Influence of elevated CO₂ concentrations on cell division and nitrogen fixation rates in the bloom-forming cyanobacterium <i>Nodularia spumigena</i>

In this context the influence of biofilm carriers in a MBR on the performance of organic matter and nitrogen removal and the influence on membrane fouling were evaluated..

Carbon (C) and nitrogen (N) stocks of particulate organic matter (POM) and mineral-associated soil organic matter (MAOM) as a function of N fertilization rates... The lower

To test the hypothesis that bacterial production can represent a significant part of the carbon fixation, principally in environments rich in organic matter, and that this

Remelted zone of the probes after treatment with current intensity of arc plasma – 100 A, lower bainite, retained austenite and secondary cementite.. Because the secondary

In Table 2, it can be seen that at all concentrations, the Simultaneous Treatment mitotic indices were statistically similar to the cell division indices of the Positive Control

The influence of nitrogen (N) limitation on the cell growth, chlorophyll content, intracellular lipid production and expression levels of two pathway genes in Chlorella

The aim of this work is to study the distribution and inter relationships of the organic matter, carbon, nitrogen and sulfur content in surface sediments of the Ubatuba Bay,

Levels of total soil organic carbon, as well as oxidizable fractions and aggregate stability, were analyzed, in addition to the activity and carbon and nitrogen content in the
