Influence of the co-fungal treatment with two white rot fungi on the lignocellulosic degradation and thermogravimetry of corn stover

Biological de-lignification of straw by white-rot fungi seems a promising way of improving its nutritive value. The bio-conversion of lignocellulosic materials is circumscribed to the group of white-rot fungi, of which some species of Pleurotus are capable of producing upgraded spent-straws as ruminant feed (Fazaeli et al., 2004). Treating of cereal straw with white-rot fungi as animal feed was studied by several workers (Gupta et al., 1993; Zadrazil, 1997). However, most of the trials were conducted at in vitro stage and used cell wall degradation and in vitro digestibility as an index to evaluate the biological treatments. This experiment was conducted to study the effect of fungal treatment on the voluntary intake, in vivo digestibility and nutritive value index of wheat straw obtained from short-term and long-term solid state fermentation (SSF).

Dry Matter Digestibility

Abstract Agricultural by-products such as corn stover (CS) are abundantly available in many countries; however, its high content of neutral detergent fiber (NDF) and lignin (L) and low protein content, causes low digestibility and nutrient availability for ruminants. The production of edible fungi could improve the digestibility of the CS because fungi can break down the cross-links between cell wall components. The aim of the study was to evaluate the effect of the invaded CS-based substrate used in the production of 21 white rot fungi of the species: Auricularia sp (Auri), Ganoderma sp (Gano), Hericium sp (Heri), Lentinula edodes (LC, L5, L9, L15, L21), Pleurotus eryngii (Pe-PQ, Pe-MB), Pleurotus djamour (Pd-Pro, Pd-UTMR) and Pleurotus ostreatus (Po-IAP, Po-Psma, Po-P14, Po-POS, Po-IE202, Po-JP, Po-P35, Po-P38, Po-Sfco) on crude protein (CP), NDF and L content and in vitro dry matter digestibility (IVDMD). The variables were analyzed in a completely randomized design with the MIXED procedure of SAS and the comparison of the means was made with the Tukey analysis. For CP, a significant increase (P < 0.05) was observed from 10% (Pe-MB) to 41% (LC) in comparison with the substrate without inoculation (C). There was a decrease (P < 0.05) of NDF from 2% (LC) to 10% (Pd-PRO) against C. Fungal treated CS had no effect on L (P < 0.05) as compared to C. Treatments increased (P < 0.05) IVDMD from 3% (L15) up to 36% (Po-POS) for all fungal strains, except for Pe-PQ and Po-Sfco in comparison with C. There was a positive correlation (r2=0.21, P < 0.05) between CP and IVDMD. An equation was obtained to predict IVDMD [IVDMD=0.40578 + 358.38(%ADF)–358.02(%NDF)+358.17(%HEM)–0.3211(%DM), R2=0.32 (P < 0.05)]. In conclusion the mycelial invasion of white rot fungi on a CS-based substrate, increased CP content, decreased NDF and improved IVDMD, making it a viable option to increase the digestibility of CS.

Dry Matter Digestibility

Abstract Corn stover (CS) is an agricultural byproduct available in many countries for animal feed. However, due to its high lignin (L) and neutral detergent fiber (NDF) content it has a low digestibility. The production of edible fungi, using CS-based substrate, is an option to improve CS digestibility, as fungi can break down the cross-links between cell wall components. The aim of the study was to evaluate the effect of fungal treated CS from 17 species of white rot fungi: Lentinula edodes (L5, L9, LC,L15), Hericium sp (Heri) and Pleurotus djamour (Pd-Pro, Pd-UTMR) Pleurotus eryngii (Pe-PQ, Pe-MB), Pleurotus ostreatus (Po-IE202, Po-IAP, Po-Psma, Po-P14, Po-POS, Po-JP, Po-P38, Po-Sfco) on crude protein (CP), L and NDF content and in vitro dry matter digestibility (IVDMD). The composition of the substrate (C) was CS (80.55%), ground sorghum (5.98%) wheat bran (3.89%), corn gluten (4.89%), CaCO3 (3.89%) and CaSO4 (0.89%). The variables were analyzed as a completely randomized design using the MIXED procedure of SAS. Means were compared with the Tukey procedure. A significant increase (P < 0.05) of CP from 10% (Po-P38) to 69% (LC) was observed, except for Pd-UTMR, Po-IAP, Po-Psma, Po-P38 and Po-Sfco that showed similar content to the C. There was a decrease (P < 0.05) in the NDF from 10% (Heri) to 34% (L15) in relation to the C. The L content did not decrease in comparison with the C (P < 0.05). Furthermore, 13 treatments significantly increased (P < 0.05) IVDMD from 24% (Po-P14) to 42% (Pd-UTMR), except for Po-P38, Po-JP, LC and Heri in comparison with the C. In conclusion, the cultivation of white rot fungi, such as Pd-UTMR, Po-IAP, Po-Psma, LC, L9 and L15 using CS as substrate, improved CP content and increased IVDMD of CS, suggesting that which can be a good alternative for feeding ruminants.

Fungal treatment has been recently considered as a promising method for improving the nutritive value of straw (Zadrazil et al., 1997). Several studies have been conducted to identify species of white-rot fungi for assessing their ability to improve the nutritive value of straw (Yamakamwa et al., 1992). Since there are many species of fungi in nature, there is an interest in characterising of some species. The objectives of this experiment were to study the effect of five Pleurotus fungi on the chemical composition, in vitro digestibility and in sacco degradability of wheat straw and evaluate their effect in upgrading the nutritive value of lignicellulosic materials.

Effluent from the local batik home industry is a serious problem, because the effluent discharge generated is spread in different places. Untreated effluent can cause environmental pollution, such as in groundwater reservoirs,because most is discharged into rivers. The aim of this research was to evaluate the bioremediation potential of indigenous fungi in liquid culture media with Indigosol Blue 04B (IB) batik effluent. The fungi isolates tested were Aspergillus sp. 1, Aspergillus sp. 2 and Aspergillus sp. 3, isolated from dye effluent soil and batik effluent, and compared to white rot fungi (Phanerochaete chrysosporium) as a positive control. The physiochemical properties of IB batik effluent before and after fungal treatment were investigated. All of these parameters before the fungal treatment were above the recommended standard values based on the Governor regulation of Yogyakarta Special Region No. 7/2010. The level of biochemical oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS), total suspended solids (TSS), and electrical conductance (EC) was reduce by Aspergillus spp. The highest percentage reduction was achieved by Aspergillus sp. 3, namely 88.34% BOD, 89.11% COD, 75.77% TSS, 85.85% TDS and 71.21% EC, after 3 days of incubation. These results show that the positive control isolate had the lowest value. The study confirms the ability of indigenous fungi isolates in the remediation of IB batik effluent and their potential for future analysis in the treatment of all types of batik effluent.

This objective is to elucidate the effect of purple field corn stover treated with Pleurotus ostreatus and Volvarialla volvacea on feed utilization, ruminal ecology, and CH4 synthesis in tropical beef cattle. Four male Thai native beef cattle (100 ± 30 kg of body weight (BW) were assigned randomly as a 2 × 2 factorial arrangement in a 4 × 4 Latin square design. Factor A (roughage sources) was rice straw and purple field corn stover and factor B was species of white-rot fungi (P. ostreatus and V. volvacea). After fermentation, crude protein (CP) was increased in rice straw and purple field corn stover fermented with P. ostreatus and V. volvacea. The unfermented purple field corn stover contained 11.8% dry matter (DM) of monomeric anthocyanin (MAC), whereas the MAC concentration decreased when purple field corn stover was fermented with white rot fungi. There were no changes (p > 0.05) in DM intake of body weight (BW) kg/d and g/kg BW0.75 among the four treatments. The organic matter (OM), CP, and acid detergent fiber (ADF) intake were different between rice straw and purple field corn stover and were the greatest in the purple field corn stover group. Moreover, the current study showed that neutral detergent fiber (NDF) and ADF digestion was higher in purple field corn stover than in rice straw, but there were no significant differences between P. ostreatus and V. volvacea. There were significant effects of roughage sources on ammonia nitrogen (NH3-N) at 4 h after feeding. Bacterial population was changed by feeding with purple field corn stover fermented with P. ostreatus and V. volvacea. On the other hand, the number of protozoa was reduced by approximately 33% at 4 h after feeding with purple field corn stover (p < 0.01). Propionic acid concentration was different between roughage sources (p < 0.01) enhanced with purple field corn stover fermented with P. ostreatus and V. volvacea. In addition, methane production decreased by 15% with purple field corn stover fermented with P. ostreatus and V. volvacea compared to rice straw. There were significant differences on all nitrogen balances parameters (p < 0.05), except the fecal N excretion (p > 0.05) were not changed. Furthermore, microbial crude protein and efficiency of microbial N synthesis were enhanced when purple field corn stover fermented with P. ostreatus and V. volvacea was fed compared to rice straw group. Base on this study, it could be summarized that P. ostreatus or V. volvacea can enhance the quality of purple field corn stover and modulate rumen fermentation and feed digestion in Thai native beef cattle.
