Project description:Spirosoma montaniterrae DY10T is an uncharacterized radiation-resistanct bacteria isolated from soil in South Korea. In order to identify the underlying mechanisms involved in UVC-resistance, we generated time-series transcriptome data with UVC radiation and analyzed data with computational methods.
Project description:In order to get insights into the ability of ectomycorrhizal fungi to perceive their biotic environment as well as into the mechanisms of the interactions between ectomycorrhizal fungi and soil bacteria, we analysed the transcriptomic response of the ectomycorrhizal fungus L. bicolor and of two beneficial, and neutral soil bacteria during their interactions in vitro.
Project description:Design: double blind controlled randomized trial with a parallel design and 3 treatment groups Description of subjects: Patients admitted in study centers for colorectal surgery under laporoscopy and/or laparotomy.
Product:
Product 1: BB536 and LA1 (10E9) Product 2: BB536 and LA1 (10E7) Placebo: Maltodextrin Number of patients: enrolled subjects: n=33, ITT data set: n=31, PP data set: n=30
Primary objective:
Colonization (biopsy+stools) of each bacteria for one of the dose at D0 (surgical procedure)
Secondary objectives:
* Influence of the probiotic bacteria on the gut microflora
* Modulation of the immune and inflammatory response
Additional objectives:
* Investigate dose effect on La1 colonization
* Investigate the effect of La1 colonization, treatment without La1 colonization, and absence of treatment and La1 colonization on other bacteria and on immunological parameters
Project description:Bacillus amyloliquefaciens FZB42 is a representative organism for Gram positive soil bacteria associated with plant roots and beneficial to plant growth. It is of immense importance to understand mechanisms of this class of bacteria adapting to rhizosphere. In this work employing differential RNA sequencing (RNA-seq) and Northern blot, we systematically identified transcription start sites of mRNAs as well as non-coding regulatory RNAs in FZB42. The genes regulated at different growth phases and located in polycistronic operons were also identified. A set of genes were re-annotated. In addition, a sRNA named Bas01 was identified to be involved in Bacillus sporulation and biofilm formation. The result we obtained provides valuable data for investigation of Bacillus gene expression and molecular details of rhizobacterial interaction with host plants.
Project description:Some soil bacteria promote plant growth, including Pseudomonas species. With this approach we detected significant changes in Arabidopsis genes related to primary metabolism that were induced by the bacteria.
Project description:Bacteria belonging to phylum Gemmatimonadetes are found in a wide variety of environments and are particularly abundant in soils. To date, only two Gemmatimonadetes strains have been characterized. Here we report the complete genome sequence and methylation pattern of Gemmatirosa kalamazoonensis KBS708 (ATCC BAA-2150; NCCB 100411), the first characterized Gemmatimondetes strain isolated from soil. Examination of the methylome of Gemmatirosa kalamazoonenis KBS708 using kinetic data from single-molecule, real-time (SMRT) sequencing on the PacBio RS
