- Abstract
Microalgae from soil collected from rice paddies in San Juan, Batangas were identified. Samples of surface soil were diluted with floodwater and plated on BG11 and BG11-N, and the density of the microalgae were estimated to be 1.9 x 105 and 1.5 x 105 colony forming units per mL (CFU/mL), respectively. Unialgal and axenic cultures of the microalgae were isolated by culturing and streaking on solid BG11 and BG11-N media. Unialgal isolates of heterocystous cyanobacteria namely Nostoc humifusum Carmichael ex Bornet & Flahault, Nostoc linckia Bornet ex Bornet & Flahault, Nostoc piscinale Kützing ex Bornet & Flahault, Anabaena sphaerica Bornet & Flahault, and Scytonema hofmanni C. Agardh ex Bornet & Flahault were identified. Other isolates include cyanobacteria species of Oscillatoria, Calothrix, and another Nostoc species while two Chlorophyta species, i.e., Chlorella and Chlamydomonas, were also isolated.
