Abiotic and biotic factors in the nutrient solution and filter skin (Schmutzdecke) of slow filters integrated to closed hydroponic greenhouse systems: Potential predictors for assessment of efficacy. Licentiate thesis. ISSN 1652-6880 , ISBN 91-576-7174-5. Rapid pathogen dispersal by circulating nutrient solutions in closed hydroponic systems poses a major threat to this produc...

Eicosatetraenoic acid (ETA, 20:4, ω-3) is the desaturation product of dihomo-gamma linolenic (DGLA, 20:3, ω-6) catalyzed by delta-17 desaturase, which considered as a healthy that helps to lower risk heart diseases. The oleaginous filamentous fungus, Mucor circinelloides, has been used for long time model micro-organism GLA production at industrial scales. However, M. circinelloides lacks key e...

In 2008 statewide surveys of symptomatic foliage of nursery plants from Tennessee resulted in isolation of 43 isolates of Phytophthora spp. This sample set includes four described species (P. citrophthora, P. citricola, P. nicotianae, P. syringae), and a provisional species of Phytophthora ('P. hydropathica'). At the same time a stream-baiting survey was initiated to recover Phytophthora from e...

In Poland, about 20% of forest nurseries use irrigation water coming from natural superficial reservoirs, presumed to be the first source of infection caused by harmful pathogens belonging to the Oomycota class, especially Phytophthora genus and Pythium genus. The forest nursery is the only place where forest managers can react before pathogens leave it with asymptomatic plants or soil attached...

BACKGROUND To isolate plant-derived compounds with antimicrobial activity from the leaves of Mikania micrantha, to determine the compounds configuration, and to evaluate their antimicrobial activity against eight plant pathogenic fungi (Exserohilum turcicum, Colletotrichum lagenarium, Pseudoperonispora cubensis, Botrytis cirerea, Rhizoctonia solani, Phytophthora parasitica, Fusarium solani, and...
