nutrient - any substance (such as a chemical element or inorganic compound) that can be taken in by a green plant and used in organic synthesis substance - a particular kind or species of matter with uniform properties; "shigella is one of the most toxic substances known to man" water - ...
Little is known about the responses of heterotrophic microorganisms, espe- cially aquatic fungi, to these shifts in nutrient availability. Apart from limiting the metabolic activity of microorganisms, N and P can also affect nutrient content of microbial biomass. Demand from microorganisms for energy ...
(Hirai et al., 2004). Other motivations in relation to the technology of hydroponic cultivation are higher yield per area, lower incidence of pests and diseases, easier implementation of cultural dealings, better production scheduling, and shorter cycles, as a result of better environmental control...
K562 cells grown in complete RPMI were washed 3× using cycles of centrifugation for 5 min at 300g and resuspension of the cell pellet in phosphate-buffered saline (PBS, Corning 21–040 CV). The final cell pellet was first resuspended in PBS at a density of 10 million ml−1 ...
Freshwater snails are also intermediate hosts for a variety of parasites of medical and veterinary significance.Biofilm assemblages are patch scale communities which dominate the metabolism and biogeochemical cycles in stream ecosystems. To determine the effects of eutrophication, one of the most common ...
Another recurring result is that world rivers export to estuarine zones nearly 25% of the terrestrial N excess, whereas similar calculations for P lead to variable low percentages (1–14%), likely due to the complex retention/release mechanisms for elements with sedimentary cycles. There is a gr...
This is called the Comparative Relative Maturity (CRM) and is commonly referred to as the days from planting to physiological maturity (also known as black layer). However the actual number of days taken to reach black layer will vary greatly with location, planting time, and other ...
Only such an approach enables the integration of BSFL into agro-ecological systems to close nutrient cycles as efficiently as possible. The objective of this paper is to present the current knowledge on growth potential, feed efficiency, respiratory gas exchange, and intestinal biology of BSFL with...
known to cover a broad taxonomic range and have a high resolution for coastal marine bacteria49. PCR reactions were performed in triplicate using BioRad S1000 (Bio-Rad Laboratory, Hercules, CA, USA). The thermocycling was: 5 min at 94 °C for initialization; 30 cycles of 30 s dena...
vOTUs clustered with known temperate phages during vConTACT2 clustering or representing proviral sequences were assigned as temperate [25]. All other vOTUs were assigned as lytic, even though the absence of temperate phage-associated proteins could have also been due to incompleteness of viral genom...
