This study was focused on organic acids and metals in biofluids of wood. Without seasoning, fresh woods from spruce and bark, phloem, and heartwood from pine were used as materials, which were degraded with either microbes of oyster mushroom, baker's yeast, or lactic acid bacteria. Due to neutral pH
