Ebook "Iron nutrition in plants and rhizospheric microorganisms" provides comprehensive reviews on topics of plant-iron nutrition that are being addressed by different laboratories around the world. As one can see, the area of plant-iron nutrition is highly interdisciplinary, involving scientists of various fields of knowledge. Plant biologists are needed to characterize iron translocation throughout the plant following root iron uptake and to examine the regulation of iron-stimulated activities that influence crop yield and quality.

Microorganisms in the rhizosphere soil play a key role in maintaining the soil fertility, which is a key for successful crop production to meet the increasing global food demand. The aims of this study were to boost growth attributes, yield and nutrient uptake of rice by different treatment combination of plant growth promoting bacteria (PGPB) and NPK fertilizer doses.

The research article "Polyester production by halophilic and halotolerant bacterial strains obtained from mangrove soil samples located in Northern Vietnam" reports halophilic and halotolerant bacteria isolated from mangrove forests located in Northern Vietnam. Several of these bacteria were able to synthesize polyhydroxyalkanoates (PHAs). PHAs are polyesters stored by microorganisms under the presence of considerable amounts of a carbon source and deficiency of other essential nutrient such as nitrogen or phosphorous.

Vermicompost contains beneficial bacteria, vermicompost is a finely divided peat-like material with high porosity, good ventilation, drainage, water-holding capacity, microorganism activity, Excellent nutritional status and buffering capacity thus provide the physiological properties required for soil fertility and plant growth. Worm manure enhances soil biodiversity by promoting entry and enhances plant growth directly by producing plant growth-regulating hormones and enzymes.

The degradation characteristics of phenanthrene (Phe), pyrene (Pyr) and benzo[a]pyrene (BaP) in freeze-thawed soil by both co-immobilized and free microorganism were studied. The removal rate of Phe, Pyr and BaP using the co-immobilized fungal-bacterial consortium within 60 d was 59.2±3.7%, 46.6±3.3%, and 36.8±2.7%, respectively, which was obviously higher than that of free fungal-bacterial consortium in the same time.

The main PGP-properties, namely the ability to solubilize-P and production of IAA, as well as production of siderophores and HCN were examined. Additionally, field trials were conducted on sandy loam soil at El-Tahrir Province during two successive summer seasons to study the effect of co-inoculation with Bradyrhizobium either individually or together with S. marcescens and/or T. harzianum on nodulation

In the present study, microalgal biomass (Anabeana circinalis and Scenedesmus quadricauda) was used as biofertilizer in cucumber cultivation. The response of cucumber growth characters to microalgal biofertilizer was evaluated. Moreover, rhizosphere microbial diversity and community composition of cucumber was analyzed through 16S rRNA high-throughput Illumina sequencing data. The results showed that microalgal biomass as biofertilizer significantly promoted height, number of leaves and flower buds, and stem diameter of cucumber. The application of a high concentration of S.

This study presents the synthesis of glucose-based surfactants including quaternary ammonium salts. Their surface properties and influence on the soil environment were investigated. The synthesized quaternary ammonium chlorides of glucose-based ester exhibited good surface tension reduction properties and formed stable foam in contact with water. The results showed that quaternary ester ammonium salts affect the activation of metals (nickel and cadmium) from the soil matrix after their introduction into the soil environment. This phenomenon can increase the bioavailability of these metals.
