Acidobacteria strains were tested for their ability to solubilize a mineral form of phosphate. P. putida IAC-RBal4 was used as a positive control. Tests were performed on the National Botanical Research Institute’s phosphate growth medium (NBRIPM) containing per liter 15 g agar–agar ultrapure (Merck KGaA), 10 g glucose, 5 g Ca3(PO4)2, 5 g MgCl2·6H2O, 0.25 g MgSO4·7H2O, 0.2 g KCl and 0.1 g (NH4)2SO4 (Nautiyal 1999 (link)). All strains were inoculated by transfer from the 0.1 × TBA pH 5.0 media using inoculation loop and incubated for 6 weeks at 20 °C. The clearing zones around the colonies indicated phosphate solubilization by the isolates. The experiment was carried out in triplicate on separate plates.
Agar agar ultrapure
Agar-agar ultrapure is a highly purified form of agar, a natural gelling agent derived from red seaweed. It is a neutral, odorless, and colorless polysaccharide that forms a firm, transparent gel when dissolved in water and cooled. The core function of agar-agar ultrapure is to serve as a solidifying and gelling agent in various laboratory applications.

Arabidopsis Growth Conditions for Epigenetic Studies
For the Dark/Light set, seeds from wild-type (WT) Col-0 arabidopsis plants were surface-sterilized, plated on filter papers lying on MS medium supplemented with 0.9% agar and exposed to either a 16-/8-h (23/19 °C) white light/dark photoperiod or constant dark conditions (wrapped in 3 layers of aluminum foil). White light is generated by fluorescent bulbs (100 μmol·m−2·s−1). Seedlings are harvested under light condition or under safe green light for the dark condition [35 (link)].

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
