In aquatic species of carnivorous utricularia, about 10 - 50 % of the total biomass consists of bladders. Utricularia bladders are physiologically very active organs though their chlorophyll content may greatly be reduced. To specify energetic costs of carnivory, respiration (RD) and net photosynthetic rate (PN) were compared in bladders and leaves or shoot segments of six aquatic utricularia s...

Endophytic fungi have been recognized as possible useful sources of bioactive metabolites. However, exopolysaccharide (EPS) production from endophytic fungi and its antitumor activity have been less explored. In the present study, endophtic fungus Bionectria ochroleuca M21 was exploited for the production of EPS in submerged culture. Among tested medium components, glucose, yeast extract, MgSO4...

Soil microbiological indicators are essential tools to understand how the management with cover crops interferes in activity and soil microbial community. Thus, objective of study was evaluate attributes performance bacterial community Brazilian Cerrado different crops. The experiment performed a randomized block design, evaluating seven crops, Sorghum bicolor, Crotalaria ochroleuca, Pennisetum...

The use of seaweed as a source bioactive extracts has received increased attention from the market in recent years—particularly for nutraceutical applications. In this context, study evaluated application biomass and three seaweeds Portugal: Ulva sp., Laminaria ochroleuca, Chondrus crispus. For each said seaweeds, four different were obtained using GRAS solvents—acetone (A), ethanol (E), ethano...

ABSTRACT The cultivation of cover plants is a strategy for improving the agricultural production environment and providing straw soil in no-tillage system, addition to cycling nutrients succeeding crops. This study aimed assess dry matter yield accumulation by grown alone or intercropped second crop after soybean their effects on cotton succession. treatments were: Urochloa ruziziensis; Pennise...
