Project description:These biofilms were established from saliva samples as described in Edlund et al. 2013 (Microbiome, doi:10.1186/2049-2618-1-25). After starving the biofilms in minimal medium anaerobiaclly glucose was added to the cultures. Samples for metatranscriptomics and metabolomics were collected in parallel at pH 7 (prior to glucose amendment), pH 4.2 (6 hours after glucose amendment) and pH 5.2 (9 hours after pH amendment). Secreted small molecules were extracted from biofilms (cells were not lysed) at the differnet pH stages.

Project description:Trichoderma harzianum CECT 2413 expression in liquid basal medium and in the presence of glucose, chitin or tomato plants. Four different experimental conditions were carried out: basal (MS), glucose (MS-G), chitin (MS-Q) and tomato plant (MS-P). Two biological replicates were analyzed by microarray for each experimental condition. Three independent cultures of mycelium were pooled for each biological replicate.

Project description:Within the mouth bacteria are starved of saccharides as their main nutrient source between meals and it is unclear what drives their metabolism. Previously oral in vitro biofilms grown in saliva have shown proteolytic degradation of salivary proteins and increased extracellular proline. Although arginine and glucose have been shown before to have an effect on oral biofilm growth and activity, there is limited evidence for proline. Nuclear magnetic resonance (NMR) spectroscopy was used to identify extracellular metabolites produced by bacteria in oral biofilms grown on hydroxyapatite discs. Biofilms were inoculated with whole mouth saliva and then grown for 7 days using sterilised whole mouth saliva supplemented with proline, arginine and glucose as a growth-medium. Overall proline had a beneficial effect on biofilm growth – with significantly fewer dead bacteria present by biomass and surface area of the biofilms (p <0.05). Where arginine and glucose significantly increased and decreased pH, respectively, the pH of proline supplemented biofilms remained neutral at pH 7.3-7.5. SDS-polyacrylamide gel electrophoresis of the spent saliva from proline and arginine supplemented biofilms showed inhibition of salivary protein degradation of immature biofilms. NMR analysis of the spent saliva revealed that proline supplemented biofilms were metabolically similar to unsupplemented biofilms, but these biofilms actively metabolised proline to 5-aminopentanoate, butyrate and propionate, and actively utilised glycine. This study shows that in a nutrient limited environment, proline has a beneficial effect on in vitro oral biofilms grown from a saliva inoculum.

Project description:Protein extracts of Saccharomyces cerevisiae CEN.PK113-7D cultivated in chemostats under different conditions. Representative samples containing aliquots of all conditions were spiked with UPS2 standard (Sigma) to estimate absolute values in fmol. The conditions for Saccharomyces cerevisiae CEN.PK113-7D are: T2- Standard condition : 30°C, pH 5.5 T3- High temperature: 36°C, pH 5.5 T4- Low pH: 30°C, pH 3.5 T5- Osmotic stress : 30°C, pH 5.5, 1M KCl T6- Anaerobic condition Furthermore, representative samples pooling aliquots of each condition are indicated as "bulk" samples. These samples were spiked with UPS proteins. A validation step was carried out by spiking 4 external proteins at known concentrations within the yeast and UPS proteins mixture

Project description:Alkaline pH stress invokes in S. cerevisiae a potent and fast transcriptional response that includes many genes repressed by glucose. Certain mutants in the glucose-sensing and response pathways, such as those lacking the Snf1 kinase, are sensitive to alkalinization. We show that addition of glucose to the medium improves growth of wild type cells at high pH, fully abolish the snf1 alkali-sensitive phenotype and attenuates high pH-induced Snf1 phosphorylation at Thr210. The elm1 mutant, lacking one of the three upstream Snf1 kinases (tos3, elm1 and sak1), is markedly alkali sensitive, whereas the phenotype of the tos3 elm1 sak1 strain is even stronger than that of snf1 cells and it is not fully rescued by glucose supplementation. DNA microarray analysis reveals that about 75% of genes induced at short term by high pH are also induced by glucose scarcity. Snf1 mediates, in full or in part, the activation of a significant subset (38%) of short-term alkali-induced genes, including those coding high-affinity hexose transporters and phosphorylating enzymes. Induction of genes encoding enzymes involved in glycogen (but not trehalose) metabolism is largely dependent of the presence of Snf1. Therefore, the function of Snf1 in adaptation to glucose scarcity appears crucial for alkaline pH tolerance. Incorporation of micromolar amounts of iron and copper to a glucose-supplemented medium result in an additive effect and allows near normal growth at high pH, thus indicating that these three nutrients are key limiting factors for growth in an alkaline environment.

Project description:RNA-seq libraries were constructed for three samples, including (I) ΔURA3 strain grown in SD medium containing 2% w/v glucose(pH=5.0);(II)ΔURA3 strain grown in SD medium containing 2%w/v glucose and 2% w/v succinic acid(pH=5.0);(III)ΔURA3 strain grown in SD medium containing 2% w/v succinic acid(pH=5.0). For preparation of RNA samples, ΔURA3 cells grown overnight were inoculated into 50 ml liquid Synthetic Dextrose (SD) medium with the initial inoculation amount of OD600= 0.1, and cultured for 24 hours to the logarithmic growth phase (OD600= 2-3). The cells were collected by centrifugation at 6000g for 5 minutes. After washing twice with phosphate buffer saline (PBS), they were inoculated into new 50 mL SD medium containing carbon sources of different combinations of glucose and succinic acid .The pH of the culture sample is adjusted to 5.0 with NaOH. After flask culturing at 30°C and 250 rpm for an additional three hours, the yeast cells were collected by centrifugation for total RNA isolation and Illumina RNA-seq library construction. Total RNA for samples were isolated using TRIzol reagent (Invitrogen, Grand Island, USA), then used for high-throughput RNA sequencing. The 150-nt paired-end RNA-seq libraries were generated commercially at Novogene Biotechnology Co. Ltd (Tianjin, China) by using Illumina’s Hiseq X Ten platform (Illumina, San Diego, USA). Each sample contains two biological replicates.

Project description:Biofilms are surface-adhered bacterial communities encased in an extracellular matrix composed of polysaccharides, proteins, and extracelluar (e)DNA, with eDNA being required for the formation and integrity of biofilms. Here we demonstrate that the spatial and temporal release of eDNA is regulated by BfmR, a regulator essential for Pseudomonas aeruginosa biofilm development. The expression of bfmR coincided with localized cell death and DNA release, with high eDNA concentrations localized to the outer part of microcolonies in the form of a ring and as a cap on small clusters. Additionally, eDNA release and cell lysis increased significantly following bfmR inactivation. Genome-wide transcriptional profiling indicated that bfmR was required for repression of genes associated with bacteriophage assembly and bacteriophage-mediated lysis. In order to determine which of these genes were directly regulated by BfmR, we utilized chromatin immunoprecipitation (ChIP) analysis to identify the promoter of PA0691, termed here phdA, encoding a previously undescribed homologue of the prevent-host-death (Phd) family of proteins. Lack of phdA expression coincided with impaired biofilm development, increased cell death and bacteriophage release, a phenotype comparable to ΔbfmR. Expression of phdA in ΔbfmR biofilms restored eDNA release, cell lysis, release of bacteriophages, and biofilm formation to wild type levels. Moreover, overexpression of phdA rendered P. aeruginosa resistant to lysis mediated by superinfective bacteriophage Pf4 which was only detected in biofilms. The expression of bfmR was stimulated by conditions resulting in membrane perturbation and cell lysis. Thus, we propose that BfmR regulates biofilm development by controlling bacteriophage-mediated lysis and thus, cell death and eDNA release, via PhdA.
