Growth of and the capacity to take up nitrogen in the freshwater microalgae Chlorella vulgaris were studied while varying the concentrations of ammonium and nitrate, the pH and the source of carbon in a synthetic wastewater growth medium when co-immobilized in alginate beads with the microalgae growth-promoting bacterium Azospirillum brasilense. Analyses of 29 independent experiments showed tha...

Abstract This study was aimed to investigate response of two sweet corn hybrids bacterial biofertilizers and spraying with Mg +2 Ca their impact on the yield during fall season 2021, CASH seeds (H1) ROI SOLEIL (H2) were planted in pots, when they reached 2-3 leaves treated four treatments which included without biofertilizer (B0), Azospirillum brasilense (B1) Pseudomonas fluorescens (B2) intera...

Azospirillum has been shown to improve coleoptile growth in seedlings growing in darkness under osmotic stress. However, the changes in water relations that may occur in this experimental system have not yet been studied. Two-centimetre long Triticum aestivum cv. Buck Pucará and Triticum durum cv. Balcarceño-INTA seedlings were inoculated with viable or autoclaved (control) Azospirillum brasile...

This study evaluated the combined effect of foliar spray inoculation with plant growth-promoting bacteria (PGPB) and nitrogen doses on yield, development, nutritive value Megathyrsus maximus cv. BRS Zuri. The experimental design was randomized blocks four replications, repeated measures in time. Foliar two (Azospirillum brasilense Ab-V5 (CNPSo 2083) Ab-V6 2084) Pseudomonas fluorescens 2799)) 40...

Mixed cultures of Cellulomonas gelida plus Azospirillum lipoferum or Azospirillum brasilense and C. gelida plus Bacillus macerans were shown to degrade cellulose and straw and to utilize the energy-yielding products to fix atmospheric nitrogen. This cooperative process was followed over 30 days in sand-based cultures in which the breakdown of 20% of the cellulose and 28 to 30% of the straw resu...

Three strains of the freshwater microalgae used for wastewater treatment, Chlorella vulgaris and Chlorella sorokiniana co-immobilized separately in alginate beads with the microalgae-growth-promoting bacterium Azospirillum brasilense Cd, resulted in significant changes in microalgal-population size, cell size, cell cytology, pigment, lipid content, and the variety of fatty acids produced in com...

Root nodule isolates from a shrubby legume, Lotononis bainesii, were characterized by 16S rRNA gene sequencing and morphologically by substrate utilization patterns. The symbiotic genome of these isolates was analysed by partial sequencing of the nifH gene. Based on the results of numerical taxonomy, the isolates formed a closely related cluster, showing no correspondence to any of the known rh...

Owing to its cell form, growth behavior and habitat within grass roots, the first isolates of the later defined genus Herbaspirillum were initially thought to be a new Azospirillum species (Baldani et al., 1984). However, RNA-RNA hybridization experiments showed no close relatedness with Azospirillum spp. or Aquaspirillum itersonii (Falk et al., 1986). The first species of the newly defined gen...
