通过温室试验，研究了3株耐重金属植物生长促生菌(HMT-PGPB)(粪产碱菌MG257493.1、蜡状芽孢杆菌MG257494.1和粪产碱菌MG966440.1)对高粱(Sorghum biolor，L.)除了它们促进植物生长的能力之外。在温室条件下，对重金属污染土壤中种植的高粱的氧化酶、光合色素、生长特性、重金属吸收和重金属转移因子(Tf)进行了测定。结果表明，这些HTM-PGPB菌株作为高粱生物肥料的应用有助于植物克服重金属的毒害作用，提高植株的生长特性。
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.
