Molecular modification of starch during thermomechanical treatment
Effect of different redox mediators during thermophilic azo dye reduction by anaerobic granular sludge and comparative s...
The impact of different redox mediators on colour removal of azo dye model compounds and textile wastewater by thermophilic anaerobic granular sludge (55 C) was investigated in batch assays. Additionally, a comparative study between mesophilic (30 C) and thermophilic (55 C) colour removal was performed with textile wastewater, either in the presenc...
Hulpmeststoffen in de biologische glastuinbouw : noodzaak en discussie
Door de hoge gewasbehoefte bij intensieve glasteelten in combinatie met de wettelijke beperkingen aan het gebruik van stalmest, is aanvullende bemesting met snelwerkende meststoffen noodzakelijk. In het kader van het BIOKAS-project is de werkzaamheid onderzocht van een groot aantal hulpmeststoffen, zowel van plantaardige als dierlijke oorsprong. De...
Advances in pectin and pectinase research : 2nd symposium on pectins and pectinases
The second international symposium on Pectins and Pectinases was organised by Wageningen University and Research Centre and was held in Rotterdam, May 6-10, 2001. This fruitful meeting was attended by around 130 participants from more than 20 countries, representing almost all of the groups/industries working worldwide on pectins and pectinases. Fo...

Grip op grillig afbraakproces
Korte uitleg over het belang van organische stof in de bodem, het proces van stikstofmineralisatie, en de afbraaksnelheid van organische stof, afhankelijk van grondsoort en soort organisch materiaal. Onderzoekers van WUR werken aan meer verfijnde computermodellen voor het berekenen van de stikstofmineralisatie
The potential of anaerobic bacteria to degrade chlorinated compounds
The Botrytis cinerea endopolygalacturonase gene family
C ell w all d egrading e nzyme s (CWDEs) secreted by microbial plant pathogens have been suggested to function as virulence factors. Evidence that particular bacterial CWDEs contribute to virulence has emerged in the last two decades. Targeted gene replacement of different genes encoding CWDEs resulted in mutants with reduced virulence on a number ...
Accessory enzymes from Aspergillus involved in xylan and pectin degradation
The xylanolytic and pectinolytic enzyme systems from Aspergillus have been the subject of study for many years. Although the main chain cleaving enzymes and their encoding genes have been studied in detail, little information is available about most of the accessory enzymes and their corresponding genes. This thesis describes the purification and c...
Degradation of chlorobenzoates and chlorophenols by methanogenic consortia
Pollution of the environment with chlorinated organic compounds mainly results from (agro)industrial activity. In many studies, biodegradation is examined under anaerobic conditions, because highly chlorinated compounds are more easily degradable under anaerobic than under aerobic conditions. Problems arise because these compounds can inhibit metha...
