Penicillium and Talaromyces endophytes from Tillandsia catimbauensis, a bromeliad endemic in the Brazilian tropical dry forest, and their potential for l-asparaginase production

Fungal endophyte diversity in the leaves of the medicinal plant Myracrodruon urundeuva in a Brazilian dry tropical forest and their capacity to produce L-asparaginase

“…For example, Krishnapura & Belur (2016) reported that T. pinophilus isolated as an endophyte from the rhizomes of Curcuma amada was the best producer of L-asparaginase, exhibiting up to 98% of total activity. Similar results were obtained by Silva et al (2018), who related the L-asparaginase activity from endophytes isolated of the bromeliad Tillandsia catimbauensis. The authors verified Talaromyces cf.…”

“…For L-asparaginase production, 20 endophytes belonging to nine genera (7 isolates from caatinga and 13 from brejo de altitude) were randomly selected. L-asparaginase was produced and modified as per the studies by Loureiro et al (2012) and Silva et al (2018), respectively. Briefly, the liquid medium Czapek Dox's (Saxena & Sinha 1981), as modified by Gulati et al (1997), was used in the pre-fermentation step; it contained (in g/L): glucose (14.0), L-asparagine (10.0), KH2PO4 (1.52), KCl (0.52), MgSO4•7H2O (0.52), CuNO3•3H2O (0.01), ZnSO4•7H2O (0.01), FeSO4•7H2O (0.01), and (NH₄)₂SO₄ (2.0).…”

First report of Penicillium brasilianum Bat., P. cluniae Quintan., and P. echinulonalgiovense S. Abe ex Houbraken & R.N. Barbosa (Eurotiales, Aspergillaceae) as endophytes from a bromeliad in the Caatinga dry forest in Brazil

“…These fungi are of great importance in the fields of medicine, agriculture, production of industrially important enzymes, decomposition of organic matter such as food, and indoor environments (Houbraken et al 2014). They are also often referred to as endophytes in several ecosystems, including tropical dry forests (e.g., Bezerra et al 2015;Silva et al 2018;Pádua et al 2019).…”

“…Some studies have verified the richness of endophytes associated with bromeliads in Brazil (e.g., Landell et al 2006;Felix et al 2017;Bezerra et al 2018); however, until now, only one study validated the presence of endophytic fungi associated with bromeliads in the Caatinga forest (Silva et al 2018), but without a full identification of strains at the species level.…”

“…The aim of the present study was to identify endophytic Penicillium isolates from Silva et al (2018), belonging to the section Lanata-Divaricata, by combining morphological data and sequences of two genes, β-tubulin (BenA) and calmodulin (CaM). In this paper, we highlight the occurrence Penicillium brasilianum Batista, P. cluniae Quintanilla, and P. echinulonalgiovense S. Abe ex Houbraken & R.N.…”
