Potential of fungi to produce bioconcrete

RILEM Technical Letters (2020)

Carolina Coelho Martuscelli Célia Maria Gonçalves Soares Nelson Lima Aires Camões

The cracks in concrete reduce their resistance capacity and allow the entry of harmful agents both for their microstructure and for the reinforcements located inside the structure. Several studies have been done to promote sustainable solutions for this problem. The microbiologically induced calcium carbonate precipitation (MICCP) is an alternative to traditionally used methods and a way to reduce the environmental impact of using more cement and polymers. Most of the biocementation studies to fill cracks or to promote bio self-healing on concrete present bacteria as the microorganisms responsible for the CaCO3 induction process. Fungi are potentially better for the biocementation process because they have more biomass and some develop filaments that can be used as microfibers on materials. Thus, the present work proposes the development of a methodology to analyse the potential use of two urease-positive fungi (Penicillium chrysogenum MUM 9743 and Neurospora crassa MUM 9208) to produce bioconcrete. The microstructure and chemical constituents of biocrystals formed due to MICCP were observed under Scanning Electron Microscopy (SEM). SEM showed fungal mycelia as bio-based fiber in bioconcrete and clusters of probable calcite crystals on and around mycelia. Both fungi were able to promote biocimentation of sand.

Mycotoxins production by Aspergillus section Flavi isolated from harvested maize

Célia Maria Gonçalves Soares Armando Venâncio

Mycotoxins are toxic compounds produced by some species of filamentous fungi known to cause serious health problems in humans and animals. In cereals, the key mycotoxigenic fungi in partially dried grains are Aspergillus flavus (aflatoxins), A. ochraceus (ochratoxin A) and some Fusarium species (fumonisins, trichothecenes), being maize is one of the more susceptible commodities. Aflatoxins (AF) produced by Aspergillus section Flavi species and fumonisins produced by Fusarium verticillioides are prominent mycotoxins associated with maize economic losses. Cyclopiazonic acid (CPA) is produced predominantly by A. flavus strains and occurs naturally in a wide variety of crop products as a co-contaminant with AF. In Portugal, maize is one of the most important field crops. In 1999, maize occupied 163 497 ha, with a production of 933 800 tons.
