Highlights Defoliation initiates physiological recovery and chemical defense mechanisms in Phalaris aquatica . Under infrequent defoliation treatment, P. has high DM production. severity on herbage regrowth was associated with variation of secondary metabolite content antioxidant activity. may be suited to conservation pasture systems; the interval between cuts is about six weeks maximize rates...

conclusions the crude extract of streptomyces sp. acs52 had high antibacterial activity against a wide spectrum of bacteria and could be of interest due to its features such as ability to grow at low temperatures and alkaline ph levels. results streptomyces sp. acs52 is a cold-resistant alkalophilic bacterium strain with antibacterial activity against a broad spectrum of pathogenic bacteria. th...

blastocystis hominis is a protozoan parasite which mainly found in human fecal samples both from symptomatic patients and asymptomatic population in developing countries. in this study we reported a patient referred to gi clinic with abdominal pain, nausea, vomiting, fever for 2 or 3 days and passed watery stools because of blastocystis sp. subtype 2 infection.

Field experiments were conducted to study weed population shifts in long-term conservation tillage systems. The objectives of this study were to determine weed community abundance, diversity and composition on conventional tillage (CT), minimum tillage (MT), no-tillage with paraplow (ZT) and no-tillage (NT) systems, and to identify species that are associated with specific tillage systems. The ...

Biological abatement was used to condition dilute acid-pretreated hydrolysates of three perennial herbaceous crops that are potential bioenergy feedstocks: switchgrass, reed canarygrass, and alfalfa stems. Fungal isolate Coniochaeta ligniaria was inoculated into the hydrolysates to metabolize and remove inhibitory compounds prior to yeast fermentation of glucose. Switchgrass, reed canarygrass, ...
