Fed-batch fermentation of Tuber melanosporum for the hyperproduction of mycelia and bioactive Tuber polysaccharides

open access: yesBioresource Technology, 2009
For the first time, a fed-batch fermentation process of Tuber melanosporum was developed for the efficient production of bioactive mycelia and Tuber polysaccharides. Each 1.67 g/L of peptone and 8.33 g/L of yeast extract were added on day 3, 6, and 9, respectively, and sucrose was fed to maintain its concentration around 35-5 g/L when its residual ...

Soil Characteristics of Tuber melanosporum Habitat

open access: yes, 2016
Tuber melanosporum belongs to the genus Tuber that only includes mycorrhizal fungi living and fruiting underground within the soil environment. T. melanosporum prefers sites in ridges or slopes, where water does not accumulate, and fractured parent materials where water can drain well.

Persistence of Tuber melanosporum in truffle orchards in North Carolina, USA

Mycorrhiza, 2020
A survey was conducted to determine the persistence of mycorrhization by Tuber melanosporum in truffle orchards established with European and American species of oak and common hazel trees in North Carolina. The trees had reportedly been inoculated and colonized by T. melanosporum prior to planting. Root samples were collected from 95 trees among seven

Self/nonself recognition in Tuber melanosporum is not mediated by a heterokaryon incompatibility system

open access: yesFungal Biology, 2012
Vegetative incompatibility is a widespread phenomenon in filamentous ascomycetes, which limits formation of viable heterokaryons. Whether this phenomenon plays a role in maintaining the homokaryotic state of the hyphae during the vegetative growth of Tuber spp.

Is Tuber melanosporum colonizing the roots of herbaceous, nonectomycorrhizal plants?

open access: yesFungal Ecology, 2018
The ectomycorrhizal Tuber melanosporum forms edible fruit-bodies after mating between two haploid parents: a maternal individual, which feeds the fruit-body and colonizes surrounding ectomycorrhizas, and a paternal one hitherto undetected around fruit-bodies. Several other aspects of T.

Odour composition of the Tuber melanosporum complex

Mycological Research, 1990
Odour composition of some taxa related to Tuber melanosporum has been studied by gas chromatography coupled to a mass spectrometer (GC-MS). Although qualitative differences have been observed, the relative amounts of substances present may be more significant for their chemical taxonomy. A concept of the Tuber odour according to its ecological function

Identification and quantification of Tuber melanosporum Vitt. sterols

Steroids, 1996
The sterol composition of Tuber melanosporum was examined by medium-pressure liquid and high-performance liquid chromatography, nuclear magnetic resonance spectroscopy, and mass spectrometry. Ergosterol (ergosta-5,7,22-trienol) and brassicasterol (ergosta-5,22-dienol) were identified as the major components (90%).

The Black Truffles Tuber melanosporum and Tuber indicum

2016
The European species Tuber melanosporum and the Asian species T. indicum are phylogenetically and morphologically very close. T. indicum is formed by a complex of cryptic species or ecotypes spread from India to Japan, while T. melanosporum is a well-defined species localised in South of Europe. T. melanosporum has been harvested and consumed in Europe
