Apart from the unique case of Leonardo da Vinci, the scientific and the artistic eye cast on living things have rarely resided i...
the influence of initial moisture content on wood decay at different levels of atmospheric oxygen concentration was studied. three fungi, coriolus versicolor (c. versicolor) a white rot, coniophora puteana (c. puteana) a brown rot, and chaetomium globosum (c. globosum) a soft rot, were chosen. the mycelia of the fungi were inoculated in to mini blocks of fagus sylvatica (beech) and pinus sy...
