Selection and Effect of Plant Growth-Promoting Bacteria on Pine Seedlings ( and ).

Forest cover is deteriorating rapidly due to anthropogenic causes, making its restoration urgent. Plant growth-promoting bacteria (PGPB) could offer a viable solution to ensure successful reforestation efforts. This study aimed to select bacterial strains with mechanisms that promote plant growth and enhance seedling development.

The Viable but Non-Culturable (VBNC) State, a Poorly Explored Aspect of Beneficial Bacteria.

Many bacteria have the ability to survive in challenging environments; however, they cannot all grow on standard culture media, a phenomenon known as the viable but non-culturable (VBNC) state. Bacteria commonly enter the VBNC state under nutrient-poor environments or under stressful conditions. This review explores the concept of the VBNC state, providing insights into the beneficial bacteria known to employ this strategy.

Optimization of sp. NMA1017 Application as a Biocontrol Agent for and in Cacao-Growing Fields in Chiapas, Mexico.

In Mexico, cacao production is endangered by pathogenic fungi, such as spp. and that cause black pod rot and moniliasis, respectively. In this study the biocontrol agent sp.

Structural characterization of scorpion peptides and their bactericidal activity against clinical isolates of multidrug-resistant bacteria.

Scorpion venom peptides represent a novel source of antimicrobial peptides (AMPs) with broad-spectrum activity. In this study, we determined the minimum bactericidal concentration (MBC) of three scorpion AMPs, Uy234, Uy17, and Uy192, which are found in the venomous glands of the Urodacus yaschenkoi scorpion, against the clinical isolates of multidrug-resistant (MDR) bacteria. In addition, we tested the activity of a consensus AMP designed in our laboratory based on some previously reported IsCT-type (cytotoxic linear peptide) AMPs with the aim of obtaining higher antimicrobial activity.

Desiccation-induced viable but nonculturable state in Pseudomonas putida KT2440, a survival strategy.

The potential of Pseudomonas putida KT2440 to act as a plant-growth promoter or as a bioremediator of toxic compounds can be affected by desiccation. In the present work, the bacterial survival ratio (BSR) in response to air desiccation was evaluated for P. putida KT2440 in the presence of different protectors.

Compatible bacterial mixture, tolerant to desiccation, improves maize plant growth.

Plant growth-promoting rhizobacteria (PGPR) increase plant growth and crop productivity. The inoculation of plants with a bacterial mixture (consortium) apparently provides greater benefits to plant growth than inoculation with a single bacterial strain. In the present work, a bacterial consortium was formulated containing four compatible and desiccation-tolerant strains with potential as PGPR.

Next generation of microbial inoculants for agriculture and bioremediation.

In this Crystal Ball we describe the negative effects of the scheme of intensive agriculture of the green revolution technology. To recover the contaminated soils derived from intensive farming is necessary introduce new successful technologies to replace the use of chemical fertilizer and toxic pesticides by organic fertilizers and biological control agents. Our principal speculation is that in a short time authors in the field of PGPB and bioremediation will be expanding the knowledge on the development of different formulations containing super-bacteria or a mixture of super-bacteria able to provide beneficial effect for agriculture and bioremediation.
