Lily WALTER - 2024
Patent application filed on behalf of the University of Guyana
Earthen building materials offer a low-carbon footprint solution for construction, but their poor water resistance is holding back their adoption by the construction industry. The addition of biopolymers can enhance this resistance, but also promotes the growth of mold mycelium, which can impair indoor air quality. However, for applications such as insulation or packaging, the controlled growth of specific mycelia, followed by thermal inactivation, represents a promising approach to creating natural, water-resistant materials that preserve air quality.
Building on this knowledge, Lily Walter's work has explored and demonstrated the potential of thermally inactivated mold mycelium to develop biostabilized earth building materials with high water resistance.

Emeline HOUËL - 2014 et 2022
2014 - French patent FR3025979A1- INSECTICIDAL PROPERTIES OF AN EXTRACT OF SEXTONIA RUBRA, AND ITS COMPONENTS
This patent describes the use of wood extracts from Sextonia rubra, a species found on the Guyana plateau, for their insecticidal properties. These extracts, rich in two bioactive compounds, rubrenolide and rubrynolide, have demonstrated their efficacy in the laboratory against the larvae of Aedes aegypti, a mosquito that carries diseases such as dengue and Zika.
2022 - European patent EP4245139A1 - COMPOSITIONS COMPRISING A BOTANICAL EXTRACT AS INSECTICIDAL AGENT
This second patent concerns the development of a formulation based on extract of hardwood pomace for use in the control of larvae of the Ae. aegypti mosquito, the aim being to enable, on the basis of results obtained under semi-operational conditions, the development of a product that can be used under environmental conditions.
