Potential of endophytic fungus Phomopsis liquidambari for transformation and degradation of recalcitrant pollutant sinapic acid

Phomopsis liquidambari colonization promotes continuous cropping peanut growth by improving the rhizosphere microenvironment, nutrient uptake and disease incidence

“…The endophytic fungus Ceratobasidium stevensii increased invertase activity but not urease in the rhizosphere soil, while we observed that both urease and invertase activities were significantly increased by P. liquidambari inoculation, and the increase was more noticeable and durable than that of C. stevensii , implying that the addition of P. liquidambari significantly improved the rhizosphere soil activity and fertility. Phomopsis liquidambari inoculation also significantly reduced the accumulation of phenolic acids in the peanut rhizosphere, probably due to the synergetic degradative action of P. liquidambari with native microbes, as already demonstrated . In addition, the higher polyphenol oxidase activity in the inoculated soils should also be considered a notable factor, showing that the application of beneficial endophytic fungi efficiently degraded soil autotoxins, which might be conducive to increasing peanut nodulation and N 2 fixation .…”

“…Phomopsis liquidambari inoculation also significantly reduced the accumulation of phenolic acids in the peanut rhizosphere, probably due to the synergetic degradative action of P. liquidambari with native microbes, as already demonstrated. 20,27,30,31 In addition, the higher polyphenol oxidase activity in the inoculated soils should also be considered a notable factor, 9 showing that the application of beneficial endophytic fungi efficiently degraded soil autotoxins, which might be conducive to increasing peanut nodulation and N 2 fixation. 46 Therefore, the endophytic fungus P. liquidambari may be considered a potential microbial agent to improve rhizosphere soil enzyme activity and alleviate allelopathic stress in the field when applying the continuous cropping system to peanuts.…”

“…Previous pot experiments found that inoculation with P. liquidambari increased the yield of peanuts . Further studies indicated that P. liquidambari could degrade phenolic allelochemicals and improve the soil microbial activity and community composition in the simulated contaminated soils . A recent study found that the endophytic fungus P. liquidambari can colonize peanut roots and increase nodulation and N 2 fixation in a plant growth chamber .…”

“…28 Further studies indicated that P. liquidambari could degrade phenolic allelochemicals and improve the soil microbial activity and community composition in the simulated contaminated soils. 20,24,26,27,[29][30][31] A recent study found that the endophytic fungus P. liquidambari can colonize peanut roots and increase nodulation and N 2 fixation in a plant growth chamber. 32 However, whether P. liquidambari could effectively colonize the peanut rhizosphere and roots in continuous cropping fields, and the effects of its colonization on peanut rhizosphere microenvironment, nutrient uptake and disease control, are still unclear.…”

A Two-Step Bioconversion Process for Canolol Production from Rapeseed Meal Combining an Aspergillus niger Feruloyl Esterase and the Fungus Neolentinus lepideus

“…In N. lepideus BRFM15 culture broth from FA to VG, were also detected as traces by GC–MS: vanillic acid, vanillin, vanillyl alcohol, syringic acid, syringaldehyde, syringyl alcohol, protocatechuic acid and derivatives of p -methoxycinnamate. In the light of the present work and reports on fungal aromatic metabolisms in the literature [ 46 , 47 , 48 ], it seemed that, for N. lepideus , the route of SA and FA biotransformation into the corresponding vinyl derivatives was highly favored compared to the others pathways. Especially, the bioconversion of hydroxycinnamic acids into the benzoic acid derivatives, via a β -oxidation-like reaction, is a minor pathway in N. lepideus BRFM15 unlike other Polyporaceae known for their aromatic flavor metabolism, including P. cinnabarinus [ 46 ] and Trametes suaveolens [ 47 ].…”
