Canadian Council of Ministers of the Environment, 2012 he nitrate ion (NO3) (CAS No. 14797-55-8, atomic mass 62.0049 g·mol) is the most oxidized form of nitrogen (N) present in the environment with an oxidation state of +5 (NRC 1978). It is the conjugate base of nitric acid (HNO3), a strong acid which is completely dissociated in solution (NRC 1978). The nitrate salts of all common metals (e.g....

the use of nitrogen in nutrient media is essential for growth and helps identify highly productive media for potato (solanum tuberosum l.) micropropagation and adventitious shoot formation. three potato cultivars (agria, marfona and savalan cultivars) were examined for their growth response with medium containing four different levels of kno3 (1, 1.25, 1.5 and 1.75 times as much 1.9 g l-1) and ...

We introduce the additives effect in molten salts such as commercially pure KNO3 and polluted KNO3. The results showed that case of commercial purity KNO3, only KOH improved compressive stress (CS) ion-exchanged glasses up to ∼50 MPa, others did not make CS improvement. Rather than was diminished by additive contamination. In contaminated K3PO4, K2CO3, K2SO4 successfully removed impurities, Na+...

background: purple coneflower (echinacea purpurea l.) is one of the most important medicinal plants. hairy root culture of echinace, represent a valuable alternative to field cultivation for the production of bioactive secondary metabolites. objective: the present study investigates the effects of kno3, cacl2 and mgso4 concentrations on growth and the biosynthesis of cichoric acid in echinacea ...

Background: Purple coneflower (Echinacea purpurea L.) is one of the most important medicinal plants. Hairy root culture of Echinace, represent a valuable alternative to field cultivation for the production of bioactive secondary metabolites.

Nitrogen plays a pivotal role in growth and differentiation of cells of Phyllanthus amarus Schum. and Thonn. Both form and amount of nitrogen in nutrient medium have significant effects on the rate of cell growth and differentiation. In this study, effects of different inorganic nutrients (KNO3 and NH4NO3) and organic nutrients (glycine) on regeneration of P. amarus were evaluated. Murashige an...

Problem statement: In today’s scenario, microalgae are widely recognized as a promising source for biofuel production as a renewable source of energy. They are exceedingly rich in oil, which can be converted to biofuel. This paper deals with one of the method to enhance the lipid content in microalgae. Approach: Microalga, Chlorella pyrenoidosa, was grown autotrophically in batch culture and th...
