A green-house experiment was conducted to investigate the efficiency of three heavy metal-tolerant plant growth
promoting bacterial strains (HMT-PGPB) (Alcaligenes faecalis MG257493.1, Bacillus cereus MG257494.1 and
Alcaligenes faecalis MG966440.1 to alleviate the heavy metal’s toxic effects on sorghum plant (Sorghum bicolor,
L.) in addition to their ability to enhance plant growth. The oxidative enzymes, photosynthetic pigments, growth
characteristics, heavy metals uptake and heavy metals translocation factor (TF) were estimated in sorghum
cultivated in soil contaminated with heavy metals under green-house conditions. Results showed that the application
of these HTM-PGPB strains as biofertilizer of sorghum help plant to ignore the toxic effects of heavy
metals and enhance growth characteristics. |
