Polyhydroxyalkanoates (PHAs) are a group of carbon andenergy storage compounds that are accumulated during suboptimal growth by many bacteria, and intracellularly deposited in the form of inclusion bodies. Accumulation of PHAs is thought to be used by bacteria to increase survival and stress tolerance in changing environments, and in competitive settings where carbon and energy sources may be l...

Metal hyperaccumulator plants like Alyssum murale have a remarkable ability to hyperaccumulate Ni from soils containing mostly insoluble Ni. We have shown some rhizobacteria increase the phytoavailability of Ni in soils, thus enhancing Ni accumulation by A. murale. Nine bacterial strains, originally isolated from the rhizosphere of A. murale grown in serpentine Ni-rich soil, were examined for t...

High growth rates and rapid reproductive development associated decline in feed quality of sown tropical perennial grass pastures present management challenges for livestock producers. Conservation surplus forage as silage could be an effective tool. Experiments were conducted to evaluate the fermentation silages produced from grasses. Five species (Chloris gayana, Megathyrsus maximus, Panicum ...

Bacterial and fungal endophytes are widespread inhabitants inside plant tissues and have been shown to assist plant growth and health. However, little is known about plant growth-promoting endophytes (PGPE) of medicinal plants. Therefore, the aims of this study were to identify bacterial and fungal endophytes of Teucrium polium and to characterize plant growth-promoting (PGP) properties of thes...

Phosphate solubilizing bacteria (PSB) can convert insoluble form of phosphorous to an available form. Applications of PSB as inoculants increase the phosphorus uptake by plant in the field. In this study, isolation and precise identification of PSB were carried out in Malaysian (Serdang) oil palm field (University Putra Malaysia). Identification and phylogenetic analysis of 8 better isolates we...

The concept of using cultures of lactic acid bacteria to enhance silage fermentation developed near the beginning of the last century but early cultures had insufficient bacteria and little success until freeze drying and encapsulation techniques were developed (Weinberg and Muck, 1996). Traditional silage inoculants were developed to acidify crops during anaerobic storage and thereby minimize ...

Bacterial inoculants are known to possess plant growth promoting abilities and have potential as liquid biofertilizer application. Four phytase producing bacterial isolates (phytase activity in the range of 0.076-0.174 U/mL), identified as Advenella species (PB-05, PB-06, and PB-10) and Cellulosimicrobium sp. PB-09, were analyzed for their plant growth promoting activities like siderophore prod...

Proving of rhizobia’s other abilities in spite of Nitrogen fixation ability and considering these bacteria as plant growth promoting rhizobacteria (PGPR), researching tasks in this field have increased. Now, it’s completely proved that we can find such strains among many more strains of each rhizobial group that can also do effective process in plant growth promoting as plant growth hormones pr...
