AbstractAgricultural waste disposal is one of the main concerns in today's world that can cause environmental pollution. Utilisation of agro-waste materials to grow mushrooms is an eco-friendly method to reduce pollution. Therefore, various agricultural waste materials, such as wheat straw, rice straw and cotton waste, were utilised for the production of milky mushroom. Among the substrates used in this study wheat straw showed superior substrate for the production of milky mushroom. The agronomic traits studied such as total yield, number of fruiting bodies, the maximum diameter of pileus and stalk length, biological efficiency, protein contents, phosphorous and potassium contents were observed on wheat straw substrate. Peat moss, loam soil and spent mushroom substrate were used as casing materials. Among the casing materials used, the highest yield and biological efficiency were observed on peat moss. The results also indicated that the addition of supplements with the substrate improved yield and yield contributing characteristics. Among the tested supplements (wheat bran and rice bran), wheat bran was the best supplement for wheat straw substrate to cultivate milky white mushroom.

A study was conducted to evaluate the effect of different spawn rates and substrate supplementation on yield of Pleurotus pulmonarius (Fr.) Quel. Among six spawn rates viz., 0.5%, 1%, 2%, 4%, 6% and 8%, respectively tried on wheat straw substrate, the spawn run was fastest (10.50 days) when spawn dose was 8%, followed by 6%, 4%, 2%, 1% and 0.5%, respectively. The pinheads appeared in 12.27 days by using spawn @ 8%, which proved to be the best spawn dose followed by 6%, 4%, 2%, 1% and 0.5%, respectively. Highest yield of 168.7 per 200g dry substrate was achieved @ 8% spawn rate. Lesser yields were recorded when spawn rate was reduced. The results also reveals the significantly highest biological efficiency of 84.33% at 8% spawn rate followed by 6%, 4%, 2%, 1% and 0.5%, respectively. It was concluded that spawn run was rapid at higher spawn rate but there was not much difference in yield when spawn dose was increased from 4 to 8%. Considering spawn cost and performance shown by different doses, 2-4% was found optimum dose for its cultivation.In case of substrate supplementation, wheat straw supplemented with cotton seed meal supported maximum mycelial growth (10.50 days of inoculation) and took mini-mum time for pinheads initiation (13.67 days). Similarly, maximum yield (155.3g) with biological efficiency of 77.65% was recorded on wheat straw supplemented with cotton seed meal followed by supplementation of saw dust, wheat straw (control), calcium ammonium nitrate (CAN), ammonium nitrateand urea, respectively. These studies will help to mushroom growers for selecting the most suitable spawn rate and also opens viable option of supplementation as wheat straw + cotton seed meal for better growth behaviour and optimum yield potential of Pleurotus pulmonarius as well as other oyster mushrooms cultivation.

AbstractThe “replacing wood by grass” project can partially resolve the conflict between mushroom production and balancing the ecosystem, while promoting agricultural economic sustainability. Pleurotus pulmonarius is an economically important edible and medicinal mushroom, which is traditionally produced using a substrate consisting of sawdust and cottonseed hulls, supplemented with wheat bran. A simplex lattice design was applied to systemically optimize the cultivation of P. pulmonarius using agro-residues as the main substrate to replace sawdust and cottonseed hulls. The effects of differing amounts of wheat straw, corn straw, and soybean straw on the variables of yield, mycelial growth rate, stipe length, pileus length, pileus width, and time to harvest were demonstrated. Results indicated that a mix of wheat straw, corn straw, and soybean straw may have significantly positive effects on each of these variables. The high yield comprehensive formula was then optimized to include 40.4% wheat straw, 20.3% corn straw, 18.3% soybean straw, combined with 20.0% wheat bran, and 1.0% light CaCO3 (C/N = 42.50). The biological efficiency was 15.2% greater than that of the control. Most encouraging was the indication that the high yield comprehensive formula may shorten the time to reach the reproductive stage by 6 days, compared with the control. Based on the results of this study, agro-residues may be used as a suitable substitution for sawdust and cottonseed hulls as the main cultivation substrates of P. pulmonarius. These results provide a theoretical basis for the “replacing wood by grass” project on edible mushroom cultivation.

The present experiment was conducted in order to prepare a suitable substrate composition using wheat straw and also to ascertain the effect of various levels of nitrogen supplementation on the yield and biological efficiency of Pleurotus mushroom. The strain DMRP-205 of Pleurotus djamor was used in the study. Among different treatment combinations, maximum biological efficiency of 75.11% was recorded in T2 with 0.5% of urea supplementation. It was also observed that, though the higher nitrogen supplementation does not increase the yield proportionately, it has significant effect on the spawn run period, cropping duration and colour intensity of the basidiocarp. The study necessitates the nitrogen supplementation at optimum levels (0.5%) to realize the maximum yield in P. djamor cultivation. Bangladesh J. Bot. 50(2): 227-233, 2021 (June)

Two-phase olive mill waste (TPOMW, “alperujo”) is a highly biotoxic sludge-like effluent of the olive-oil milling process with a huge seasonal production. One of the treatment approaches that has so far received little attention is the use of TPOMW as substrate for the cultivation of edible mushrooms. Fifteen fungal strains belonging to five species (Basidiomycota), that is,Agrocybe cylindracea,Pleurotus cystidiosus,P. eryngii,P. ostreatus, andP. pulmonarius, were evaluated for their efficacy to colonize media composed of TPOMW, which was used either raw or composted in mixtures with wheat straw in various ratios. Qualified strains exhibited high values of biological efficiency (e.g., 120–135% forPleurotusspp. and 125% forA. cylindracea) and productivity in subsequent cultivation experiments on substrates supplemented with 20–40% composted TPOMW or 20% raw TPOMW. Only when supplementation exceeded 60% for raw TPOMW, a negative impact was noted on mushroom yields which could be attributed to the effluent's toxicity (otherwise alleviated in the respective composted TPOMW medium). Earliness and mushroom size as well as quality parameters such as total phenolic content and antioxidant activity did not demonstrate significant differences versus the control wheat-straw substrate. The substrates hemicellulose content was negatively correlated with mycelium growth rates and yields and positively with earliness; in addition, cellulose: lignin ratio presented a positive correlation with mycelium growth and mushroom weight forA. cylindraceaand with earliness for all species examined. TPOMW-based media revealed a great potential for the substitution of traditional cultivation substrates by valorizing environmentally hazardous agricultural waste.

In this study, some local available organic matters, which are including wheat straw (Triticum aestivum), sawdust, and fiber of date palm (Phoenix dactylifera L.), were used for growing and cultivating of bright yellow oyster mushroom Pleurotus cornucopiae var. citrinopileatus. The possibility of using date palm fiber (in mixtures with other organic residues) as a substrate for the cultivation and production of fruiting bodies of P. cornucopiae var. citrinopileatus was investigated. This mushroom is capable of biorecycling and utilization of some mixtures of lignocellulosic substrates successfully, especially the mixture S3 (50% wheat straw, 30% sawdust, and 20% date palm fiber). The lower mycelia completion time was 17 days, that shown in bags of the S3 substrate. Date-palm fiber substrate exhibited best growth intensity level (moderate) significantly (p<0.05). The total yield and biological efficiency percent recorded approx. 90 g and 23% on the S3 substrate respectively, as a higher percent significantly (p<0.05), while sawdust substrate alone was an unsuitable medium for cultivation and production of this mushroom. Finally, the use of date-palm fibers in mixtures is usefulness in producing a fresh edible and medicinal mushroom.INTERNATIONAL JOURNAL OF ENVIRONMENTVolume-5, Issue-4, Sep-Nov 2016, page: 56-65

The purpose of this study was to investigate the suitability of different spent mushroom sawdust wastes (SMSWs) and different proportions of SMSWs as potential substrates for the cultivation of Auricularia polytricha by evaluating yield and biological efficiency of the fruiting body. Nine SMSWs were respectively utilized as the main ingredient in the cultivation of A. polytricha. Then, spent Pleurotus eryngii, Pleurotus cystidiosus, and Pleurotus ostreatus sawdust wastes were screened among these nine SMSWs to be utilized as substrate and to determine the suitable proportion of SMSW in the cultivation of A. polytricha based on their yields and biological efficiencies. The highest yield and biological efficiency (total of two flushes) of A. polytricha cultivation on a single SMSW substrate was obtained with spent P. eryngii sawdust waste, followed by spent P. cystidiosus and P. ostreatus sawdust wastes. These three SMSWs were then applied in nine combination substrates, which were screened based on yield and biological efficiency for cultivation of A. polytricha. The combination substrate with the highest yield and biological efficiency of A. polytricha cultivation was P. eryngii (PES) + P. cystidiosus spent sawdust (PCYS) (235.4 g/bag yield and 58.85% biological efficiency); its yield was 1.62 folds higher than that of the control. From the results, we found that it was feasible to use spent sawdust wastes of P. eryngii and P. cystidiosus to replace sawdust for cultivation of A. polytricha.
