A light-wind-heat coupling reinforced hot spring thermophilic blue-green algae culture photobioreactor

Abstract

This invention discloses a photobioreactor for enhanced cultivation of thermophilic cyanobacteria in hot springs, comprising a reactor body, a light source system, a floating supply device, an attachment device, a control system, and an energy supply system. The reactor body is connected to the energy supply system, utilizing light and wind energy to supply energy to the reactor body. A floating supply device is located at the bottom of the reactor body to provide sufficient CO2 and other nutrients for the thermophilic cyanobacteria. An insulation cylinder is installed inside the reactor body to significantly reduce heat dissipation within the bioreactor. An attachment system is installed inside the reactor to recreate the attachment habitat of the thermophilic cyanobacteria in the hot spring while facilitating subsequent recovery. In this invention, the environmental conditions required for the growth and reproduction of thermophilic cyanobacteria in hot springs can be automatically controlled under low-carbon and clean conditions, providing a reliable solution for the large-scale ex-situ cultivation of thermophilic microorganisms.
