In the search for alternatives to sawdust as growing media in commercial mushroom cultivation, three organic substrates obtainable as crop residue, maize husk, maize cob, and maize stalk, with each being supplemented with rice bran, were evaluated as growth media for the oyster mushroom,Pleurotus ostreatus(Kummer). For the tested alternatives to sawdust, the harvested weight of fruiting bodies that sprouted on a kilogram maize husk media per crop (32.99 g) was the highest. Sawdust media supported significantly (P<0.001) heavier fruiting bodies (42.18) than the maize residues. The peak mushroom harvests for the various substrates were obtained between the first and seventh fruiting body flushes. The biological efficiency of the substrates, which measured usable nutrients indicated that maize stalk supplemented with rice bran, was 39% compared to that of the sawdust media (60%). The maize husk media and the maize cob media had biological efficiencies of 32% and 9.5%, respectively. These results indicate that two of the tested growing media (maize stalk or husk) produced mushrooms with yield characteristics that were comparable to the well-used sawdust in the cultivation of oyster mushrooms. The environmental and economic parameters involved in the use and carting of sawdust make these on-farm crop residues a viable alternative for mushroom cultivation in especially nonforest zones of Ghana.

The results of studies conducted during the harvest of fruiting bodies of oyster mushrooms indicate that the development of harmful micromycetes during the first wave of fruiting was less than in the second about twice. It is established that the distribution of microorganisms is also influenced by the placement of substrate blocks in the fructification premises. In the first wave of fruiting, the number of affected blocks varied depending on the tier location. The least affected blocks were found on the 3rd tier, which is the highest – 3,6 %. The yield loss on this tier was 3.1 kg of mushrooms. On the second tier, the percentage of the contaminated blocks was 10,4. The largest amount of infected substrate was observed on the 1st tier – 27,1 %. The increase in the affected blocks on the 1st and 2nd tiers is due to excessive moisture, which leads to the flow of drops from the upper bags to the lower ones. Observation during the second wave of fructification has shown, that the dissemination and development of the diseases was considerably bigger. In the 1st tier, the substrate blocks were infected with the micromycetes by 34,6 %, and the rate of disease development was 13,4 %. The smallest amount of infected substrate was found on the 3rd tier – 4,4 %, and the rate of micromycetes was 1,8 %. Substrate blocks having infection with 4-5 point development were removed and disposed. The average lesion score ranged from 2 to 3. During the first and second waves of fruiting, the frequency of micromycetes on substrate blocks increases due to the development of Trichoderma (up to 69,4 %), Penicillium (up to 15,7 %), and Aspergillus spp. (up to 8,3 %), commonly known as green mold substrate pathogens.

AbstractExtracts of the fruiting bodies of the Oyster mushroom (Pleurotus ostreatus) grown on wood substrates (beech, oak, linden, walnut, poplar) and extracts of the fruiting bodies of the Oyster mushroom (Pleurotus pulmonarius) grown in nature on aspen wood were used to determine the total phenols, total flavonoids, lycopene and β-carotene. The content of individual antioxidants varies considerably depending, not only on the substrate, but also on the extracting agents. The highest content of total phenols and total flavonoids was found in methanol and water extracts of the fruiting bodies of the Oyster mushrooms grown on oak and linden substrates. The maximum content of lycopene and β-carotene was determined in acetone and n-hexane (ratio 4 : 6) extracts of the fruiting bodies of the Oyster mushroom grown on an oak block. The results obtained in this study demonstrated that the quantitative and also probably the qualitative composition of the antioxidants in the fruiting bodies of Oyster mushrooms depended considerably on the substrate composition.

Summary Sludge is a solid waste abundantly available on paper factory that is economically unutilized and tends to pollute environment. This waste can be used as growth media for oyster mushroom (Pleurotus ostreatus) as edible mushroom and ligninolytic enzymes production as well. A research has been conducted to study the activity pattern of ligninolytic enzymes of oyster mushroom grown on the sludge waste of recycle paper factory. Six treatments were examinated consisted of three media combinations (sawdust, sludge, sludge mixed with sawdust), with and without supplementing with rice bran, lime, and gypsum, and two mushroom strains Bogor oyster mushroom (JTB) and China Taipei oyster mushroom (JTT). Monitoring of ligninolytic enzyme activity consisting of laccase, mangan peroxidase (Mn-P) and lignin peroxidase (Li-P),  was subsequently regularly started since inoculation, at vegetative phase (four and six weeks), primordial formation, phase of fruiting body formation, and two weeks after formation of fruiting body. Each treatment was repeated three times, so that 216 bag logs of oyster mushroom cultures were performed. The results showed that laccase, Mn-P, and Li-P activities could be observed on sludge or mixture of sludge+sawdust media inoculated with P. ostreatus. Generally, the highest activity of ligninolytic enzymes especially for laccase and MnP were observed at the first vegetative growth phase i.e. before emerging primordial of fruiting body (1.697 & 2.113 U/mL, 4.394 & 2.314 U/mL  respectively for JTB and JTT laccase and JTB & JTT Mn-P). The highest Li-P activity was affected by the kind of media and strain of inoculum. In sludge medium, the highest Li-P activity was observed in  vegetative growth phase (2.706 & 4.014 U/mL respectively for JTB and JTT) while in a mixture of sludge + sawdust the highest activity of that enzyme was observed in primordial phase of growth (2.509 & 1.9 U/mL respectively for JTB and JTT). Addition of supplement to the sludge increased ligninolytic activity, while laccase activity of sludge was suggested could be more enhanced by mixing the sludge with sawdust and enrich with rice bran, gypsum and lime. Ringkasan                                                Sludge merupakan limbah padat yang tersedia melimpah di pabrik kertas dan belum dimanfaatkan secara ekonomis sehingga berpotensi mencemari lingkungan. Limbah ini dapat dimanfaatkan sebagai medium tumbuh jamur konsumsi seperti jamur tiram (Pleurotus ostreatus) dan penghasil enzim ligninolitik. Penelitian dilakukan untuk mempelajari pola aktivitas enzim ligninolitik jamur tiram pada limbah sludge pabrik kertas selama fase vegetatif sampai setelah fase generatif. Enam perlakuan yang diuji berupa tiga kombinasi komposisi medium (serbuk gergaji, sludge, campuran sludge dan serbuk gergaji), dengan dan tanpa pengayaan, yaitu penambahan dedak, kapur, dan gipsum,  serta dua strain jamur tiram Bogor (JTB) dan jamur tiram China Taipei (JTT). Pengamatan aktivitas enzim ligninolitik meliputi lakase, mangan peroksidase (Mn-P) dan lignin peroksidase  (Li-P) dilakukan sejak saat inokulasi, pada fase vegetatif (empat dan enam minggu), pada saat pembentukan primordia, fase tubuh buah, dan dua minggu setelah pembentukan tubuh buah. Masing-masing perlakuan diulang tiga kali sehingga terdapat 216 bag log jamur tiram. Hasil penelitian menunjukkan bahwa aktivitas ligninolitik dijumpai pada medium sludge dan campuran sludge+serbuk gergaji yang diino-kulasi P. ostreatus. Aktivitas enzim ligninolitik tertinggi khususnya lakase dan MnP teramati pada fase pertumbuhan vegetatif pertama yaitu sebelum terbentuknya primordia (1,697 & 2,113 U/mL, 4,394 & 2,314 U/mL  masing-masing untuk lakase JTB dan JTT dan MnP  JTB & JTT). Aktivitas LiP tertinggi dipengaruhi oleh jenis medium dan strain inokulum. Pada medium sludge, aktivitas LiP tertinggi dijumpai pada fase vegetatif (2,706 & 4,014 U/ml masing-masing untuk JTB dan JTT) sedangkan pada medium campuran sludge+serbuk gergaji, aktivitas enzim  ter-tinggi dijumpai  pada fase primordia (2,509 & 1,9 U/ml berturut-turut untuk JTB dan JTT). Pengayaan sludge meningkatkan aktivitas ligninolitik, sedangkan aktivitas lakase pada sludge diduga dapat lebih ditingkatkan dengan menambahkan serbuk gergaji disertai pengayaan berupa gipsum, dedak, dan kapur.

An experiment was conducted at Mushroom Lab of Horticulture Centre under Department of Agricultural Extension (DAE), Khairtala, Jessore to determine the performance of different substrates on the yield of oyster mushroom (Pleurotus ostreatus). Sugarcane bagasse, sawdust, and coconut coir individually and their combinations were used as substrates. The experiment was laid out in Completely Randomized Design (CRD) with five replications. Data were taken from 1st and 2nd flush of different growth and yield attributes of mushroom. The maximum number of effective fruiting bodies was obtained from sawdust (40) and the lowest number (31.6) from combination of sawdust and coconut coir (1:1). In the 1st flush, the maximum weight of individual fruiting body was observed in coconut coir and minimum in sawdust. The highest biological (186.06 g) and economic yield (180.64 g) were obtained from coconut coir and the lowest from sugarcane bagasse. The maximum and minimum harvest index was found in 1st flush at coconut coir and combination of sawdust and sugarcane bagasse (1:1), respectively. Most yield attributes were found higher in coconut coir. Economic yield was positively correlated to number of effective fruiting bodies, pileus diameter, and biological yield.
