“…As mentioned earlier, good mycelium growth comprises often with good fruiting bodies production. In previous investigations made by (Stoknes et al, 2013;Jasińska et al, 2016a and2016b) mushroom production on compost using digestate from AD biogas production was successful. A. subrufescens yielded on the average flush 187 g kg −1 in that study on digestate composts which encourages reusing the digestate not only in agriculture field production but also for mushroom production.…”

Digestate is remaining material after anaerobic digestion (AD) of a biodegradable feedstock. The AD process produces two main products: digestate and biogas; digestate is considered as a waste; however, it found application in agriculture i.e. as a soil conditioner or cultivation substrate component. Digestate is rich in nitrogen and phosphorus and can be used as a substrate component for mycelial growth of mushrooms. Aim of the study was examination of agar media supplementation with digestate from AD of foodwaste material on mycelial growth of cultivated and medicinal mushrooms. Mycelial growth of four mushroom species was investigated: Coprinus comatus, Ganoderma lucidum, Agaricus subrufescens and Laetiporus sulphureus. First experiment investigated four mushroom species and 3 digestate-only based agar media with growing amount of digestate extract. Later fastest growing mushrooms from exp. 1, C. comatus and G. lucidum, was chosen, mycelial growth was performed on 2 digestate-only based agar media and 2 what/digestate extract based agar media. Wheat-based and manure-based agar media was used as control medium. Study confirmed positive effect of digestate from AD as an addition or main component of agar media culture for mushroom mycelium growth. The amount of digestate extract affected mycelial growth of investigated species. The best agar media was digestate-based only with 25 g of extract and wheat/digestate based (150/50 g extract). The fastest and the best growth were obtained for C. comatus. The residue from AD biogas production could have found additional application as media product for mushroom mycelia production and further as a component for mushroom cultivation substrate.

“…Digestate from AD was successfully used in previous studies on Agaricus bisporus and Agaricus subrufescens by Stoknes et al (2013; and Jasińska et al (2016a and2016b). Availability of the cultivation substrate components is one of the most important factors deciding on their commercial utilization.…”

Agaricus bisporus is in general cultivated on wheat and rice straw in China. However, millet straw is a potential alternative resource for Agaricus bisporus cultivation, but this has hardly been studied. In the present study, the feasibility of millet straw based mushroom production was analyzed by three successive trials. Mature compost demonstrated high quality with total nitrogen, pH, and C/N ratio of 2.0%, 7.5, and 18:1 respectively, which was suitable for mushroom mycelia growth. During composting, 47–50% of cellulose, 63–65% of hemicellulose, and 8–17% lignin were degraded, while 22–27% of cellulose, 14–16% of hemicellulose, and 15–21% of lignin were consumed by A. bisporus mycelia during cultivation. The highest FPUase and CMCase were observed during mushroom flushes. Endo-xylanase had the key role in hemicellulose degradation with high enzyme activity during cultivation stages. Laccase participated in lignin degradation with the highest enzyme activity in Pinning stage followed by a sharp decline at the first flush. Yield was up to 20 kg/m2, as this is similar to growth on wheat straw, this shows that millet straw is an effective resource for mushroom cultivation. Actinobacteria, Bacteroidetes, Chloroflexi, Deinococcus-Thermus, Firmicutes, and Proteobacteria were the dominant phyla, based on 16S rRNA gene sequencing during composting. The key environmental factors dominating bacterial communities of the samples were determined to be pH value, cellulose content, and hemicellulose content for prewetting and premixed phase of basic mixture (P0); moisture content for phase I (PI); and nitrogen content, lignin content, and ash content for phase II (PII), respectively.

“…In the combined experiment, fresh mushroom compost ("Phase III", not previously used for mushroom production) was used instead of SMC. Mushroom compost preparation and cultivation procedures followed Stoknes et al [21]. Green waste compost (GC) was produced from a mix of municipal park and household garden waste in a commercial composting yard, where the waste was ground up, and then composted for up to one year in turned windrows until full maturity.…”

When using food and green waste composts as peat-free plant growing media, there is a challenge that nutrient immobilisation and high pH and salts content limit plant growth. The present study explored the use of spent mushroom compost (SMC) of Agaricus subrufescens in a sustainable plant growing system where only vermicompost from digested food waste and composted green wastes were used, even for the seedling stage. However, negative effects of high compost inclusion were offset by adding SMC. Significantly higher plant yield was obtained in several of the SMC amended treatments in four out of five lettuce experiments and in one tomato experiment. In addition, an experiment with cucumbers showed that nutrients were not available to the plant when the mushroom mycelium was actively growing, but became available if the mushroom mycelium had been inactivated first by pasteurisation. A significant effect from SMC was not observed under full fertigation. This study demonstrated that the addition of pasteurised Agaricus mycelium colonised compost can successfully offset negative effects from high pH and EC as well as limited nutrient supply (and nitrogen immobilisation) in peat-free, compost-based growing media.

Anaerobically digested food waste in compost for Agaricus bisporus and Agaricus subrufescens and its effect on mushroom productivity

Abstract: Digestate successfully substituted chicken manure in straw composts without affecting mushroom yields for both species. There were no clear differences between straw digestate and control composts in terms of mushroom dry matter, size, nitrogen or ash content.
