(1999). How do soil organisms affect total organic nitrogen storage and substrate nitrogen to carbon ratio in soils? A theoretical analysis. Oikos 86: 430-442.Zheng, D.W., AE gren, G.I., Bengtsson, J., 1999. How do soil organisms affect total organic nitrogen storage in soils and ...
This diterpene is known to exhibit variable interesting pharmacological activities including anti-inflammatory, cytotoxic, anti-bacterial, anti-parasitic, anti-angiogenic and anti-oxidative activities but suffers from very low bioavailability as a result of its extremely low water solubility. Cryptotanshinone...
Mycorrhizal strategies are very effective in enhancing plant acquisition of poorly-mobile nutrients, particularly phosphorus (P) from infertile soil. Howev
Discovery and study of different bacterial resistance strategies as well as the development of new antimicrobial compounds, which are also able to overcome the protecting outer-membrane barrier of Gram-negative bacteria, are of great urgency1. Albicidin is a phytotoxic small molecule synthesized by ...
Finding nitrogen fixation in the sediments was surprising and also a bit worrisome. Most organisms cannot fix nitrogen and it has long been thought that this process was generally not important in marine sediments. What would cause this dramatic shift? And what might it mean for estuaries and th...
Electrohypersensitivity may be a remnant of the evolutionary responses of living organisms to electromagnetic fields — particularly magnetic fields — in the environment. Similarities include responsiveness to very low-field intensity; the response is persistent and built into the physiology of an ...
Gellan gum is similar toxanthan gumin that it is an exopolysaccharide produced by bacterial fermentation. Unfortunately, the routine animal toxicity studies conducted for new food additives aren’t available online, but we do have a human study to look at. To test the safety of gellan gum, the...
We may be treating our sewage and our runoff better than we used to, but we’re still dumping massive amounts of nutrients --nitrogen, phosphate, and iron -- from our waste into the water. For Santa Monica Bay, the value of this nutrient input from treated sewage and stormwater ...
These results are explained by Abedon’s rationale, when he suggests that as the virulent phages disrupt more and more bacterial hosts the number of susceptible host cells decreases [44], which places a burden on the phages, as if they do not find sufficient host cells to infect they face...
Initially, samples previously frozen (−20 °C) to avoid the oxidation of plant material were vigorously macerated in liquid nitrogen with a mortar and pestle until the formation of a slightly whitish powder. Approximately 400 mg of the macerate was transferred to 2 mL microtubes containing 700...
