FOTOBIOREAKTORLAR QO’LLANILISHI
A photobioreactor (PBR) is a bioreactor that utilizes a light source to cultivate phototrophic microorganisms.[1] These organisms use photosynthesis to generate biomass from light and carbon dioxide and include plants, mosses, macroalgae, microalgae, cyanobacteria and purple bacteria. Within the artificial environment of a photobioreactor, specific conditions are carefully controlled for respective species. Thus, a photobioreactor allows much higher growth rates and purity levels than anywhere in nature or habitats similar to nature. Hypothetically, phototropic biomass could be derived from nutrient-rich wastewater and flue gas carbon dioxide in a photobioreactor.
Fotobioreaktor (PBR) - fototrof mikroorganizmlarni etishtirish uchun yorug'lik manbasidan foydalanadigan bioreaktor.[1] Bu organizmlar yorug'lik va karbonat angidriddan biomassa hosil qilish uchun fotosintezdan foydalanadi va o'simliklar, moxlar, makroalglar, mikroalglar, siyanobakteriyalar va binafsha bakteriyalarni o'z ichiga oladi. Fotobioreaktorning sun'iy muhitida tegishli turlar uchun o'ziga xos sharoitlar diqqat bilan nazorat qilinadi. Shunday qilib, fotobioreaktor tabiatning istalgan joyiga yoki tabiatga o'xshash yashash joylariga qaraganda ancha yuqori o'sish sur'atlari va tozalik darajasini beradi. Gipotetik jihatdan fototropik biomassani fotobioreaktorda ozuqa moddalariga boy oqava suv va tutun gazidan karbonat angidriddan olish mumkin.
What are the types of bioreactors? The major types are: (1) Continuous Stirred Tank Bioreactors. (2) Bubble Column Bioreactors. (3) Airlift Bioreactors. (4) Fluidized Bed Bioreactors. (5) Packed Bed Bioreactors.
Bioreaktorlarning qanday turlari mavjud? Asosiy turlari quyidagilardir: (1) Uzluksiz aralashtiriladigan tank bioreaktorlari. (2) Pufak ustunli bioreaktorlar. (3) Havo ko'tarish bioreaktorlari. (4) Suyuqlangan yotoqli bioreaktorlar. (5) Qadoqlangan yotoqli bioreaktorlar.
What is tubular photobioreactor?
Tubular photobioreactors are made of transparent tubing through which the culture is circulated at liquid velocities of typically 0.5 m s−1 [3]. To prevent high oxygen concentrations the transparent tubes are connected to a degasser or stripper vessel, where oxygen is removed by air injection
Quvurli fotobioreaktor nima?
Naychali fotobioreaktorlar shaffof trubadan yasalgan bo'lib, ular orqali kultura odatda 0,5 m s-1 suyuqlik tezligida aylanadi. Kislorodning yuqori konsentratsiyasini oldini olish uchun shaffof naychalar gazsizlantiruvchi yoki tozalovchi idishga ulanadi, bu erda kislorod havo in'ektsiyasi bilan chiqariladi.
What are closed photobioreactors?
Flat panel photobioreactors (FP-PBRs) are closed PBRs with a narrow light path and are characterized by large illuminated surface to volume ratio. These PBRs can be oriented into the direct path of light to obtain maximum exposure to solar energy

Which is not a photobioreactor?
A variation of this column system are annular photobioreactors, which consist of two glass or Plexiglas cylinders of different diameters placed one inside the other to form a culture chamber some 5–10 cm thick and 50–200 l in volume (Figure 3(e)). Illumination can be provided by either natural or artificial light.
Yopiq fotobioreaktorlar nima?
Yassi panelli fotobioreaktorlar (FP-PBR) tor yorug'lik yo'liga ega yopiq PBRlar bo'lib, katta yoritilgan sirt va hajm nisbati bilan tavsiflanadi. Ushbu PBRlar quyosh energiyasiga maksimal ta'sir qilish uchun yorug'likning to'g'ridan-to'g'ri yo'liga yo'naltirilishi mumkin.

Fotobioreaktor qanchalik katta?
Ushbu ustunlar tizimining o'zgarishi halqa shaklidagi fotobioreaktorlar bo'lib, ular qalinligi 5-10 sm va hajmi 50-200 l bo'lgan madaniyat kamerasini hosil qilish uchun bir-birining ichiga joylashtirilgan turli diametrli ikkita shisha yoki pleksiglas tsilindrlardan iborat (3-rasm (e)). ). Yoritish tabiiy yoki sun'iy yorug'lik bilan ta'minlanishi mumkin.
