Beneficiation of eucalyptus tree barks in the context of an integrated biorefinery – Optimisation of accelerated solvent extraction (ASE) of polyphenolic compounds using response surface methodology

Author: Andrew, Jerome E ; Masetlwa, J ; Tesfaye, T ; Sithole, Bishop B Date: Dec 2020 Bark from trees obtained from sustainably managed plantations used in the production of timber, pulp and paper is an under-utilised waste in many countries across the world. However, in the context of an integrated biorefinery, they may serve ... Read more
Cellulose fibril aggregation studies of Eucalyptus dissolving pulps using atomic force microscopy

Author: Chunilall, Viren ; Wesley-Smith, J ; Bush, T Date: Nov 2006 Dissolving pulp is the end-product of acid-bisulphite pulping and bleaching processes, during which almost all non-cellulosic wood components are removed to produce dissolving pulp with final a cellulose purity of up to 96%. Dissolving pulp ... Read more
Cellulose fibril aggregation studies of eucalyptus dissolving pulps using atomic force microscopy

Author: Chunilall, Viren ; Wesley-Smith, J ; Bush, T Date: Nov 2006 The work presented will report on the use of AFM to study the CFA characteristics of dissolving pulp of a clone of Eucalyptus grown in compartments with contrasting growth rates (low and high), at different stages of the pulping process (solid ...

Clonal variability for water use efficiency and carbon isotope discrimination ( 13C) in selected clones of a few Eucalyptus species

Author: Mohan Raju, B ; Kumar, V ; Narasimhamurthy, TN ; Sheshshaayee, MS ; Verryn, SD ; Naidoo, N ; Bindumadhava, H ; Mohan, V ; Prasanna, KT ; Prasad, TG ; Udayakumar, M Date: Nov 2011 Eucalyptus, one of the fast growing tree species extracts water from a depth of up to 15 meters. As a prolific producer of biomass/ wood, eucalyptus has been included as commercially important tree species under various afforestation programmes ... Read more
The effects of chemical and structural factors on the enzymatic saccharification of Eucalyptus sp. samples pre-treated by various technologies

Author: Thoresen, M ; Malgas, S ; Gandla, ML ; Jonsson, LJ ; Sithole, Bishop B ; Pletschke, BI Date: Aug 2021 Lignocellulosic biomass is an important renewable resource to produce biofuels, due to its abundance and high polysaccharide content. Bioconversion is generally achieved in two stages: (i) pre-treatment, to reduce biomass recalcitrance, and ... Read more
The effects of wood storage on the chemical composition and indigenous microflora of eucalyptus species used in the pulping industry

Author: Ramnath, L ; Sithole, Bishop B ; Govinden, R Date: Feb 2018 Lipophilic extractives naturally occurring in wood tend to coalesce during pulping to form pitch deposits, which have particularly undesirable effects on the pulping process and quality of pulp produced. A chemical characterization of different ... Read more
The floral transcriptome of Eucalyptus grandis

Author: Vining, KJ ; Romanel, E ; Jones, RC ; Alves-Ferreira, M ; Hefer, CA ; Amarasinghe, V ; Dharmawardhana, P ; Naithani, S ; Ranik, M ; Wesley-Smith, J ; Solomon, L ; Jaiswal, P ; Myburg, AA ; Strauss, ST Date: Oct 2015 As a step toward functional annotation of genes required for floral initiation and development within the Eucalyptus genome, we used short read sequencing to analyze transcriptomes of floral buds from early and late developmental stages, and ...

Gums, badgers, and economics

Author: Van Wilgen, BW Date: 2007 Gums trees (in the genus Eucalyptus, from Australia) are not set to ‘disappear’ (even if some people wanted them to). Gums form an important component of the forest industry and, at last count, they covered over 540 000 ha in formal plantations ... Read more
Longer-term effects of pine and eucalypt plantations on streamflow

Author: Scott, DF ; Prinsloo, FW Date: Oct 2008 The longer-term effects of afforestation with Pinus radiata and Eucalyptus grandis on streamflows were analyzed using data from two paired-catchment experiments in South Africa. The experiments are rare in that they have been maintained over ... Read more
Native forest generation in pine and eucalypt plantation in Northern Province, South Africa

Author: Geldenhuys, CJ Date: Dec 1997 Commercial plantations in South Africa have been established mainly in grasslands adjacent to native forest which occur as small, scattered patches, restricted to valleys and scarps by regular fire-prone grasslands. Under storey vegetation ... Read more
Response in water yield to the thinning of Pinus radiata, Pinus patula and Eucalyptus grandis plantations

Author: Lesch, W ; Scott, DF Date: 15 Dec 1997 The paired catchment method was used to test for the effects of thinning on the water yield in three afforested catchments in South Africa, namely, Biesievlei, Jonkershoek, 98% afforested with Pinus radiata (three thinnings); Westfalia catchment ...

Standardization and optimization of core sampling procedure for carbon isotope analysis in eucalyptus and variation in carbon isotope ratios across species and growth conditions

Author: Raju, M ; Naidoo, N ; Sheshshaayee, MS ; Verryn, SD ; Kamalkannan, R ; Bindumadhava, H ; Varghese, M ; Snedden, C ; Prasad, TG ; Udayakumar, M Date: Nov 2011 13C is a well established surrogate for water use efficiency (WUE). However, variation due to aspect, length of branch and position In canopy can cause potential errors. Hence, experiments were conducted to standardize the sampling procedures ... Read more
A technique to identify annual growth rings in Eucalyptus grandis using annual measurements of diameter at breast height and gamma ray densitometry

Author: Naidoo, Sasha ; Ahmed, F ; Pammenter, N ; Zbonak, A Date: Jun 2010 A technique was developed to identify annual growth rings in E. grandis using a combination of annual measurements of diameter at breast height (DBH) from permanent sample plot (PSP) datasets and bark-pith density profiles. By assessing the ... Read more
Verification of 3-PG growth and water-use predictions in twelve Eucalyptus plantation stands in Zululand, South Africa

Author: Dye, PJ ; Jacobs, S Date: 17 May 2004 The South African forestry industry perceives Process-based forestry models as important tools for improving predictions of growth and water use in forest plantations. The 3-PG process-based forest model was evaluated in South Africa using ... Read more
