“…In the present study, P . ostreatus treated rice straw recorded the least A:P ratio (2.63) which is similar to the observation (3.27) made by Zuo et al 42 only that his value was comparatively higher. Just as in the present study, P .…”

The study sought to investigate the potentials of axenic cultures of Pleurotus ostreatus, Phanerochaete chrysosporium and their coculture (P. chrysosporium and P. ostreatus) to break down lignin and to enhance the rumen fermentability of rice straw. Rice straw was fermented by two lignin-degrading fungi, namely, P. ostreatus, P. chrysosporium and its coculture (P. ostreatus and P. chrysosporium) with uninoculated straw as control under solid-state fermentation employing a completely randomized research design. The coculture exhibited a mutual intermingling plus inhibition interaction. The fungi treatment increased the crude protein from (5.1%) in the control to (6.5%, 6.6%, and 6.7%) in the P. ostreatus, P. chrysosporium and coculture respectively. The coculture treated straw had a lower lignin content (5.3%) compared to the P. chrysosporium (6.2%) with the P. ostreatus recording the least (3.3%) lignin fraction. Treatment of rice straw with coculture improved the in vitro dry matter digestibility (68.1%), total volatile fatty acids (35.3 mM), and total gas (57.4 ml/200 mg) compared to P. chrysosporium (45.1%, 32.2 mM, 44.4 ml/200 mg) but was second to P. ostreatus (75.3%, 38.3 mM, 65.6 ml/200 mg). Instead of an anticipated synergistic effect from the coculture, a competitive antagonistic effect was rather observed at the end of the study, a condition that can be attributed to the coculture behavior.

“…In the rumen, a rise in feed e ciency is linked with a lower A:P ratio as acetate within animal tissue is non gluconeogenic and copious amount is oxidized or utilized for lipogenesis 31 . In the present study, P. ostreatus treated rice straw achieved a deceased A:P ratio (2.63), which contradicted the high value (3.27) reported in the study of Zuo, et al 32 . This variation could originate from the different substrate, incubation period and temperature utilized.…”

The objective of this study was to investigate the axenic culture of Pleurotus ostreatus, Phanerochaete chrysosporium, and the coculture (P. chrysosporium and P. ostreatus) for their potential to break down lignin and to enhance the rumen fermentability of rice straw. Rice straw was fermented by two lignin-degrading fungi, namely, P. ostreatus, P. chrysosporium, and coculture (P. ostreatus and P. chrysosporium) under solid-state fermentation (SSF). The coculture exhibited a mutual intermingling plus inhibition interaction. Coculture treated straw had a lower lignin content (5.26%) compared to P. chrysosporium axenic treated straw (6.18%), although P. ostreatus axenic treated straw was the lowest (3.27%). The polysaccharide content of coculture treated straw was higher than P. chrysosporium axenic treated straw, although smaller than P. ostreatus. P. ostreatus and coculture suitably delignified rice straw without adversely affecting cellulose. Treatment of rice straw with coculture improved in vitro dry matter digestibility (68.08%), total volatile fatty acids (35.27%), and total gas (57.4 ml/200 mg) compared to P. chrysosporium (45.09%, 32.24%, 44.39 ml/200 mg) but was second to P. ostreatus (75.34%, 38.31%, 65.60 ml/200 mg). The coculture via synergistic interaction has the potential to decompose lignin and improve the nutritive value of rice straw than P. chrysosporium.

“…Air dried samples (220 mg) were incubated in 30 mL buffered rumen fluid for 72 h at 39°C. The IVGP of all the samples was manually recorded at 0, 2, 4, 6,8,10,12,16,20,24,30,36,42,48,60, and 72 h of incubation, and related to the organic matter (OM) content. The data shown here represent average values between the triplicates.…”

“…Therefore, our hypothesis is that employing the acidophilic white rot fungal treatment of the ensilage corn stover could improve its in vitro rumen degradability without high cost sterilization. Irpex lacteus (I. lacteus), a kind of medicinal fungus, allows for efficient enzymatic conversion of the plant material and can forcefully degrade the acid detergent lignin (ADL) [11,12]. In the present study, I. lacteus was employed to treatment of corn stover silages inoculated with LAB to further increase its nutritional potential.…”

Objective: This study investigated a method of preparing corn stover for Irpex lacteus (I. lacteus) treatment to improve its in vitro rumen degradability under non-sterile conditions.Methods: Corn stover was inoculated with Lactobacillus plantarum (L. plantarum), Lactobacillus buchneri (L. buchneri), and an equal mixture of these strains, and ensiled for 0, 3, 7, 14, and 28 days. After each period, a portion of the silage was sampled to assess the silage quality, and another portion of the silage was further treated with I. lacteus at 28°C for 28 d. All the samples were analyzed for fermentation quality, chemical composition, and in vitro gas production (IVGP) as a measure of rumen fermentation capacity.Results: Lactic acid bacteria (LAB) was found to improve the silage quality of the corn stover, and the corn stover silage inoculated with L. plantarum produced more lactic acid and higher IVGP than other silage groups. The I. lacteus colonies flourished in the early stage of corn stover silage, especially on the 3-d corn stover silage inoculated with both L. plantarum and L. buchneri. This led to an 18% decrease in the acid detergent lignin content, and a 49.6% increase in IVGP compared with the raw stover.Conclusion: The combination of ensiling with the mixed LAB inoculation and I. lacteus treatment provided a cost-effective method for the improvement of the IVGP of corn stover from 164.8 mL/g organic matter (OM) to 246.6 mL/g OM.
