Extracellular Enzymatic Activity of <i>Tuber maculatum</i> and <i>Tuber aestivum</i> Mycelia

Abstract

Truffle mycelia exhibit a complex interaction pattern with host plants and have been extensively studied over the last years as a source of new bioactive compounds. Fungal enzymes possess a wide use in food industry, confectionaries, textiles and leather industries in order to simplify the processing of raw materials. They are often more stable than enzymes derived from other sources. Tuber maculatum and Tuber aestivum mycelia were tested for enzymes production in Petri dishes solid medium conditions. The results showed that Tuber maculatum produced seven extracellular enzymes (amylase, xylanase, laccase, lipase, peroxidase, cellulase and catalase) while Tuber aestivum produced only three enzymes (amylase, peroxidase and catalase).

Potentials of truffles in nutritional and medicinal applications: a review

“…Extracellular enzymes play a role in nutrient acquisition and symbiotic fungus-host interaction helping truffles to penetrate and colonize into roots of the host plants [57]. T. maculatum produced seven extracellular enzymes, including amylase, catalase, cellulase, laccase, lipase, peroxidase, and xylanase; however, T. aestivum produced amylase, catalase, and peroxidase [58,59].…”

In vitro interactions between Bradyrhizobium spp. and Tuber magnatum mycelium

“…Mycelia of different Tuber species have been successfully isolated by many authors and used for a variety of scientific purposes (Ceccaroli et al, 2001 ; Iotti et al, 2002 , 2016 ; Leonardi et al, 2017 ; Li et al, 2012 ; Liu et al, 2009 ; Nadim et al, 2015 ; Poma et al, 1999 ; Saltarelli et al, 2003 ; Sbrana et al, 2002 ; Vahdatzadeh & Splivallo, 2018 ). However, viable and stable mycelial cultures of T. magnatum have been obtained for the first time only by this work, despite the numerous attempts made over the years.…”

Evaluation of Antifungal and Enzymatic Potential of Endophytic Fungi Isolated from Cupressus torulosa D. Don

“…The amylolytic potential of these endophytes may help them to degrade starch which is available when the plant senesces. The isolate KCTS34 was show highest amylase activity with the diameter of 76 mm The Amylase activity was found to be higher with Tuber aestivum than with Tuber maculatum (Nadim et al, 2015). Rhizoctonia sp.…”
