The white rot fungus Bjerkandera sp. strain BOS55 extensively delignified and bleached oxygen-delignified eucalyptus kraft pulp handsheets. Biologically mediated brightness gains of up to 14 ISO (International Standards Organization units) were obtained, providing high final brightness values of up to 80% ISO. In nitrogen-limited cultures (2.2 mM N), manganese (Mn) greatly improved manganese-de...

Background Wood is the most important natural and renewable source of infinite energy, but this is not their only function, it also has great significance to the buildings and other products [1]. Eucalyptus, the genus that includes more than 500 species, is among the key forest species planted around the world to solid wood, and mainly for the pulp and paper industries. Aiming at the sustainabl...

Eucalyptus globulus is an important rapid-growing trees in Eucalypts that applied for agroforestry and tree improvement programs. It has been used as a source of pulp in paper industry, essential oil and honey production. Asexual propagation with conventional methods such as cutting and graft wasnot possible or obtained success was very low, because of hard proliferation of adventitious roots. ...

This study aims to understand the effect of micro- and nanofibrillated cellulose (MNFC) on tensile index, softness, water absorbency tissue paper. MNFC was produced from four different fiber sources. The results show that acts as an effective strength enhancer at expense a reduced softness. impact source manufacturing cost trade-off with performance also investigated. MNFCs southern bleached ha...

Abstract Several eucalyptus pulps (85% of cellulose) with different lignin and HexA content (unbleached, TCF ECF) as well cotton linters (97% were treated ozone (at pH doses) in order to modify its fibre-components. Special interest was given the introduction functional groups carbohydrates. The presence these mainly identified by chain scissions due carbonyl (CS C=O ) produced cellulose during...

Various viewpoints were proposed to explain the causes of recent years’ severe drought occurred in Yunnan and Guizhou, China. In general there are two parties of viewpoints, the Eucalyptus cause and climate change cause. I think Yunnan-Guizhou drought has been mainly caused by abnormal climate change. Eucalyptus was not significant in the formation of Yunnan-Guizhou drought. However, the forest...
