Abstract
Rhodopseudomonas palustris is a very beneficial bacteria to
humans. These bacteria are able to absorb carbon from the
environment, degrade toxic compounds, also produce natural
dyes. Because of its usefulness, many researchers are
interested to do further study. From what they were doing,
biomass becomes an important factor when analyzing the
optimization of the bacteria production. During the years, the
researchers calculate a such productivity using cell biomass
extraction technique which is somewhat time consuming.
From this background, in this study will be correlated both the
Rhodopseudomonas palustris bacteria growth pattern and its
protein spectra that were measured by NIR Spectroscopy.
From this research results, I expect to facilitate the acquisition
of cell biomass without any extraction procedures.
