In this study, impacts of different element absence (nitrogen, sulfur, phosphorus and magnesium) and supplementation (nitrogen and zinc) on element uptake and triacylglycerol production was followed in wild type Chlamydomonas reinhardtii CC-124 strain. Macro- and microelement composition of C. reinhardtii greatly differed under element regimes studied. In particular, heavy metal quotas of the m...

Chromium is an essential micronutrient which is required for normal insulin effect and regulation of blood sugar level. Serum chromium status of patients with type 2 diabetes was compared with control non-diabetic subjects. Blood samples were collected and serum glucose level of both groups was determined. The serum chromium concentration of samples was measured by flame-less atomic absorption ...

Mineral Fertilizers. It is considered to be the hall-mark of the good agriculturist that he aims not only to produce maximum crops, but to maintain the fertility of his soil unimpaired for the benefit of posterity. Both these ends were achieved in former times by the use of animal manures, by fallowing at regular intervals, and at a later date by the practice of crop rotation in conjunction wit...

Recent field experiments have shown that high chloride (Cl) in irrigation waters can increase soil cadmium (Cd) uptake by crops because of the formation of soluble ion-pair complexes of Cd with Cl in soil solution. The present study was aimed at testing a hypothesis that KCl in granulated PK fertilizers may enhance Cd uptake by crops from Cd-containing P fertilizers because of close contact bet...
