“…Being the major extractive constituents in Scots pine heartwood, resin acids probably accounted for the toxicity exerted by heartwood towards the fungal strains considered in his study. Resin acids were previously reported to cause severe inhibition of other wood-inhabiting fungi (Micales and Hans 1994;Eberhardt et al 1994).…”

SummaryThe fungal degradation of lipophilic extractives in sapwood and heartwood from Scots pine (Pinus sylvestris) was studied. In sapwood, the white rot fungi,Bjerkanderasp. andFunalia trogii, removed higher amounts of extractives than the sapstain strains,Ophiostoma ainoaeandCeratocystis allantospora. Triglycerides, long chain fatty acids, steryl esters and waxes in pine sapwood were almost completely degraded by all the fungi. Sterols and resin acids were also extensively degraded by the white rot strains; however, these components were not or only poorly removed by the sapstain fungi. The removal of total extractives by all the fungal strains was higher in sapwood as compared to heartwood. The highly concentrated extractive fraction in pine heartwood mainly consists of resin acids. As observed in sapwood, sapstain were also poorly effective in the degradation of the resin acids present in heartwood. The fungal degradation of heartwood extractives was not only limited by the degradative ability of the various test microorganisms, but also by the inhibitory effect exerted by the extractive fraction. The white rot fungusF. trogiiwas particularly inhibited on heartwood.Bjerkanderasp. showed a higher tolerance to toxic extractives and was the most efficient fungus in degrading extractive constituents in both Scots pine heartwood and sapwood. Therefore,Bjerkanderasp. strain BOS55 should be considered as a potential agent for pitch control in pulp and paper manufacture.

“…Substantial amount of cones are produced yearly throughout the world, especially in pine plantations grown for the pulp and paper industry. They are mainly composed of cellulose, lignin and resins that contain a variety of organic compounds 37,38 . Porous carbon from pine cone biomass have been extensively studied as biosorbent for metal, dye waste waters, nitrate uptake and removal of lead (II) ions from aqueous solutions by adsorption [39][40][41][42] …”

The environmental degradation and hazard to human life caused by the depletion of fossils fuels and the urgent need for sustainable energy sources to meet the rising demand in energy has led to the exploration of novel materials that are environmentally friendly, low cost and less hazardous to human life for energy storage application using the green chemistry approach.Herein, we report on the transformation of the readily abundant pine cone biomass into porous carbon via KOH activation and carbonization at 800 °C as electrode materials supercapacitor.The porous carbon material exhibited a mesoporous framework with a specific surface area of

Although in the course of the literature review porous carbon from pine biomass have been studied extensively as biosorbent for metal, dye waste waters, nitrate uptake and removal of lead (II) ions from aqueous solutions by adsorption [30][31][32], they have never been studied as electrode for electrochemical energy storage to the best of our knowledge.…”

Highlights• Sustainable carbon materials from pine cone biomass.• Hydrothermal treatment of the pine cone to produce hydrochar.• KOH activation and carbonization of the hydrochar to produce porous carbons.• Symmetric supercapacitor based on the porous carbon exhibit good electrochemical performance. Graphical abstract ABSTRACTLow-cost biomass-derived activated porous carbon from natural pine cones is synthesized using hydrothermal approach followed by KOH activation and carbonization. The produced carbon materials have a high surface area of 1515 m 2 g -1 with a well-developed 2 meso/micropores structure which is advantageous and favorable for mass transfer and ion accommodation for fast rate performance by providing pathways for electrolyte permeation and contact probability. Symmetric device fabricated using the obtained carbon material as electrode, exhibited good electrochemical performance with no degradation of capacitance after voltage holding at 1 V for about 60 h demonstrating good rate capability of the fabricated device. The results demonstrate the exciting potential of the pine cone derived carbons as a promising candidate for high-performance electrode materials for supercapacitors if fully explored.
