CRISPR/Cas9 mediated gene editing of transcription factor ACE1 for enhanced cellulase production in thermophilic fungus Rasamsonia emersonii

Author(s): Singh V; Raheja Y; Basotra N; Sharma G; Tsang A; Chadha BS;

Background: The filamentous fungus Rasamsonia emersonii has immense potential to produce biorefinery relevant thermostable cellulase and hemicellulase enzymes using lignocellulosic biomass. Previously in our lab, a hyper-cellulase producing strain of R. eme ...

CRAPS: Chromosomal-Repair-Assisted Pathway Shuffling in Yeast

Author(s): Dykstra CB; Pyne ME; Martin VJJ;

A fundamental challenge of metabolic engineering involves assembling and screening vast combinations of orthologous enzymes across a multistep biochemical pathway. Current pathway assembly workflows involve combining genetic parts ex vivo and assembling one ...

Rapid, scalable, combinatorial genome engineering by marker-less enrichment and recombination of genetically engineered loci in yeast

Author(s): Abdullah M; Greco BM; Laurent JM; Garge RK; Boutz DR; Vandeloo M; Marcotte EM; Kachroo AH; ...

A major challenge to rationally building multi-gene processes in yeast arises due to the combinatorics of combining all of the individual edits into the same strain. Here, we present a precise and ...

The MyLo CRISPR-Cas9 Toolkit: A Markerless Yeast Localization and Overexpression CRISPR-Cas9 Toolkit

Author(s): Bean BDM; Whiteway M; Martin VJJ;

The genetic tractability of the yeast Saccharomyces cerevisiae has made it a key model organism for basic research and a target for metabolic engineering. To streamline the introduction of tagged genes and compartmental markers with powerful CRISPR-Cas9-bas ...

The chimeric GaaR-XlnR transcription factor induces pectinolytic activities in the presence of D-xylose in Aspergillus niger

Author(s): Kun RS; Garrigues S; Di Falco M; Tsang A; de Vries RP;

Aspergillus niger is a filamentous fungus well known for its ability to produce a wide variety of pectinolytic enzymes, which have many applications in the industry. The transcriptional activator GaaR is induced by 2-keto-3-deoxy-L-galactonate, a compound d ...

Identification of a Novel Biosynthetic Gene Cluster in Aspergillus niger Using Comparative Genomics

Author(s): Evdokias G; Semper C; Mora-Ochomogo M; Di Falco M; Nguyen TTM; Savchenko A; Tsang A; Benoit-Gelber I; ...

Previously, DNA microarrays analysis showed that, in co-culture with Bacillus subtilis, a biosynthetic gene cluster anchored with a nonribosomal peptides synthetase of Aspergillus niger is downregu ...
