Project description:The biodegradation of lignite (brown coal) by microorganisms has the potential for bioremediation of contaminated mining sites and to generate alternative ways to valorize lignite, such as by producing humic acids or building block chemicals. Previously, a lignite-degrading strain of Trichoderma was isolated, but the genomic and transcriptomic basis of its lignite-degrading ability remained unknown. Here we report that the sequenced genome of the T. cf. simile WF8 strain encoded for enzymes with roles in the degradation of lignite, and potentially tolerance to lignite-breakdown products. There was only a small number of annotated unique genes in the T. cf. simile WF8 genome compared to other fungi, and likely the expression of gene families shared with other fungi is a key factor in lignite biosolubilization by T. cf. simile. The transcriptomes were analyzed of T. cf. simile cultured at two time-points with the lignite-breakdown model compounds 4-phenoxybenzoic acid (which was growth inhibitory), and phenetole and 9-10-dibutoxyanthracene (neither of which inhibited growth), and showed ~20% of genes up-regulated by one or more of these compounds. The analysis highlights candidates for characterization and engineering enzyme over-expressing T. cf. simile strains with potentially improved degradation capacity, e.g., laccases and peroxidases, or tolerance and catabolism of breakdown products, e.g., cytochrome P450s, and ring cleavage dioxygenases.

Project description:Kharchia local is an Indian tall landrace wheat cultivar. It is native to sodic-saline soils of Kharchia tehsil of the Pali district of Rajasthan, and is a line developed from selections from farmer's fields. It is the most salt tolerant wheat genotype found in India. No systematic study has been carried out in this direction so far. The gaps in understanding of the mechanism underlying salt tolerance limit our ability to improve the salt tolerance in other crop plants. Transcriptome analysis of Kharchia Local under salt stress will provide the insight into the genes involved in salinity tolerance.

Project description:The pyrite mine of Lousal, Grândola, Portugal, was discovered in 1882 and extensively exploited from 1900 until its closure in 1988 when the mining ores were not viable economically. Aiming at becoming a cultural-touristic center, the mining area was rehabilitated raising a Mining Museum and a Science Centre along with the reopening of a mining gallery for public access. In recent times, aerobiological studies on subterranean environments such as caves, mines and archeological necropolis revealed to be an important source of novel bacteria, from which their biotechnological potential are under study. Here we present a Pseudomonas sp. isolated from the mine air with potential secondary metabolite biosynthesis, resistance to antibiotics and virulence factors.
