Plant Biotechnologies

The Plant Biotechnologies research group develops new concepts, products and services based on plant bioprocess engineering approaches, as well as synthetic biology using chassis (micro)organisms and integrative biology. The goal is the valorisation of plant biomass as feedstock of molecules for sustainable industrial products and the green biotech sector.

The research team applies functional genomics approaches to clarify their biosynthetic pathway in planta, as well as heterologous expression of microbial secondary metabolite biosynthetic gene clusters in host organisms combined with a high-throughput mass spectrometry-based biodiscovery metabolomics platform.

MAIN EXPERTISE FIELDS

  • Plant and microbial bioprospecting

Plants and microorganisms produce a wide array of secondary metabolites with biological activities of high interest for the cosmeceutical, nutraceutical, pharmaceutical and agro-chemical industries. The Plant Biotechnologies research group also promotes the valorisation of plant genetic diversity in compliance with access and benefit-sharing (ABS) principles and valorises agro-industrial by-products as a source of commercially relevant molecules. This includes the upcycling of brewery residual biomass, apple/grape pomaces to a source of bio-active compounds.

  • Plant cultures

Plants are cultivated both in vitro, in soil and as cell suspension cultures to characterise them from the molecular point of view. Among the research activities of the group, there is the study and valorisation of multi-purpose and underutilised crops, such as Cannabis sativa and Urtica dioica, as sources of both fibres and phytochemicals, as well as the cultivation of plant cell cultures, for example apple varieties, for the production of high added-value molecules and the biodiscovery of bioactive molecules of microbial origin for plant protection applications.

  • Synthetic biology and bioprocess engineering

Metabolic engineering combined with comprehensive chemical characterisation techniques are used to develop chassis organisms, plants and plant cell cultures for the sustainable production of known and novel high-value molecules with new or superior biological activities. Once a cell line is established at the laboratory scale, the Plant Biotechnologies research group develops bioprocess engineering approaches for upscaling.
