Environmental and nutritional factors affecting geosmin synthesis by Anabaena sp.
TLDR
It was concluded that at 20 degrees C, increasing light intensity favors less chla synthesis and higher geosmin synthesis; at 17 microE/m2/s, increasing temperature stimulates chla production while repressing geosmine synthesis (above 20 degreesC).
Comparing denitrification rates and carbon sources in commercial scale upflow denitrification biological filters in aquaculture
Abstract Aerobic biological filtration systems employing nitrifying bacteria to remediate excess ammonia and nitrite concentrations are common components of recirculating aquaculture systems (RAS).
Effects of carbon source, phosphorus concentration, and several micronutrients on biomass and geosmin production by Streptomyces halstedii
TLDR
Of the seven micronutrients tested, zinc, iron, and copper had the most profound effects on biomass and geosmin production.
The effect of pomegranate (Punica granatum L.) byproducts and ellagitannins on the growth of human gut bacteria.
TLDR
The results showed that pomegranate byproducts and punicalagins inhibited the growth of pathogenic clostridia and Staphyloccocus aureus, while relatively small growth inhibition by ellagic acid likely resulted from decreasing media quality due to the formation of tannin-protein complexes.
Phytotoxic and fungitoxic activities of the essential oil of kenaf (Hibiscus cannabinus L.) leaves and its composition.
TLDR
The chemical composition of the essential oil of kenaf (Hibiscus cannabinus) was examined by GC-MS and had antifungal activity against Colletotrichum fragariae, ColletOTrichum gloeosporioides, and Collettrichum accutatum but exhibited little or no algicidal activity.
Invited Paper: Chemicals from nature for weed management
TLDR
Natural products represent a vast repository of materials and compounds with evolved biological activity, including phytotoxicity, some of which can be used directly or as templates for herbicides.
Comparative physiology of geosmin production by Streptomyces halstedii and anabaena sp.
TLDR
Comparing effects of selected environmental factors on biomass and geosmin production by the actinomycete Streptomyces halstedii and the cyanobacterium Anabaena sp.
Impact of depuration of earthy-musty off-flavors on fillet quality of Atlantic salmon, Salmo salar, cultured in a recirculating aquaculture system
TLDR
The main fillet quality concerns for producers of RAS-cultured salmon are flavor, texture and lipid levels during the pre-harvest purging process, and fillet color quality was not compromised during the depuration periods used in these studies.
Geosmin causes off‐flavour in arctic charr in recirculating aquaculture systems
The ‘earthy' and ‘muddy' off-flavours in pond-reared fish are due to the presence of geosmin or 2-methylisoborneol in the flesh of the fish. Similar off-flavours have been reported in fish raised in
The case against direct incentives and the search for alternative approaches to better land management in Central America
Land shortages are forcing smallholder farmers to cultivate steeplands. Resulting accelerated soil erosion is being addressed by the promotion of soil and water conservation (SWC) technologies, such
