Description
Summary:Serratia plymuthica UBCF_13 is a group of bacteria that is capable of producing the hormone Indole-3-Acetic Acid (IAA) which plays an important role in plant physiological processes. IAA production in bacteria is influenced by several factors, one of them being culture duration. This study aimed to determine the optimum duration of IAA production in the bacterium Serratia plymuthica UBCF_13 on YEM media with the addition of 300 µg/mL L-Tryptophan. Determination of the optimum time for IAA production was carried out with differences in 24 hours, 48 hours, 72 hours, and 96 hours and the presence or absence of the addition of Calcium metal [Ca]. The results of this study showed that the bacteria Serratia plymuthica UBCF_13 produced IAA optimally at a 24-hours culture duration of 107.84 µg/mL with Ca ion addition.
