The ATCC 2107 medium comprised the following (per liter of deionized water): 10 g peptone, 10 g beef extract, 3 g yeast extract, 5 g glucose, 5 g NaCl, 3 g sodium-acetate, 1 mL azure (0.025%), 0.5 g Cys-HCl, pH 6.8.
The cells were then washed three times in DMEM F12 medium and were resuspended in mammosphere culture medium comprising DMEM F12 with the serum replacement supplement B27 (Invitrogen, Paisley, UK) and hydrocortisone, insulin, epidermal growth factor and bovine pituitary extract (SingleQuots; Cambrex Bio Science, Nottingham, UK).
In this model, mixture multiphase model is used to describe the flow of the dense medium (comprising finely ground magnetite contaminated with non-magnetic material in water) and the air core, where the turbulence is described by the well-established Reynolds Stress Model.
To establish growth of S. aureus in liquid medium in the presence of UE-12, the liquid medium, comprising 20% S. aureus culture and 80% M9 buffer, was prepared as described above.
In DMEM/F12 culture medium comprising 10% fetal bovine serum (FBS), the average hydrodynamic diameter of the NPs was 10 ± 4 nm, as measured by dynamic light scattering (DLS).
Similar practice was followed in consecutive three batches where the remaining 3 mL of medium comprising induced cells was castoff as inoculum.
Following 1.5 h incubation in a shaking water bath at 37°C, the cell suspension was filtered through a 40 µm mesh (Fisher Scientific, Loughborough, UK) to remove undigested material and the filtrate was resuspended in washing medium, comprising of HBSS with 10% fetal bovine serum (FBS, Sigma).
Electroanalysis in a non-aqueous medium comprising acetonitrile (ACN) and tetrabutylammonium hexafluorophosphate (TBAH) is capable of separating the oxidation peak of TRP from that of indole.
Since calli on the above three multiplication media remained dedifferentiated, to achieve regeneration, ovary calli from the above three media were transferred to MS medium comprising different combinations and concentrations of BAP, IAA and CH.
