“…Chlorella sp. is a microgreen alga that is usually found in seawater ( Maghfiroh et al., 2018 ) C. vulgaris was cultivated in a photobioreactor with controlled conditions of NaCl that was extracted from salt from brackish and seawater ( Sahle-Demessie et al., 2019 ) Figure 1 a-b shows the suspension of Chlorella sp and Chlorella sp beads growth that was measured by optical density at 600 nm. The growth of immobilized cells reached a high level compared to fresh cells.…”
