Dynamics of the chemical composition and productivity of composts for the cultivation of Agaricus bisporus strains

Abstract

Two compost formulations based on oat straw (Avena sativa) and brachiaria (Brachiaria sp.) were tested for the cultivation of three Agaricus bisporus strains (ABI-07/06, ABI-05/03, and PB-1). The experimental design was a 2 × 3 factorial scheme (composts × strains) with 6 treatments and 8 repetitions (boxes containing 12 kg of compost). The chemical characterization of the compost (humidity, organic matter, carbon, nitrogen, pH, raw protein, ethereal extract, fibers, ash, cellulose, hemicellulose, and lignin) before and after the cultivation of A. bisporus and the production (basidiomata mass, productivity, and biological efficiency) were evaluated. Data were submitted to variance analysis, and averages were compared by means of the Tukey’s test. According to the results obtained, the chemical and production characteristics showed that the best performances for the cultivation of A. bisporus were presented by the compost based on oat and the strain ABI-07/06.

Lignocellulose utilization and bacterial communities of millet straw based mushroom (Agaricus bisporus) production

“…BE of our study was 68.40%, 70.42%, and 72.58%, respectively. BE of T1 was the lowest since the physico-chemical properties of compost at the end of PII were out of suggested ranges with 23% of C/N ratio and 1.76% of nitrogen content 17,24,29 . In previous study of wheat straw and chicken manure based compost, mushroom yield and BE were 18.90 kg/m 2 and 88.7.9%, respectively 26 .…”

“…At the end of PII, the physico-chemical properties of compost were the key factors to determine the mushroom yield, which need to be within specific ranges to obtain maximum mushroom yield 33 . The moisture, total nitrogen, pH, and C/N ratio should be in the range of 68–72%, 2.0–2.4%, 7.4–7.6, and 17–20:1, respectively 17,24,29 . After composting, total nitrogen, pH, and C/N ratio of T2 and T3 samples were about 2.1–2.2%, 7.4–7.7, and 18:1–19:1, respectively, suggesting that the two compost samples based on millet straw were of high quality and suitable for mushroom growth.…”

“…The pH was analyzed in a 1:10 (w/v) fresh substrate water extract using a pH meter. Moisture content was assayed using fresh samples by the dry weighing method 17 . Frozen fresh samples were freeze dried and milled (<1 mm) for determination of other contents 3,16 .…”

“…Plant cell walls are mainly composed of cellulose, hemicellulose and lignin 13,14 . Fate of lignocellulose derived components and their degrading enzymes during composting and mushroom cultivation were reported for wheat straw based compost 1,15–17 .…”

Cultivation of Agaricus bisporus (button mushroom) and its usages in the biosynthesis of nanoparticles

“…(Andrade et al 2013), reed plant (Phragmites australis) straw (Muslat et al 2011), water hyacinth (Eichhornia crassipes) (Reddy et al 2013) and others. Wheat straw with waste tea leaves (Gulser et al 2003;Peker et al 2007) and waste paper (Sassine et al 2005;Sassine et al 2007) were used in the casing layer.…”
