Project description:To determine whether and how warming affects the functional capacities of the active microbial communities, GeoChip 5.0 microarray was used. Briefly, four fractions of each 13C-straw sample were selected and regarded as representative for the active bacterial community if 16S rRNA genes of the corresponding 12C-straw samples at the same density fraction were close to zero.
Project description:We have studied the physiological response of the fungus Aspergillus niger when exposed to wheat straw as a model lignocellulosic substrate. Using RNA-sequencing we showed that, 24 hours after exposure to straw, gene expression of known plant cell wall degrading enzymes represents a huge investment for the cells (about 20 % of the total mRNA). Our results also uncovered new esterases and surface interacting proteins that might form part of the fungal degradative arsenal. We also show that antisense transcripts are abundant and that their expression can be regulated by conditions.

Triplicate samples of A. niger N402 taken at each of three timepoints: After 48 h growth in minimal media with Glucose as sole carbon source, After transfer to Wheat Straw media for 24 h and 5 h after after the exogenous addition of glucose to the wheat starw media.
Project description:The fungal RNA from 6 different conditions, especially one that mimics the plant environment (Barley Straw Agar –BSagar) was also sequenced to help in one hand the annotation and in other hand to uncover putative gene of interest that might be involved in the pathogenicity or the fungicide resistances for example.
Project description:The white rot fungi Pleurotus ostreatus was studied for its potential as a biological pretreatment agent, i.e- its potential for decomposing lignocellulosic biomass. P. ostreatus PC9 was manipulate to either overexpress or eliminate (by gene replacement) the transcriptional regulator CRE1, known to act as a repressor in the process of carbon catabolite repression. The parental PC9 and the two transformants were grown on microcrystalline cellulose and wheat straw (3 replicates each) and the content of the resulted secretomes was analyzed by LC-MS/MS. An extensive range of carbohydrate active enzymes (CAZymes) were affected by the modification of cre1 expression levels. The three fungi revealed also differentiation towards the carbon source used in the growth media.
