“…The impact of IAA is plant-specific, since there are no advantages from IAA, to the bacterial cells. In a study performed by Kafrafi et al, 2017, they showed that in 7-day liquid bacterial cultures, the IAA levels were between 5 and 7 ppm [34]. This was analogous to our findings where we observed 5-6 ppm IAA in 5-day cultures (Figure 4).…”

“…PGPR mampu menghasilkan hormon tumbuhan seperti auxin, giberellin dan sitokinin, sebagai pelarut fosfat dan fiksasi nitrogen (Spaepen et al, 2009;Vessey, 2003). (Kafrawi et al, 2017) telah memformulasi PGPR mengandung isolat-isolat yang menghasilkan auksin, nitrogen, dan phosfor yang diinokulasi pada tanaman bawang merah dan memberi pengaruh baik terhadap jumlah daun dan jumlah umbi. Belum tersedia data tentang interaksi konsentrasi PGPR dengan takaran pupuk organik yang terbaik dalam memacu pertumbuhan tanaman bawang merah sehingga dipandang perlu untuk melakukan penelitian terkait hal tersebut.…”

“…Pengujian kemampuan isolat bakteri dalam menghasilkan IAA diukur secara kolorimetrik, dengan menggunakan media kultur NB yang ditambahkan L-triptofan, dan direaksikan menggunakan reagen Salkowski. Pemilihan media cair sebagai media pertumbuhan bagi isolat bakteri penghasil IAA didasarkan pada hasil penelitian Kafrawi et al (2017) yang melaporkan bahwa media cair dapat menyediakan nutrisi yang cukup untuk menopang proses pertumbuhan dan metabolisme selular bakteri.…”
