Przedmiotem wynalazku jest sposób wytworzenia naturalnego aktywnego biologicznie kompozytu otrzymanego z jednokomórkowych mikroalg z rodzaju Planktochlorella sp. jako modulatora wzrostu mikroorganizmów mogącego mieć zastosowanie w przemyśle kosmetycznym oraz farmaceutycznym przy wykorzystaniu zjawiska fotoreprogramowania metabolizmu. Przedstawiona w tym zgłoszeniu technologia do tej pory nie była stosowana w odniesieniu do hodowli mikroalg z rodzaju Planktochlorella sp. i opiera się na wykorzystaniu fotomodulacji to jest działaniu określonych warunków świetlnych (źródło, natężenie światła, długość fali, czas oświetlenia) w celu reprogramowania metabolizmu glonów i w konsekwencji otrzymaniu kompozytu o porządanych cechach. Opracowana w tym celu procedura zgodnie z wynalazkiem charakteryzuje się tym, że hodowlę jednokomórkowych mikroalg prowadzi się w całodobowym oświetleniu z zastosowaniem diod typu LED jako źródła światła czerwonego (z dominującą długością fali 645 nm) i niebieskiego (z dominującą długością fali 460 nm) w stosunku 3:1 oraz łącznym natężeniu 16000 LUX tj. 1419 µmol m-2 s-1, co pozwala uzyskać kompozyt o następującym składzie biochemicznym: zawartość tłuszczu - 10.11 g/100 g biomasy, zawartość białka - 59.78 g/ 100 g biomasy, zawartość chlorofilu a - 15.42 mg/l, zawartość chlorofilu b - 4.40 mg/l, zawartość karotenoidów - 1.77 mg/l, suma nasyconych kwasów tłuszczowych (SAFA) - 77,4%, suma j

A new alga having an improved ability to produce a pigment is disclosed. When the new alga is used, a carotenoid-based pigment, specifically, a xanthophyll can be produced by consuming less energy, so that it is possible to efficiently produce the pigment at the industrial level. The pigment can be applied as a raw material for a food, a health functional food and a medicine, which include the pigment. Since a DNA fragment is not likely to be inserted into a target base sequence or a base sequence other than the target, it is expected that the procedure of constructing the mutant is not regulated as a GMO, so that it is expected that the procedure of constructing the mutant can create a big economic effect in terms of an industry which produces lutein and zeaxanthin by using microalgae.
