Agricultural Straws

Agricultural straws (AS) may serve as potential base-substances in the production of Agaricus bisporus. Six AS that occur across China were investigated in a two-stage composting experiment; lignocellulose components, AS morphology, and the effects of different AS on mushroom yields from 2015–2017 were examined. In addition, microbial biodiversity and their impact on substrate degradation were studied using 16S gene sequenc based on six different AS on the 3rd (I.F), 6th (I.S), and 10th (I.T) day of Phase I, and Phase II (II). Results showed that the six different AS exhibited differences in the progression of degradation under the same compost condition; the wheat straw, rice straw, and cotton straw induced a significantly higher mushroom yield than did the others (P < 0.05); Thermobispora, Thermopolyspora, and Vulgatibacter genera may play an important role in the different AS degradations. According to our experiments, we can adjust formulations and compost methods to obtain high-yield mushroom compost based on different AS in the future.

Mushroom Yield

Supplementation of compost at casing with various ground seeds caused greater increases in mushroom yield than their respective seed oil meals when supplemented and compared at equivalent rates of nitrogen addition.Supplementation with various refined and crude seed oils increased mushroom yield, particularly in the first break or flush of mushrooms. This constitutes evidence for a relationship between lipid metabolism and the initiation of fruiting in the cultivated mushroom, Agaricus bisporus (Lange) Sing.

Mushroom Yield

The toxicity of boron (B) and copper (Cu) to cultivated mushrooms was tested in 2 experiments. The growth of mushroom mycelium (Agaricus bisporus) on potato dextrose agar in vitro was inhibited by additions of B as H3BO3 and Cu as CuSO4.5H20. Boron was more inhibitory than Cu to mycelial growth. Addition of B to compost at spawning decreased sporophore (i.e. mushroom) production and increased B concentrations in the sporophore. Boron added at 35 mg/kg of fresh compost gave a 10% yield reduction and this was associated with a sphorophore tissue B concentration of 170 mg/kg dry weight. Addition of Cu to the compost had no effect on the final yield of mushrooms but increased Cu concentrations in the sporophores. Boron added at 5, 10 and 20 mg/kg and Cu at 10 mg/kg of fresh compost stimulated sporophore growth at first flush but this was not evident in total mushroom yield from all flushes. There was a significant negative linear effect of mushroom tissue B (r2=0.98) and Cu (r2=0.54) at harvest 1 (day 1) on the change in tissue B or Cu from harvest 1 to 6 (day 17). This suggested that tissue B was buffered around 7 mg/kg and Cu around 73 mg/kg. The results indicate that the levels of B and Cu which are normally contributed to mushroom compost from poultry litter are unlikely to cause significant losses in mushroom production.

This study was carried out during 2012-2014 to determine the effect of locally available casing materials with association of bio-inoculant Pseudomonas putida. Six different combinations of casing mixtures were amended for evaluating its effect on yield, biological efficiency, protein and carbohydrate contents of Agaricus bisporus. A mixture of FYM + GLS + Vermi-compost + P. putida gave higher mushroom yield, biological efficiency, protein and carbohydrate content. It gave better yield (1306 g), biological efficiency (28.7%), protein (34.07%) and carbohydrate content (5.07%) respectively when compared with other treatments. In addition, waste tea leaves took minimum period (33.00 days) for initiation of pin head when compared with others. Locally available casing materials along with P. putida incorporated in the casing soil can be an important factor to obtain maximum and assured yield in mushroom cultivation.

Background: Certain microorganisms during the preparation of substrate for growing Agaricus bisporus are of great interest for the conversion of organic material and for the excretion of a wide range of metabolites with growth regulation activities that may affect the mycelial growth processes and mushroom yield. Adding beneficial microorganisms in the substrate may be a biotechnological alternative to optimize A. bisporus cultivation. Objective: Isolate and evaluate thermophilic microorganisms from self-heating pasteurized substrate with growth-promoting effects on A. bisporus cultivation. Methods: Different microorganisms were isolated and selected at 45 and 55 °C. They were tested for siderophore production, 1-octen-3-ol consumption, and phosphate solubilization in coculture with A. bisporus to determine their growth effects on potato dextrose agar (PDA) and on sterile pangola grass (Digitaria eriantha). Results: Of the 106 microorganisms isolated, 88 % were able to grow in the presence of 1-octen-3-ol, while 1 % had the capacity to produce siderophores, and 55 % had the ability to solubilize phosphate. The strains Bacillus hisashii ECS-B-65, B. licheniformis ECS-B-78, Rhizomucor pusillus ECS-710 and ECS-712, Aspergillus fumigatus ECS-709, and Thermomyces sp. ECS-711 were found to have a positive effect on A. bisporus mycelial growth.

Agaricus subrufescens, known as Sun Mushroom, is a high-value mushroom because of its medicinal properties, used as nutraceutical food to stimulate the immune system and to prevent some diseases, including cancer. Mushrooms are generally characterized by their great ability to bioaccumulate heavy metals and other toxic substances from the mushroom compost. Sugarcane bagasse is a common raw material used in mushroom compost production for Agaricus subrufescenscultivation, whereas insecticides, such as fipronil, can be applied to combat several pests in sugarcane crops. For this reason, we aimed to assess mushroom yield and fipronil bioaccumulation in Sun Mushroom, regarding different concentrations added to the mushroom compost (0, 8, 16 and 32 mg kg-1) and casing layer (0, 2, 4 and 8 mg kg-1). Each experiment was arranged in a completely randomized design with four replicates. Regression analysis from mushroom production data was applied using SISVAR 5.1 program. Fipronil was quantified using gas-liquid chromatography (HP 6890) with thermionic detector (NPD). Mushroom yield was affected when fipronil was added, decreasing from 12% (compost with 0 mg kg-1 of fipronil) to 4.8% (compost with 32 mg kg-1). However, bioaccumulation was not detected. In contrast, insecticide bioaccumulation was detected when adding fipronil to casing layer, increasing from <0.01 mg kg-1 (casing layer with 2 mg kg-1) to 0.26 mg kg-1 (casing layer with 8 mg kg-1), however, mushroom yield was not affected.
