Microalgae - A renewable source of feed, fuel and nutraceuticals
The Algae Biotechnology Group aims to sustainably produce oil, protein-rich biomass and high-value products from microalgae.
Microalgae can be farmed without competing for arable land and food production using nearly any type of water (fresh, brackish, seawater or nutrient-rich wastewater). We identify local freshwater and marine strains that are efficient producers of lipids, crude protein and neutraceuticals, then optimise these by using adaptive evolution and metabolic engineering. Our lab takes a "Non-GM" approach to strain improvement specialising in aquatic-crop optimisation aimed at providing our industry partners with cost-effective oil, animal feed and neutraceutical products. We also use the small aquatic plant Lemna for water treatment and efficient nutrient recovery from farm effluents
We have developed simple, low-cost technologies for all steps of algae cultivation, harvesting and extraction processes. This enables simple, farm-scale microalgae production, providing algal based products to the neutraceutical, animal feed biodiesel markets. Our technologies are demonstrated on large scale at the UQ Algae Energy Farm. in Pinjarra Hills, Queensland, Australia. Apart from microalgae, the small aquatic plant Lemna is used for water treatment and efficient nutrient recovery from farm effluents.
This demonstration farm unlocks microalgae’s potential as a zero-waste bio-refinery concept, using a range of different microalgae to produce oil for omega-3 fatty acids and biodiesel, as well as protein-rich biomass for food and animal feed. For example, remaining biomass after oil extraction is used for high-value protein extraction or animal feed. The option to combine oil extraction with anaerobic digestion of the remaining biomass enables closing the loop for sustainable nutrient recycling and organic farming.
For our industry partners we offer a 360° approach to algae cultivation, harvesting and extraction. This includes supply of suitable strains, training at the Algae Energy Farm, assistance with farm design, techno-economic analyses for various production scenarios, as well as assistance during farm construction and operation during the first 12 months.
Plant and Microbial Biotechnology
The Plant-Microbe Interactions Group specialises in the discovery of interesting new genes from plants and microorganisms. This team develops disease-resistant plants and identifies novel compounds from microbial communities associated with the rhizosphere of plants.
We use a Functional Genomics approach to study beneficial and parasitic interactions between plants and microbes. Regulation of defence signalling genes can lead to disease resistance. In conjunction with industry we're working on improving crop plants for resistance against fungi, bacteria, viruses and nematodes.

In our microbial community project, functional gene microarrays and next-gen sequencing are used in a metatranscriptomics approach to characterise highly diverse microbial communities associated with plants, capturing microbial activity profiles irrespective of species.
