BackgroundAs a metal-enriched edible fungus,Ganoderma lucidumis capable of adsorbing manganese effectively. And the manganese ion is demonstrated to play an important role in the synthesis of manganese peroxidase (Mnp) and other physiological activities duringG. lucidumgrowth. Recently, the influence of manganese on the metabolites ofG. lucidumfruiting bodies can be revealed through metabonomics technique.MethodsIn this study, we uncovered the changes between the control and 200 mg/kg Mn-treated fruiting bodies with liquid chromatography coupled to mass spectrometry (LC-MS).ResultsThe mycelial growth rate, dry yield, Mnp activity , total polysaccharide content, triterpenoid content, and total manganese content in the mature fruiting bodies ofG. lucidumchanged between the control and different Mn-treated groups. Based on LC-MS method, a total of 16 significantly different metabolites were obtained and identified, among which, five presented significantly down-regulated and 11 up-regulated in Mn-treated samples. The metabolites chavicol and palmitoylethanolamide were particularly significantly up-regulated, and were found the strong promotion relationship. Dependent on the MetPA database, four KEGG pathways were detected and glycerophospholipid metabolism was most impacted, in which, choline was involved in.DiscussionThe added manganese ion in the substrate enhanced Mnp activities, and consequently promoted the mycelial growth, yield , metabolites in the fruiting bodies including triterpenoids, total manganese, chavicol, etc. Our finding can provide a theoretical reference to regulation of manganese on the physiological metabolism ofG. lucidum.

Black poplar mushroom, Agrocybe cylindracea deserves special attention, due to its medicinal properties. Water and alcohol extracts from fruiting bodies of the fungus have an anti-oxidant, anti-cancer, anti-fungal, cholesterol and triglycerides blood level lowering abilities. This mushroom is rich in proteins and vitamins, mineral elements and low in fat. The aim of the experiments was to determine effect of a substrate supplementation with CaCO3 on mycelial growth, yield, morphological features and storability of fruiting bodies of four strains of A. cylindracea (DC.) Marie. The amount of additive to sawdust substrate affects rate of mycelial growth and yield of investigated strains. A. cylindracea mycelial growth was not affected by addition of CaCO3 to substrate, however a significant effect of this additive was found on yield, which was the highest with CaCO3 addition in an amount of 8 g/100 g of substrate. Carpophores characterized with the largest caps diameter, and the largest individual mass obtained of substrate enriched with CaCO3 addition of 8 g/100 g of substrate. In addition, it was found that supplementation with CaCO3 affect storability of A. cylindracea. The lowest weight loss of fruiting bodies after 3 and 7 days of storage was found with addition of CaCO3 to substrate in an amount of 4 g/100 g of substrate.

ABSTRACT: This study evaluated the use of immersion water from peach palm leaves (PPLDA) as a component of the culture medium for the maintenance of Pleurotus spp. and the use of agricultural waste, peach palm leaves, as inoculum support for the fungi. The performance of the inoculum based on peach palm leaves (PPL) for the production of Pleurotus spp. fruiting bodies was compared with that using wheat grains (WG) as inoculum support. PPLDA culture medium (immersion water of peach palm leaves, dextrose, and agar) showed a lower radial velocity of mycelial growth for both fungi than that obtained with the culture medium WDA (wheat extract, dextrose and agar), commonly used as maintenance medium for Pleurotus spp. However, the type of inoculum support does not significantly influence the linear velocity of P. ostreatus mycelial growth, reaching 6.71 mm/day on wheat grains and 6.18 mm/day on peach palm leaves. Thus, when the inoculum based on peach palm leaves is utilized, the immersion water used for preparing this support can be used for preparing the PPLDA maintenance culture medium, diminishing the production costs of Pleurotus mushrooms. Data also showed that when Pleurotus sajor-caju was cultivated on peach palm leaves, using PPL as inoculum support, the fruiting bodies production parameters (Y = 47%, BE = 3% and Pr = 0.2 g/day) did not differ from that obtained using WG.

Sixteen lanostane-type triterpeneoids were isolated from the fruiting bodies of wild Ganoderma lucidum and G. multipileum. The new structures 3 S,24 S,25,26-tetrahydroxy-5α-lanost-8-en-11-one (1) and ganodermanondiol 24,25-acetonide (10) were elucidated by means of spectroscopic data and Mosher's experiments. Lanosta-7,9(11)-dien-3β-ol (9) strongly inhibited α-glucosidase with the IC50 values of 198.8 μM in compared with acarbose (IC50 712.4 μM).
