Pleurotus ostreatus and a newly isolated Ganoderma lingzhi strain were evaluated for their laccase secretion capacity by solid-state fermentation with different agricultural and forestry residues. There was a significant difference among fungi for biosynthetic potential. In principle, the laccase secretion capacity of P. ostreatus CY 568 was stronger than that from G. lingzhi Han 500. Different species of fungi had a preference for agricultural and forestry residues. The presence of cottonseed hull and Populus beijingensis were helpful for accelerating the rate of laccase enzyme production of P. ostreatus CY 568. Cottonseed hull and corncob were useful for improving the production of laccase from G. lingzhi Han 500. Continuous and stable laccase production was found on cottonseed hull by P. ostreatus CY 568 and G. lingzhi Han 500. Maximum laccase activity obtained from P. ostreatus CY 568 on Toona sinensis, Sophora japonica, Salix babylonica, Populus beijingensis, corncob, cottonseed hull, and straw of Oryza sativa was higher than that from G. lingzhi Han 500, and was nearly 1.16-fold, 1.59-fold, 3.32-fold, 1.39-fold, 1.08-fold, 1.08-fold, and 1.36-fold, respectively. These findings will be helpful for developing new productive strains and expanding more species for industrial application to obtain efficient and low-cost laccase.

Laccase Production

Lakase merupakan salah satu enzim ligninolitik yang memiliki kemampuan mendegradasi lignin. Lakase telah diproduksi menggunakan jamur pelapuk putih Marasmius sp. dalam Fermentasi Kultur Padat (FKP) menggunakan jerami padi sebagai media pertumbuhan. Pengaruh sumber karbon yaitu glukosa, gliserol, dan molase dalam medium produksi lakase digunakan dalam penelitian ini. Konsentrasi 0,5%; 1,0%; dan 2,0% digunakan untuk tiap jenis sumber karbon. Hasil menunjukkan bahwa aktivitas tertinggi lakase diperoleh pada kultivasi hari ke 6-10  dengan masing-masing aktivitas (872,0 U/L (hari ke-6), 1516,67 U/L (hari ke-9) dan 1270,69 U/L (hari ke-10). Aktivitas lakase tertinggi diperoleh pada penggunaan medium gliserol dan molase masing-masing adalah 1422,36 U/L (pada konsentrasi 1%, hari ke-7) dan 113,19 U/L (pada konsentrasi 2%, hari ke-8). Aktivitas tertinggi tersebut sebanding dengan penggunaan medium glukosa. Oleh karena itu, gliserol dan molase dapat digunakan sebagai alternatif sumber karbon untuk produksi lakase dengan fermentasi kultur padat.Kata kunci: glukosa, gliserol, lakase, molase, Marasmius sp., fermentasi kultur padat Influence of Carbon Sources on Laccase Production by White Rot Fungus Marasmius sp. in Solid State FermentationAbstractLaccase is an one of the ligninolytic enzymes that capable to degrade lignin in biomass. Laccase has been produced by white rot fungus Marasmius sp. in Solid State Fermentation (SSF) using rice straw as the solid support media. The influence of carbon sources, i.e. glucose, glycerol and molasses in medium of laccase production were studied in this paper. The concentration of 0.5%, 1.0% and 2.0% were used for each carbon sources. The results showed that the highest lacase activity was obtained within 6-10 days of cultivation. Glucose concentration of 0.5%, 1.0% and 2.0% gave the highest laccase activity were 872.0 U/L (day 6), 1516.67 U/L (day 9) and 1270.69 U/L (day 10) respectively. The highest laccase activity on using glycerol and molasses was 1422.36 U/L (at concentration of 1 % on day 7th) and 1113.19 U/L (at concentration of 2% on day 8th), respectively. This activity was comparable to that of glucose substrate. Therefore, glycerol and molasses gave a potential chance as carbon sources for the strategy on low cost laccase production in solid state fermentation.Keywords: glucose, glycerol, laccase, molasses, Marasmius sp., solid state fermentation.

Laccase activity from Pleurotus ostreatus and Flammulina velutipes strains was investigated with various agro- and forestry residues by solid-state fermentation. Different species or strains belonging to the same species had the unique capacity of secreting laccase on solid-state fermentation with various agro- and forestry residues. Overall, the capacity of secreting laccase for P. ostreatus strains was superior to F. velutipes strains due to the value of maximum activity on various agro- and forestry residues, except on the stalk of straw. Compared with Populus beijingensis, corncob, and stalk of straw, the presence of cottonseed hull was helpful to improve laccase activity for P. ostreatus strains because the maximum laccase activity from cottonseed hull was higher than that from the other three agro- and forestry residues. The presence of stalk of straw was more helpful to improve laccase activity for F. velutipes strains because of the maximum laccase activity from stalk of straw was higher that from Populus beijingensis, corncob, and cottonseed hull. These results indicated the importance of selecting suitable agro- and forestry residues for fungi producing laccase. These findings contributed to the selection of suitable strains to obtain an integrated application of low-cost laccase in the factory.

White rot fungi of Marasmius sp. is a fungus which produce laccase in high activity. Laccase is one of the ligninolityc enzymes that capable to degrade lignin. This ability can be used for the pretreatment of lignocellulosic materials in the bioethanol production. Laccase was produced in flask by batch process using Solid State Fermentation (SSF). The optimisation was conducted by statistically of full factorial design. The particle size, moisture content, and Cu concentration were investigated in this study. Rice straw was used as solid substrate and the glycerol was used as the carbon sources in modified Kirk medium. The results showed that particle size of rice straw did not affect significantly to the enzyme activity. The highest laccase activity of 4.45 IU/g dry weight was obtained at the moisture content of 61% and Cu concentration of 0.1 mM.Keywords: laccase, Marasmius sp., optimisation, rice straw, solid state fermentation ABSTRAKJamur pelapuk putih, Marasmius sp. merupakan jamur yang menghasilkan enzim lakase dengan aktivitas tinggi.

Lignocellulosic Substrate

Lignocellulolytic white-rot fungi allow the bioconversion of agricultural wastes into value-added products that are used in a myriad of applications. The aim of this work was to use corn residues (Zea mays L.) to produce valuable products under solid-state fermentation (SSF) with Pleurotus ostreatus. White-rot fungus P. ostreatus was isolated from maize silage (MS) and thereafter it was inoculated on MS as substrate and compared with maize stover (MSt) and maize cobs (MC) to determine the best lignocellulosic substrate for the production of lignocellulolytic enzymes and extracellular protein. The MS gave the highest productivity of CMCase (368.2 U/mL), FPase (170.5 U/mL), laccase (11.4 U/mL), and MnPase (6.6 U/mL). This is compared to productivity on MSt of 222 U/mL, 50.2 U/mL, 4.55 U/mL, and 2.57 U/mL, respectively; and productivity on MC at the same incubation period as 150.5 U/mL, 48.2 U/mL, 3.58 U/mL, and 2.5 U/mL, respectively. The levels of enzyme production declined with increasing incubation period after 15 and 20 days using MS and MC, respectively, as substrates. Maximum liberated extracellular protein content (754 to 878 µg/mL) was recorded using MS, while a low amount (343 to 408 µg/mL) was liberated with using MSt and MC.
