Project description:In this study, we present a follow up investigation on the effects of argon plasma on vegetative growing Bacillus subtilis 168 (see GSE27113). A growth chamber system suitable for low temperature gas plasma treatment of bacteria in liquid medium enabled a first glimpse on the complex cellular response. In order to gain further knowledge, a second kind of plasma treatment was applied and combined proteomic and transcriptomic analyses were used to investigate the specific stress response of B. subtilis cells to treatment with not only argon but also air plasma. Besides similar cellular responses, due to both argon and air plasma treatment, a variety of different responses such as growth retardation and morphological changes were observed. Furthermore, we analyzed the specific response to DNA damages and oxidative stress. The biological findings such as oxidative stress responses were supported by the detection of reactive plasma species by OES and FTIR measurements.

The biological findings such as oxidative stress responses were supported by the detection of reactive plasma species by OES and FTIR measurements. Cells were grown in LB medium. At OD540 of 0.5, air plasma treatment was set for 15 min with a discharge power of 7.4 W. Samples for mircroarray analysis were taken 5 min after the 15 min plasma treatment. Microarray hybridizations were performed with RNA from three biological replicates. The individual samples were labeled with Cy5; a reference pool containing equal amounts of RNA from all samples was labeled with Cy3.

Project description:Transcriptome analysis of Bacillus subtilis in response to physical plasma treatment
| PRJNA137433 | ENA
Project description:In this study, we introduce for the first time a growth chamber system suitable for physical plasma treatment of bacteria in liquid medium. Bacillus subtilis 168 cells were treated with argon plasma in order to investigate their specific stress response usong a proteomic and transcriptomic approach. The treatment with three different discharge voltages revealed not only growth differences, but also clear cellular stress responses. B. subtilis faces severe cell wall stress, which was made visible alsoelectron microscopy, DNA damages and oxidative stress. The biological findings could be supported by the reactive plasma species, found by plasma diagnostics, i.e. optical emission spectroscopy (OES) and Fourier transformed infrared spectroscopy (FTIR).

Project description:Soybeans fermented by Bacillus subtilis BJ3-2 exhibits strong ammonia taste in medium temperature below 37℃ and prominent soy sauce-like aroma moderate temperatures above 45℃. The transcriptome sequencing of Bacillus subtilis BJ3-2 (incubating at 37°C and 45°C) has been completed, screening of differentially expressed genes (DEGs) through data analysis, and analyzing their metabolic pathways, laying a foundation for exploring the regulatory mechanism of soy sauce-like aroma formation.
