Enantioselective nitrilases from filamentous fungi. The optical characteristics (chirality) of chemical precursors are important for many fine chemicals. Chiral intermediates are in high demand by the pharmaceutical and agrochemical industries for the preparation of bulk drug intermediates and agricultural products. Nitriles are attractive starting points but their conversion to corresponding amides and carboxylic acids generates significant wastes. Their hydrolysis can be performed under mil ....Enantioselective nitrilases from filamentous fungi. The optical characteristics (chirality) of chemical precursors are important for many fine chemicals. Chiral intermediates are in high demand by the pharmaceutical and agrochemical industries for the preparation of bulk drug intermediates and agricultural products. Nitriles are attractive starting points but their conversion to corresponding amides and carboxylic acids generates significant wastes. Their hydrolysis can be performed under mild conditions by enzymes termed nitrilases. We will work on fungal nitrilases as they present a globally attractive, yet untapped commercial target. The outcome for Applimex will be a suite of biocatalysts specific for the production of key intermediates for drug and agrochemical syntheses.Read moreRead less
Synthesis and assembly of bacterial repeat unit polysaccharides. Bacteria make an enormous range of surface polysaccharides. The complexity was first appreciated as antigenic diversity, but we now have hundreds of chemical structures and perhaps a hundred sequences of their gene clusters, but the number in nature must be many thousands. Our knowledge of gene function is growing but is not keeping up with the discovery of new sequences and structures. The aim is to determine structure and functio ....Synthesis and assembly of bacterial repeat unit polysaccharides. Bacteria make an enormous range of surface polysaccharides.

The benefits are involvement in the growth area of polysaccharide research, with potential for major industrial spin off. Polysaccharides are critical in all organisms as signalling, structural and storage compounds. Bacteria make a wide variety with extensive use of unusual sugars, some with uses from oil emulsifiers to food thickeners. The project is on the enzymes that assemble bacterial polysaccharides. We are world leaders in genetics of the gene clusters especially synthesis of the unusual sugars. We now aim to fill a major gap by determining which enzymes make which bonds, leading to options for new gene combinations and novel structures. We have a lead in research in this area and Australia gains if we maintain that lead.Read moreRead less
Genetic modification and lyophilisation of microorganisms for the generation of bacteriological internal quality controls. The development of internal quality control micro-organisms in precise numbers is necessary for the evolution of standard methodology in microbiology, which until now, remains obsolete, because it relies on inaccurate methods to produce quantitative and qualitative results.

The development of internal quality control micro-organisms in precise numbers is necessary for the evolution of standard methodology in microbiology, which until now, remains obsolete, because it relies on inaccurate methods to produce quantitative and qualitative results. The research described here is largely based on molecular techniques to genetically tag micro-organisms with fluorescent proteins and pigment producing enzymes, and on the manipulation of growth and storage conditions to maximize the survival of micro-organisms during lyophilisation. Successful completion and application of the proposed project through existing patents owned by BTF, will revolutionise the way microbiological tests are performed worldwide.Read moreRead less
Role of the proteasome in eradication of misfolded proteins in fungal cell factories. Filamentous fungi contribute to the well being of modern society as surrogate hosts for the synthesis of vaccines, hormones and enzymes for their application to health, agriculture, industry and the environment.

Filamentous fungi contribute to the well being of modern society as surrogate hosts for the synthesis of vaccines, hormones and enzymes for their application to health, agriculture, industry and the environment. However, attempts to express foreign proteins to the full potential of a given system have been disappointing. It is vital to understand unexplored molecular and physiological factors such as protein quality control in the cell to take advantage of the global opportunities that recombinant gene expression indisputably offers in the form of unrestricted supply of proteins of social and economic value. The project will create novel IP and licensing opportunities for Australia.Read moreRead less
