Abstract Plant material obtained by pruning and production of deciduous fruit trees was evaluated as substrates for the production of the oyster mushroom, Pleurotus ostreatus . Lignified branches and stems from peach, apple, and pear trees were processed using a ripping machine to reduce the size of chips and to optimize disinfection. A completely randomized experimental design was proposed with six treatments (novel substrates) and one absolute control (100% hay substrate). Morphological variables such as thickness and diameter of the pileus, stipe length were assessed, as well as production variables (sprouting, fresh weight, and biological efficiency) and bromatological analysis (ash, ethereal extract, crude fiber, and crude protein). Apart from the 100%-hay substrate, biological efficiency ranged between 27% (100% apple tree as the substrate) and 140% (50% hay + 50% peach tree as the substrate). According to morphological analysis, the highest diameters were recorded from mixed substrates (50% hay + 50% wood), and a highly significant positive correlation was found between diameter and stipe length. Morphological parameters were not significantly correlated with biological efficiency. Analysis of biological efficiency confirmed that mixed substrates clustered together with 100%-wood substrates. Bromatological analysis showed that the mixed substrate (50% hay + 50% pear tree) had the highest protein content among the novel tested substrates. Bromatological parameters were not significantly correlated with biological efficiency. In conclusion, pruning residues from fruit trees can be valuable by using them as substrates for the cultivation of P. ostreatus . Production is quantitatively competitive with that using hay, on the condition that wood is mixed with hay.

Pleurotus ostreatus, an edible mushroom is an essential food product. Recognised as one of the cheapest sources of proteins, their high nutritional and anti-nutritional properties are of immense importance to humans. The present study evaluated the effect of sawdust and dried plantain leaves on the growth and yield of Pleurotus ostreatus. Sawdust and dried plantain leaves were composted into seven substrates; as single substrates and at different combinations. The composted substrates include sawdust 100 % (M0), Dry plantain leaves 100% (M1), Dry plantain leaves + sawdust at the ratio of 1:4 (M2), 2:3 (M3), 3:2 (M4), 1:1 (M5) and 4:1(M6). Growth parameters of interest assessed flush include mycelia running rate (MRR), area of pileus, length of the stipe, the girth of the stipe, fresh weight and dry weight, number of fruit body, total yield and biological efficiency. At the end of the three weeks spawn running period, M0 was overall best in supporting mycelia running rate with a mean MRR of 16.00 cm. M1 substrates produced mushroom with longer and bigger stipes (7.17 cm) at the first flush. A higher number of fruit bodies (82.66), total yield (130.35 g), and biological efficiency (43.45 g) were all seen in M0 substrates. Sawdust at 100 % (M0) proved to be the best substrate for the cultivation of Pleurotus ostreatus.

AbstractThe aim of this paper is to estimate which of disinfection method is more effective in case of higher yield and fewer cost in cultivation of Pleurotus ostreatus in rural areas.  For this purpose, four different treatments; scalping in hot water (60, 80 and 100°C), and chemical disinfection (1% formaldehyde) were compared with sterilization by autoclave. It has been noticed that method of disinfection affects mycelium growing duration(day), yield(g/kg), biological efficiency (BE%), avarage weight of fruitbody(g), diameter of pileus(cm), stipe lenght(cm) and width(cm).  P. ostreatus took significantly much time to colonise the substrate (19.9 days) disinfected by chemical disinfection compared with others. Chemical disinfection (271.28 g/kg and 91.96%) and scalding hot water at 80oC (263.42 g/kg and 90.83%) had highest productivity in terms of yield and BE, respectively, while scalding hot water at 60oC (136.08 g/kg and 46.92%) had least productivity. The largest diameter of fruitbody was obtained by scalding in hot water at 80oC, while the longest stipes were harvested in disinfected substrate by chemicals.  In conclusion, cheaper and more easily applecable scalping in hot water 80°C and chemical disinfection may be use for the disinfection of growing substrates instead of sterilization with autoclave in rural areas.Keywords: mushroom growing substrate, disinfection methods, autoclaved, scalding, chemical disinfection, Pleurotus ostreatus

Supplementation of mushroom substrates has been linked to a higher resistance against insect pests, although few studies show the impact of this supplementation on the different agronomical parameters of mushrooms or even their chemical composition. In this work, the variation in the biological and chemical composition of oyster mushroom (Pleurotus ostreatus var. florida (Jacq.) P. Kumm) was analysed after varying the substrate supplementation of calcium silicate (0, 0.5, 1, 2, and 4% (w/w%)) during two harvest flushes. Overall, supplementation did not change the weight, the number of fruiting bodies, biological efficiency, yield ratio, and productivity rate of the mushrooms, although the harvest flushes did show significant differences. Furthermore, slight changes were found in the chemical composition with an increase in vitamin D2 and tocopherols for the mushrooms with higher amounts of calcium silicate. Overall, the substrate supplementation did not seem to induce expressive changes or decrease production yields, and can, therefore, continue to be researched as a potential application to fight agronomical pests.

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.

Mushroom cultivation has continued to receive growing attention because of its nutritional and medicinal values. However, this study examined the effect of hardwood sawdust on the growth of Pleurotus ostreatus and Pleurotus pulmonarius were investigated. Relationship between fungal incidence of the substrates (sawdust) and that of the mushroom were examined. Both Pleurotus ostreatus and Pleurotus pulmonarius were inoculated on fermented and unfermented sawdust of Tectonal grandis and Celtis zenkeri. The fruiting bodies of the mushrooms were harvested and the growth parameters and biological efficiency was recorded. The isolated resident fungi were identified after obtaining pure cultures. The collected data were subjected to analysis (ANOVA) using Generalized Linear Model Procedure (GLM) of Statistical Analysis software (SAS). Means were separated using Duncan’s Multiple Range Test (DMRT) at p ≤ 0.05. Some of the growth parameters of P. ostreatus were significantly (p ≤ 0.05) better than that of P. pulmonarius. Tectona grandis and Celtis zenkeri sawdust had significant (p ≤ 0.05) impact on different growth parameters of the two mushrooms. Fermentation or non-fermentation of the substrates (sawdust) had no significant (p ≤ 0.05) impact on growth parameters of the mushrooms. Growth parameters of the two mushrooms were significantly better in 0% additive (p ≤ 0.05) than in the other additive concentrations. Five fungi were identified as indigenous fungi of the unfermented sawdust which did not significantly differ from those of the fermented sawdust and mushrooms. Nutritional composition of the mushrooms that grew on fermented and unfermented sawdust were good and comparable. The mushrooms were rich in protein, fibre, ash, moisture, fat and carbohydrate. Cultivation of mushrooms on hardwood sawdust is thus an effective means of managing such waste.

Summary An experiment has been conducted to study the effect of sludge concentration,  waste of paper industry using raw material of recycled paper, as media on oyster mushroom production and quality. Twelve treatment tested are combination of two oyster mushroom strains are oyster mushroom of Bogor (JTB) and oyster mushroom of Taiwan (JTT), three media composition (sawdust, sludge, and sawdust+ sludge (50/50, v/v), and two levels of supplement addition (with rice bran+gypsum+ lime and without) with 10 replications. The production of the  mushroom was conducted  in bag log capacity of 1 kg fresh weight (water content 50%). The result showed that sludge can be used as mixture of oyster mushroom production with the composition 50:50 v/v of sawdust and sludge. Since the higher number of contamination, addition of supplement reduce oyster mushroom production as well as biological efficiency, but increased protein content of fruiting body. The content of Cd, and Pb were below the permissible limits, Cu was higher than the limits but still in the range. The Fe content of mushroom fruit body was higher both in sawdust (147.92 – 149.56 ppm) and sawdust+sludge (295.82 – 335.12 ppm) as media. However, the uptake of Fe of JTT was less (49.08-59.64 ppm) compared to that of JTB (147.92-335.12 ppm).Ringkasan Penelitian dilakukan untuk mempelajari pengaruh konsentrasi sludge limbah pabrik kertas berbahan baku karton bekas sebagai medium terhadap produksi dan kualitas jamur tiram. Dua belas perlakuan yang diuji merupakan kombinasi dua galur jamur tiram, yaitu Jamur Tiram Bogor (JTB) dan Jamur Tiram Taiwan (JTT), tiga jenis komposisi medium (serbuk gergaji, sludge, dan sludge+ serbuk gergaji), dan dua tingkat suplemen (dengan dan tanpa) yang diulang 10 kali untuk masing-masing perlakuan. Produksi jamur tiram dilakukan menggunakan bag log  berkapasitas 1 kg basah (kadar air 50%). Hasil percobaan menunjukkan bahwa sludge dapat digunakan sebagai campuran serbuk gergaji dalam produksi jamur tiram dengan per-bandingan 50:50 (v/v). Pemberian suplemen menurunkan produksi jamur tiram demikian pula efisiensi biologi namun meningkatkan kadar protein tubuh buah. Di dalam tubuh buah JTB, kandungan logam Cd, dan Pb berada di bawah batas yang diijinkan, sedangkan kandungan Cu di atas ambang walaupun masih dalam kisaran. Kandungan  Fe dalam tubuh buah jamur relatif tinggi baik yang ditumbuhkan pada serbuk gergaji sebagai medium standar (147,92 - 149,56 ppm) maupun yang ditumbuhkan pada medium campuran sludge+serbuk gergaji (295,82 - 335,12 ppm). Serapan Fe tubuh buah JTT jauh lebih rendah (49,08- 59,64 ppm) dibandingkan dengan serapan Fe JTB (147,92-335,12 ppm).

The aim of this work was the use of Pleurotus ostreatus and Pleurotus sajor-caju for the previous lignocellulolytic decomposition of banana tree leaf straw and the further use of the degraded straw as substrate for the culture of Agaricus blazei. For optimising the production of A. blazei in terms of yield (Y%) and biological efficiency (BE%), adjustments to the composition of the substrate were evaluated in a 2(5) experimental design. The following components were tested in relation to % of substrate dry mass: urea (1 and 10%), rice bran (10 or 20%) or ammonium sulphate (0 or 10%), inoculum (10 or 20%) and the casing material (subsoil or burned rice husks). The best results (79.71 Y% and 6.73 BE%) were found when the substrate containing 10% of rice bran, without ammonium sulphate, inoculated with 20% and covered with subsoil was used.

This research was undertaken to evaluate the performance yield and biological efficiency of empty fruit bunch (EFB) and shredded palm pressed fibers (PPF) as an alternative substrate which is widely available for the cultivation of Pleurotus ostreatus. Currently rubber tree sawdust (RS) is used which is of limited supply. In this study, five different substrates were prepared either alone or in combinations in the ratio of 1:1 with rubber tree sawdust. These substrates were supplemented with fixed ratio of rice bran and limestone to increase the yield of Pleurotus ostreatus. Shredded palm pressed fiber (PPF) and rubber sawdust (RS) in the ratio of 1:1 took 52 days for the mycelium to fully colonize the substrate as compared to 49 days for rubber saw dust alone. The performance yield and biological efficiency observed for the substrates comprising of 50% PPF and 50% rubber tree sawdust and 50% EFB and 50% rubber tree sawdust(RS) are 2.325 kg with a biological efficiency of 232.5% and 1.380 kg with a biological efficiency of 138%, respectively. The results obtained show that both shredded palm pressed fiber (PPF) and empty fruit bunch (EFB) show great potential as substrate for the cultivation of Pleurotus ostreatus when incorporated with rubber tree sawdust (RS).
