“…edodes strongly inhibited conidial germination, with the germination rate of conidia in the presence of the extract being 4.1%. 13) However, the extract of SMS of H. marmoreus did not show antifungal activity in this assay. The germination rate of conidia in distilled water was 91.2%, and in the H. marmoreus SMS extract it was 90.5%.…”

“…The preparation of hot water extracts of SMSs has been described previously. 13) The SMS extract (5 mL) was sprayed on five 16-day-old seedlings in a pot. As a negative control, leaves were sprayed with distilled water, whereas, as a positive control, a BIT (1,1-benzisothiazol-3(H)-one-1,1-dioxide, Wako Pure Chemical Industries, Osaka, Japan) solution (56 mg/L, 20 mL) was added to a pot (50 mL) containing 13-day-old rice seedlings, as described by Nakashita et al (2002).…”

We investigated the effect of treatment with hot water extracts from the spent mushroom substrates (SMSs) of Lentinula edodes and Hypsizygus marmoreus on the resistance of rice leaves to Pyricularia oryzae infection. The spraying of the SMS extracts clearly suppressed the development of lesions caused by Py. oryzae infection. The accumulation of phytoalexins momilactones A and B, oryzalexin A, and sakuranetin was markedly induced by the spraying of extracts. The enhanced expression of defense related genes PR1b and PBZ was also found in leaves sprayed with the extracts. Treatments with the extracts also affected phytohormone levels. The levels of N 6 -(Δ 2 -isopentenyl)adenine and trans-zeatin markedly increased in response to treatment, whereas the levels of salicylic and jasmonic acids were largely unchanged.

M USHROOM farms started to widely establish in Egypt to partially replace animal protein. The type Pleurotus ostreatus is common in small farms because of the low cost production. Residues of mushroom cultivation contain highly nutritive compounds resulted from metabolic activity of the fungus. In this work, the extract of spent pleurotus mushroom was used as an organic fertilizer to enhance Sakha 106 rice cultivar growth and productivity. The chemical analysis of spent extract (SE) verified that it contains considerable amount of reducing sugars, phenolic compounds and other macro and micro elements. Tow laboratory experiments were designed to study the effect of SE on soil micro biota and cyano bacterium Spirulina platensis. A field experiment continued for two successive seasons 2018 and 2019 was conducted where rice grains were soaked in SE then SE was applied by three methods, spraying on rice shoot system, soil drench and combined spraying plus soil drench. Results indicated that, SE improved soil microbial activity represented by total bacterial, fungal count and dehydrogenase activity in addition to soil respiration.Results of field trial indicated that the effect ofsoaking treatment was significant in spike length, number of full and empty seeds, grain and straw yield and nitrogen percent in grains,while the most effective treatment was the combination between spraying and soil amendment where the yield of grains and straw were clearly enhanced in addition to other yield characters.

“…These fungi promote the partial degradation of agricultural residues and favor the release of nutrients such as nitrogen, and also carbon and organic matter (Martins et al, 2018). The composite colonized by edible fungi to the soil can induce plant resistance to phytopathogens (Assi et al, 2007) or inhibit the action of pathogenic microorganisms (Ishihara et al, 2018), which can reduce the use of pesticides and an alternative to organic farming.…”

Production and mechanical evaluation of biodegradable composites by white rot fungi

et al. 2018

View full text Add to dashboard Cite

The production of plastic packing grows worldwide, resulting in the accumulation of these materials in the environment due to improper disposal and problems related to degradation. Alternatively, composites produced with agricultural residues and filamentous fungi may exhibit physical and mechanical properties similar to or greater than expanded polystyrene, depending on the fungal species and substrate of the cultivation. In the literature, no reports were found on the use of coconut powder and edible fungi of white rot in the mechanical properties of composites. Thus, the objective of this work was to select fungal isolates and to evaluate the period of cultivation in the mechanical resistance of composites produced in coconut powder supplemented with wheat bran. The experimental design was completely randomized in a 5 x 3 factorial scheme corresponding to the cultivation of five edible fungal isolates (Pleurotus ostreatus: POS-W, POS-SP1, POS-98/38; Pleurotus eryngii: POS ER and Pycnoporus sanguineus: PS) and three culture periods after complete colonization of the substrate (15, 30 and 45 days), with four replications. The period of cultivation of the fungal isolates may influence in the composite mass loss and volume loss. The compressive strength and tenacity of the composite are influenced by the fungal isolate and the time of cultivation. The isolates of Pycnoporus sanguineus, Pleurotus ostreatus and P. eryngii present potential characteristics for the production of biodegradable composites.
