The study was descriptive research. The study aimed to determine the best initial growth pH for <em>Leptolyngbya </em>HS (Hot Spring)-16 and HS-36. <em>Leptolyngbya </em>HS-16 was isolated from Pancar Mountain hotspring, while <em>Leptolyngbya</em> HS-36 was isolated from Maribaya hot spring.  The acidity (pH) of Pancar mountain and Maribaya hot spring was 7. Each strain was grown in Blue Green medium number 11 (BG-11) with variation initial pH (6, 7, 8 and 9) and incubated on 35 <sup>o</sup>C. Parameters was wet biomass weight of <em>Leptolyngbya </em>in each strain. Observation were made on 15 days with 11 sampling. From the observation, the average of wet biomass weight of <em>Leptolyngbya</em> HS-16 was obtained at pH 6 (0,0295 g/L), pH 7 (0,0404 g/L), pH 8 (0,03825 g/L), and pH 9 (0,02735 g/L), meanwhile <em>Leptolyngbya</em> HS-36 was obtained at pH 6 (0,02905 g/L), pH 7 (0,01995 g/L), pH 8 (0,05345 g/L) and pH 9 (0,05995 g/L) on the 15<sup>th</sup> day. The results of 15 days observation showed that the best initial pH for growing <em>Leptolyngbya </em>HS-16 is 7, while <em>Leptolyngbya </em>HS-36 is 9. From this study it could be seen that <em>Leptolyngbya </em>HS-16 and HS-36 could be cultured with alkaline condition. </p>}, number={3}, journal={Microbiology Indonesia}, year={2019}, month={Jan.}, pages={1} }
