacterial communities and thereby serve as a crucial tool for the rapid adaptation of bacteria in response to changing environmental conditions. Our knowledge of the environmental pool of plasmids (the metaplasmidome) and encoded functions is still limited due to a lack of sufficient extraction methods and tools for identifying and assembling plasmids from metagenomic datasets. Here, we present the first insights into the functional potential of the metaplasmidome of permafrost-affected active-layer soil-an environment with a relatively low biomass and seasonal freeze-thaw cycles that is strongly affected by global warming.

Simple, Reliable, and Time-Efficient Manual Annotation of Bacterial Genomes with MAISEN.

Over the last 15 years, the costs of DNA sequencing have sharply fallen, effectively shifting the costs of DNA analysis from sequencing to bioinformatic curation and storage. A huge number of available DNA sequences (including genomes and metagenomes) resulted in the development of various tools for sequence annotation. While much effort has been invested into the development of automatic annotation pipelines, manual curation of their results is still necessary in order to obtain a reliable and strictly validated data.

The Bad and the Good-Microorganisms in Cultural Heritage Environments-An Update on Biodeterioration and Biotreatment Approaches.

Cultural heritage objects constitute a very diverse environment, inhabited by various bacteria and fungi. The impact of these microorganisms on the degradation of artworks is undeniable, but at the same time, some of them may be applied for the efficient biotreatment of cultural heritage assets. Interventions with microorganisms have been proven to be useful in restoration of artworks, when classical chemical and mechanical methods fail or produce poor or short-term effects.

Multimodal Approach to Assessment of Fecal Microbiota Donors based on Three Complementary Methods.

Methods of stool assessment are mostly focused on next-generation sequencing (NGS) or classical culturing, but only rarely both. We conducted a series of experiments using a multi-method approach to trace the stability of gut microbiota in various donors over time, to find the best method for the proper selection of fecal donors and to find "super-donor" indicators. Ten consecutive stools donated by each of three donors were used for the experiments (30 stools in total).

Genomic Insights Into the Complex: An Update.

Only very recently, has it been proposed that the hitherto existing subtypes (I-VI) should be elevated, each, to a species rank. Consequently, the former subtypes have been denominated as (former type I), (II), (III), (V), and (VI). The present work extends the recently published findings by using a three-pronged computational strategy, based on the alignment fraction-average nucleotide identity, genome-to-genome distance, and core-genome phylogeny, yet essentially independent and much larger sample, and thus delivers a more refined and complete picture of the complex.
