No full textEffects of 6 substances of 29 specifically expressed in the pre-simbiotic phase of Tuber borchii Tilia
americana interaction and root extracts obtained in water and ethanol were tested on T. borchii mycelium. Root extracts
increased hyphal branching; this is in agree with data obtained using only endo-mycorhhizal fungi. The tested
substances showed various effects on morphology and features of mycelia. Probably lipophylic substance is present
in root extracts and causes an increase of hyphal branching, wheres the other substances, perhaps except benzothiazol,
do not seem directly involved in the pre-simbiotic interaction

No full textCultivation of edible ectomycorrhizal fungi by in vitro mycorrhizal synthesis
No full textGiomaro, Sisti and Zambonelli discuss the problems encountered in the stady of edible ECM, with major emphasis on truffle. References to root culture suggest a number of promising avenues for research. One of the difficulties encountered in studying species such as Tuber or Cantharellus spp. is that their biology involves interactions with a large number of soil bacteria. Root cultures should prove useful in determining which species are critical for the development of the mycelia as well as fruit bodies. Understanding signalling, biochemical exchanges, and mutualist physiology should be improved using this approach. The maintenance and production of inoculums should also benefit fron monoxenic culture
Valutazione delle prestazioni analitiche del metodo Access(R) Hybritech(R) PSA mediante l’applicazione del protocollo CLSI EP-17A
No full textA Possible Scenario for the Covid-19 Epidemic, Based on the SI(R) Model
No full textMany attempts to build epidemic models of the current Covid-19 epidemic have been made in the recent past. However, only
models postulating permanent immunity have been proposed. In this paper, we propose a SI(R) model in order to forecast the
evolution of the epidemic under the hypothesis of not permanent immunity. This model offers an analytical solution to the
problem of finding possible steady states, providing the following equilibrium values: Susceptible about 17%, Recovered
(including deceased and healed) ranging from 79 to 81%, and Infected ranging from 2 to 4%. However, it is crucial to consider
that the results concerning the recovered, which at first glance are particularly impressive, include the huge proportion of
asymptomatic subjects. On the basis of these considerations, we analyse the situation in the province of Pesaro-Urbino, one of
the main outbreaks of the epidemic in Italy
