Arbuscular mycorrhizal fungi (AMF) play a crucial role in plant health due to their ability to improve tolerance to biotic and abiotic stresses. Our aim was to evaluate the effectiveness of a pool of native AMF from a harsh environment on plant performance and changes in soil attributes under different levels of drought. An experiment using maize was established, varying the soil water content to simulate severe drought (30% of the water-holding capacity [WHC]), moderate (50% of the WHC) and no drought (80% of the WHC, control treatment). Soil and plant attributes were measured (enzyme activity, microbial biomass, AMF root colonisation and plant biomass and nutrient uptake). There was a two-fold increase in plant biomass under moderate drought when compared to no drought treatment, but there was no difference in nutrient uptake. Under severe drought, there were the highest enzyme activities related to phosphorus (P) cycling and P microbial biomass, indicating higher P microbial immobilization. The increase in AMF root colonisation was observed in plants under moderate and no drought. Our findings demonstrated that the better use of the AMF inoculum varied according to drought levels, with better performance under moderate drought due to the increase in plant biomass. |

Bioactive edible films have been proposed from a calcium-crosslinked alginate matrix added with probiotic bacteria (Bacillus coagulans, as the bioactive component) and/or bacterial cellulose nanocrystal (BCNC)-stabilized palm olein Pickering emulsion (as a hydrophobizing component). The emulsion, however, instead of increasing the surface hydrophobicity and the barrier to water vapor, decreased both, due to discontinuities on the film structure and possibly the BCNC layer around the droplets minimizing the surface exposure of the hydrophobic phase (and its effects on film hydrophobicity). The probiotic bacteria, on the other hand, besides increasing the elastic modulus (which was ascribed to electrostatic interactions between teichoic acid and calcium), also enhanced both surface hydrophobicity and barrier to water vapor, probably due to the hydrophobicity of Bacillus spores. The probiotics exhibited high viability (> 8 log cfu.g− 1 , on a dry film basis) during film drying, storage, and digestion in a simulated gastrointestinal tract. |
