Forms for growing mycelium-based biocomposite test specimens
<p><span>Forms for growing mycelium-based biocomposite test specimens are provided in two variants – with openings for more access to air and without the openings. The forms are intended for the production of cube specimens with a side length of 50 mm. The drawings are provided in two different formats and are intended for laser CNC cutting of plexiglass.</span></p>
Modelling of excitation propagation on computer models of insoles colonised by fungal mycelium. Videos and potential difference recordings.
<p>We used an artistic image of the mycelium network projected onto a $364 \times 985$ nodes grid. <br> The original image $M=(m_{ij})_{1 \leq j \leq n_i, 1 \leq j \leq n_j}$, $m_{ij} \in \{ r_{ij}, g_{ij}, b_{ij} \}$, where $n_i=364$ and $n_j=985$, and $1 \leq r, g, b \leq 255$, was converted to a conductive matrix $C=(m_{ij})_{1 \leq i,j \leq n}$ derived from the image as follows: $m_{ij}=1$ if $r_{ij}>170$, $g_{ij}>170$ and $b_{ij}<200$; a dilution operation was applied to $C$. </p> <p>FitzHugh-Nagumo (FHN) equations is a qualitative approximation of the Hodgkin-Huxley model of electrical activity of living cells:<br> \begin{eqnarray}<br> \frac{\partial v}{\partial t} & = & c_1 u (u-a) (1-u) - c_2 u v + I + D_u \nabla^2 \\<br> \frac{\partial v}{\partial t} & = & b (u - v),<br> \end{eqnarray}<br> where $u$ is a value of a trans-membrane potential, $v$ a variable accountable for a total slow ionic current, or a recovery variable responsible for a slow negative feedback, $I$ {is} a value of an external stimulation current. The current through intra-cellular spaces is approximated by<br> $D_u \nabla^2$, where $D_u$ is a conductance. The term $D_u \nabla^2 u$ governs a passive spread of the current. The terms $c_2 u (u-a) (1-u)$ and $b (u - v)$ describe the ionic currents. The term $u (u-a) (1-u)$ has two stable fixed points $u=0$ and $u=1$ and one unstable point $u=a$, where $a$ is a threshold of an excitation.</p> <p>We integrated the system using the Euler method with the five-node Laplace operator, a time step $\Delta t=0.015$ and a grid point spacing $\Delta x = 2$, while other parameters were $D_u=1$, $a=0.13$, $b=0.013$, $c_1=0.26$. We controlled excitability of the medium by varying $c_2$ from 0.05 (fully excitable) to 0.015 (non excitable). Boundaries are considered to be impermeable: $\partial u/\partial \mathbf{n}=0$, where $\mathbf{n}$ is a vector normal to the boundary. </p> <p>To record dynamics of excitation in the network, as if in laboratory experiments, we simulated electrodes by calculating a potential $p^t_x$ at an electrode location $x$ as $p_x = \sum_{y: |x-y|<2} (u_x - v_x)$. Configuration of electrodes $1, \cdots, 16$ is shown in Fig.~\ref{fig:mycelium}c. Time-lapse snapshots provided in the paper were recorded at every 100\textsuperscript{th} time step, and we display sites with $u >0.04$; videos and figures were produced by saving a frame of the simulation every 100\textsuperscript{th} step of the numerical integration and assembling the saved frames into the video with a play rate of 30 fps. </p> <p>Insole_01: Excitation started at electrode E2</p> <p>Insole_10: Excitation started at electrode E1</p> <p>Insole_11: Excitation started at electrodes E1 and E2</p> <p> </p>

More soil organic carbon is sequestered through the mycelium-pathway than through the root-pathway under nitrogen enrichment in an alpine forest
<p><span>Plant roots and associated mycorrhizae exert a large influence on soil carbon (C) cycling. Yet, little was known whether and how roots and </span><span>ectomycorrhizal</span><span> extraradical mycelia differentially contribute to soil organic C (SOC) accumulation in alpine forests under increasing nitrogen (N) deposition. Using ingrowth cores, the relative contributions of the root-pathway (RP) (i.e., roots and rhizosphere processes) and mycelium-pathway (MP) (i.e., extraradical mycelia and hyphosphere processes) to SOC accumulation were distinguished and quantified in an ectomycorrhizal-dominated forest receiving chronic N addition (25 kg N ha<sup>-1</sup> yr<sup>-1</sup>). Under the non-N addition, the RP facilitated SOC accumulation, while the MP reduced SOC accumulation. Nitrogen addition enhanced the positive effect of RP on SOC accumulation from +18.02 mg C g<sup>-1</sup> to +20.55 mg C g<sup>-1</sup> but counteracted the negative effect of MP on SOC accumulation from -5.62 mg C g<sup>-1</sup> to -0.57 mg C g<sup>-1</sup>, as compared to the non-N addition. Compared to the non-N addition, the N-induced SOC accumulation was 1.62~2.21 mg C g<sup>-1</sup> and 3.23~4.74 mg C g<sup>-1</sup>, in the RP and the MP, respectively. The greater contribution of MP to SOC accumulation was mainly attributed to the higher microbial C pump (MCP) efficacy (the proportion of</span><span> increased microbial residual C to the increased SOC under N addition) in the MP (72.5%) relative to the RP (57%). The higher MCP efficacy in the MP was mainly associated with the higher fungal metabolic activity (i.e., the greater fungal biomass and N-acetyl glucosidase activity) and greater binding efficiency of fungal residual C to mineral surfaces than those of RP. Collectively, our findings highlight the indispensable role of mycelia and hyphosphere processes in the formation and accumulation of stable SOC in the context of increasing N deposition.</span></p>
Percentage distribution of plant-fixed carbon in orchid shoots and roots, protocorms, and mycorrhizal fungal mycelium and amount (total and concentration) of carbon transferred to protocorms and mycorrhizal fungal mycelium by green orchids in each experimental microcosm
<p> The minute 'dust seeds' of some terrestrial orchids preferentially germinate and develop as mycoheterotrophic protocorms near conspecific adult plants. In this paper we tested the hypothesis that mycorrhizal mycelial connections provide a direct pathway for transfer of recent photosynthate from conspecific green orchids to achlorophyllous protocorms. Mycelial networks of <em>Ceratobasidium cornigerum </em>connecting green <em>Dactylorhiza fuchsii</em> plants with developing achlorophyllous protocorms of the same species were established on oatmeal or water agar before the shoots of green plants were exposed to <sup>14</sup>CO<sub>2</sub>. After incubation for 48 hours, the pattern of distribution of fixed carbon was visualised in intact entire autotrophic/protocorm systems using digital autoradiography and quantified in protocorms by liquid scintillation counting. The data presented here represent the percentage distribution of the <sup>14</sup>C fixed by the orchids in our experimental systems to plant shoots, roots, protocorms and the mycorrhizal mycelium. We also show the total amount of <sup>14</sup>C present in plant shoots and protocorms when grown in each of the three media tested (100% water agar, 100% oatmeal agar, and 50:50 water: oatmeal agar). We also show the amount of carbon (total and concentration) transferred from green orchids to protocorms and mycorrhizal mycelium in each microcosm across the three media treatments.</p>
Tensile strength of Ganoderma pure mycelium - raw data
<p>The dataset consists of tensile strength values of pure mycelium of <em>Ganoderma lingzhi</em> and <em>Ganoderma sessile</em> produced using liquid state fermentation. The substrate for liquid state fermentation was supplemented with 0,5% of lignin and 2% of lignin (reference was 0% lignin). Raw data from universal testing machine are also provided. Another variant is a modification of obtained mycelium leather with glycerol treatment (immersion of samples in 20% glycerol solution for 24 hours).</p>
