Vitamin D enhanced pork from pigs exposed to artificial UVB light in indoor facilities

“…A feasible strategy is to fortify a broader range of foods and/or increase the natural content of vitamin D in foods, e.g. fatty fish, eggs and meat [4,7,8].…”

Light assisted antibiotics

“…The spectrometer used was a SPECTRO 320 (D) Release 5 (Instrument Systems GmbH). The exact protocol for measuring the spectral irradiance can be found in Barnkob et al [51]. The irradiance delivered on the biofilms was measured with a portable radiometer (NIST Certified UV Radiometer) at a distance (1.5±0.1cm).…”

Inactivation of Pseudomonas aeruginosa biofilm after ultraviolet light-emitting diode treatment: a comparative study between ultraviolet C and ultraviolet B

“…The spectrometer coupled to the monochromator was a SPECTRO 320 (D) Release 5 (Instrument Systems GmbH). Details about the irradiation measurements protocol can be found in Barnkob et al 18 The irradiance delivered on the biofilms was also cross confirmed with a portable radiometer (NIST-certified UV radiometer); the distances the irradiance measurements were taken (1.5 AE 0.1 cm) were the same distances that the exposures were conducted.…”
