Distinguishing isolates of Aureobasidium on the basis of their ability to utilise lignin breakdown products as a sole carbon source
1996 - IRG/WP 96-10151
Wild isolates of Aureobasidium were obtained by dilution plating from a ca 20 year old painted pine window frame. Four isolates were obtained from the paint/wood interface region and four isolated from regions deep in the wood. The isolates were then used to inoculate liquid cultures containing ferulic acid, a lignin breakdown product, present as the sole carbon source. Ability of the isolates to use ferulate, judged by fungal yield, viable propagule count and absorbance at 280 nm (a measure of the aromatic's final concentration) was dependent on the site of isolation. Isolates from the paint/wood interface were consistently better at utilising ferulate than those isolated from deep in the wood and a possible reason for this is suggested.

Färbeverfahren zur Unterscheidung von Holzzonen mit unterschiedlichem Absorptionsvermögen, insbesondere bei Fichtenholz (Picea abies Karst.). [Staining method for distinguishing zones of wood with different absorption behaviour, particularly in spruce (Picea abies Karst.)]
1980 - IRG/WP 3163
A simple regressive staining method for crosscut wood surfaces is described. Phloroglucinol-hydrochloric acid serves as stain; flowing water and a solution of sodium carbonate are used for development and fixation of a picture showing the differences of absorption. Hydrophobic zones and, contrary to this, zones with a high water content can also be shown. Comparing green spruce wood before and during drying, the formation of a "secondary heart" became visible. The staining method is useful for solving practical questions and for tests with spruce. It is applicable to other wood species if these show similar differences in absorption.

Chapter 3 - Identification of bamboo
2007 - IRG/WP 07-10635-03
To ensure the exact identification of bamboo species of Bangladesh possibly easy and non-instrumental distinguishing characters have been described for prompt and easy assimilation by all level of people usually involved in the system of bamboo protection practices or in the modern bamboo management system. The important bamboo species of Bangladesh have been described with their external morphology and their distinguishing characters along with their colored photographs. These bamboos are also available in South and South East Asia; hence their identification will be helpfui to the people who are really dealing with bamboos in their daily life.
