Article Synopsis
  • This study focused on selecting endophytic fungi to produce the enzyme L-asparaginase, using cacti as a substrate for optimization.
  • Seventeen endophytes were tested, with Diaporthe ueckerae URM 8321 emerging as the best producer, especially using flours from Opuntia ficus-indica and Nopalea cochenillifera.
  • The research identified optimal conditions for enzyme production, achieving a 46.11% increase in L-asparaginase output at an initial pH of 4.0, with a production time of 120 hours.

In this study, we examined endophytic fungi in leaves of Mandevilla catimbauensis, an endemic plant species found in the Brazilian dry forest (Caatinga), and endophytic fungi's potential to produce L-asparaginase (L-ASNase). In total, 66 endophytes were isolated, and the leaf-fragment colonisation rate was 11.78%.

Aims: The aim of this study was to find new eukaryotic sources of the l-asparaginase (l-ASNase), since the prokaryotic sources of the enzyme are well-reported as causing allergic hypersensitivity reactions in a significant number of patients. This report describes screening for l-ASNase production by filamentous fungi isolated from the Brazilian Caatinga, and the optimization of fermentation parameters to increase fungal growth and improve yield in the production of l-ASNase.

Methods And Results: Thirty-two filamentous fungi were investigated in this study.

This study was conducted to report the richness of endophytic Penicillium and Talaromyces species isolated from Tillandsia catimbauensis, a bromeliad endemic in the Brazilian tropical dry forest (Caatinga), to verify their ability to produce the enzyme L-asparaginase and to partially optimise the production of biomass and L-asparaginase of the best enzyme producer. A total of 184 endophytes were isolated, of which 52 (29%) were identified through morphological and phylogenetic analysis using β-tubulin sequences into nine putative species, four in Penicillium and five in Talaromyces. Talaromyces diversus and T.
