Summary: Although Azospirillum brasilense is commonly used in inoculant formulations, its prevalence in field conditions is still limited. In this study, A. brasilense was found in soil only at radicle emergency, and from the fifth day onwards, it was detected in roots at concentrations ranging from 10(3) to 10(5) CFU g(-1) of fresh root. This research provided a sensitive method for monitoring A. brasilense in field trials and offered new insights into the ecology of maize and A. brasilense interaction.

Summary: The research describes a new method for screening and identifying bacterial consortia that promote the growth of corn. This method utilizes a microfabricated high-throughput screening device, called the microwell recovery array (MRA), to explore the maize rhizobiome for combinations of bacteria that enhance the growth and colonization of the nitrogen-fixing PGPB, Azospirillum brasilense. The study found that bacterial consortia dominated by bacteria from the Acinetobacter-Enterobacter-Serratia genera significantly accelerated the growth of corn plants when co-inoculated with A. brasilense. This research demonstrates a rapid bioprospecting method for identifying complementary PGPB and developing next-generation biofertilizers.

Summary: The effects of nitrogen fertilization and inoculation with Azospirillum brasilense on the quality of Cantaloupe melon fruit were evaluated in this study. Two experiments were conducted, one with direct sowing and the other with transplanted seedlings, using a 2 x 2 factorial scheme with five replications. The biometric variables of the fruits were evaluated, including fresh weight, longitudinal and transverse diameters, skin and pulp thickness, soluble solids content and titratable acidity. Nitrogen fertilizer and A. brasilense increased the biometric variables of the fruits for transplanted seedlings, while the effect of nitrogen sources was significant in terms of the organoleptic characteristics of melon fruits when direct sowing was carried out. The use of nitrogen fertilizer and A. brasilense for transplanted seedlings and A. brasilense for plants sown directly is necessary to improve the development, productivity and quality of Cantaloupe melon fruit.

Summary: The inoculation of maize with Azospirillum brasilense has shown significant increases in root mass, N leaf concentration, grain yield, and N in grains. The benefits of inoculation were higher at lower yields and lower N rates, with seed inoculation being more efficient than leaf-spray inoculation.

Summary: Bioavailable nitrogen is crucial for agricultural food production, and engineered diazotrophs show potential for plant growth promotion. However, balancing ammonia production rates and fitness defects is important. Multi-copy stable strains of Azospirillum brasilense exhibit improved plant growth promotion in hydroponic conditions, but their effectiveness in nonsterile soil may be limited.

Summary: The presence of arsenic in groundwater poses a potential agronomic problem by accumulating in the food chain. Using plant growth-promoting bacteria (PGPB) is an important tool to reduce metal toxicity. When maize plants were exposed to arsenate, different strains of bacteria led to morphological changes in root exodermis, decreased photosynthetic pigments, and induced oxidative stress, with differential antioxidant responses observed.

Summary: This study investigated the combined effects of nitrogen application levels and Azospirillum brasilense inoculation on maize plant biomass, grain yield, agronomic efficiency, and nitrogen content in plants. The results showed that inoculation with A. brasilense enhanced agronomic efficiency and nitrogen uptake in maize plants, leading to increased grain yield. In addition, the study found that it is possible to reduce nitrogen fertilization levels and increase operating profit with A. brasilense inoculation. Therefore, inoculation with A. brasilense has the potential to improve plant-soil nitrogen management and promote sustainable maize production, with its low cost and ease of application.

Summary: Azospirillum inoculation is an effective strategy for promoting sustainable agriculture and enhancing crop productivity. This study evaluated the application of different doses of Azospirillum inoculant in sugarcane and found that higher doses increased the stalk population and yield, as well as sugar and energy production. These findings suggest that high-dose Azospirillum inoculation can maximize agronomic and economic benefits in the sugarcane sector.

Summary: Nitrogen is the most important nutrient for potato and cassava crops, and Azospirillum brasilense can enhance their growth. Field experiments were conducted to investigate the effects of A. brasilense inoculation and mineral nitrogen application on plant growth, nitrogen uptake, and leaf nitrogen concentration in both natural and disinfected soil. The results showed that inoculating A. brasilense increased leaf nitrogen concentration in potato plants, but did not significantly improve plant growth or nitrogen uptake. However, in cassava, A. brasilense inoculation increased leaf nitrogen concentration and shoot biomass, especially when nitrogen was supplied. In disinfected soil, A. brasilense inoculation also increased cassava nitrogen uptake. Conversely, in natural soil, A. brasilense minimized the negative effects of excessive nitrogen on cassava tuber development. These findings suggest that A. brasilense may be a more effective option for improving nitrogen status and growth in cassava compared to potato.

Summary: The Gram-positive bacterium Lacticaseibacillus rhamnosus has been shown to have beneficial health effects. In this study, we investigated the genomic diversity and gene distribution patterns of L. rhamnosus strains. We found that L. rhamnosus has a diverse pangenome and can be classified into eight phylogroups. Certain phylogroups showed highly conserved gene distribution patterns, while others exhibited more variability. Our findings shed light on the distribution of biotechnologically relevant genes in L. rhamnosus populations, which can be useful for the development of more efficient probiotic products.

Summary: The genus Herbaspirillum has gained attention for its potential diazotrophic strains and beneficial effects on plant growth. However, further exploration revealed that this genus is not limited to plant beneficial interactions, but also involved in phytopathogenesis and nosocomial infections. Through genome analysis and phylogenetic study, we found that all described Herbaspirillum species are well defined, except for H. aquaticum and H. huttiense. We also discovered that the nif genes are highly prevalent in H. rubrisubalbicans, but share a similar gene arrangement and ancestral origin with other Herbaspirillum species.

Summary: This study evaluated the bioaccessibility and synergistic effects of polyphenols in cowpea beans and orange juice through in vitro co-digestion. The results showed that cooking and solvent extraction affected the concentrations of polyphenols in cowpea beans, and thermal treatment enhanced their bioaccessibility. Co-digestion of cowpea beans and orange juice increased the content of bioaccessible phenolics and promoted positive interactions between polyphenols.

Summary: The use of commercial bacterial inoculants formulated with plant-growth promoting bacteria (PGPB) in agriculture has become prominent in recent years. However, the effectiveness of these inoculants may be compromised due to the decrease in bacterial cell viability during use. This review provides an overview of research on selecting sublethal stress strategies to increase the effectiveness of bacterial inoculants. The use of sublethal stress, such as osmotic, thermal, oxidative, and nutritional stress, can enhance the survival and performance of bacterial inoculants, leading to improved plant development and disease control.
