Cold-adapted strains as plant growth-promoting bacteria on soybean seeds and biocontrol agents against Macrophomina phaseolina.

Aim: The aim was to characterize cold-adapted bacteria by testing their PGP features and antagonistic activity against Macrophomina phaseolina, both in vitro and coating soybean seeds (Glycine max [L.] Merr.).

Burkholderia gladioli MB39 an Antarctic Strain as a Biocontrol Agent.

Bioprospecting sub-explored environments such as Antarctic locations leads to finding out diverse activities, reducing harmful chemical usage that affects both human health and the environment. In this study, ~ 7000 cold-adapted bacterial strains were isolated from samples around Melchior Antarctic Base at 5 °C and more than 13,000 at 15 °C. Out of them, 900 different colony morphotypes were evaluated for antimicrobial production, and 13 isolates demonstrated antibacterial and antifungal activities.
