“…At a low enough concentration, phosphorus can then become a limiting nutrient for cell growth. According to mixed and pure culture studies, phosphate limitation has been shown to cause selection of microbial communities (Kein€ anen et al 2002;Samaddar et al 2019) and to induce changes in cell physiology, such as degradation of polyphosphate or exchange of phosphorus-free membrane lipids, by affecting their metabolism (Romano et al 2015).…”

Phosphate limitation has been suggested as a preventive method against biofilms. P-limited feed water was studied as a preventive strategy against biofouling in cooling towers (CTs). Three pilot-scale open recirculating CTs were operated in parallel for five weeks. RO permeate was fed to the CTs (1) without supplementation (reference), (2) with supplementation by biodegradable carbon (P-limited) and (3) with supplementation of all nutrients (non-P-limited). The P-limited water contained 10 mg PO 4 l À1. Investigating the CT-basins and coupons showed that P-limited water (1) did not prevent biofilm formation and (2) resulted in a higher volume of organic matter per unit of active biomass compared with the other CTs. Exposure to external conditions and cycle of concentration were likely factors that allowed a P concentration sufficient to cause extensive biofouling despite being the limiting compound. In conclusion, phosphate limitation in cooling water is not a suitable strategy for CT biofouling control.

“…Los géneros Geobacter, Massilia son representativos puesto se caracteriza por tener alta producción enzimática para la solubilización de suelos, así como Phylia como Verrucomicrobia, Bacteroidetes, Acidobacteria, Chloroflexi, y Cyanobacteria (Samaddar et al, 2019). En otro estudio, Alori, Glick, y Babalola (2017) consolidaron documentación donde demuestran que microrganismos como Burkholderia gladioli, Bacillus sp.…”

Los arreglos agroforestales son estrategias donde se realizan cultivos mixtos de especies para favorecer una producción agrícola en particular, precisamente se esta promocionando para optimizar la producción de cacao. La acción de microorganismos edáficos en estos sistemas no se tiene del todo descrita, por tanto, se establece como objetivo el consolidar información sobre la acción de los microrganismos en ciclos biogeoquímicos sobre cultivos agroforestales para favorecer la producción de cacao. Para esto, se realizó un revisión bibliográfica de los temas relacionados usando bases de datos académicas, identificando que desde 2001 se esta trabajando en producción de cacao con arreglos agroforestales, así como determinando que la diversidad de bacterias edáficas es importante en tanto que participa en la transformación y biodisponiblidad de N, P y C; además, en el biocontrol de metales pesados que pueden afectar el grano. Se identificaron mas de 10 géneros de microrganismos con alguna acción potencial sobre la biogeoquímica de los suelos. La implementación de consorcios microbianos se convierte en una estrategias para fortalecer la producción de cacao sin el uso de agroquímicos.

“…Increases in plant performance and/or yield after an inoculation with P-solubilizing bacteria have been shown for many agronomically important crop species, including corn [153], soybean [154], wheat [154,155], rapeseed [156], mung bean [157], and tomatoes [158]. While the periodic application of P fertilizer has adverse effects on the structure and function of phosphate-solubilizing bacterial communities, the opposite is true when little or no superphosphate is applied [159].…”

Harnessing Soil Microbes to Improve Plant Phosphate Efficiency in Cropping Systems

Phosphorus is an essential macronutrient required for plant growth and development. It is central to many biological processes, including nucleic acid synthesis, respiration, and enzymatic activity. However, the strong adsorption of phosphorus by minerals in the soil decreases its availability to plants, thus reducing the productivity of agricultural and forestry ecosystems. This has resulted in a complete dependence on non-renewable chemical fertilizers that are environmentally damaging. Alternative strategies must be identified and implemented to help crops acquire phosphorus more sustainably. In this review, we highlight recent advances in our understanding and utilization of soil microbes to both solubilize inorganic phosphate from insoluble forms and allocate it directly to crop plants. Specifically, we focus on arbuscular mycorrhizal fungi, ectomycorrhizal fungi, and phosphate-solubilizing bacteria. Each of these play a major role in natural and agroecosystems, and their use as bioinoculants is an increasing trend in agricultural practices.
