PGPR-Treated Spent Mushroom Substrate Enhances Lignocellulose Degradation, Enzyme Activities, and Microbial Restructuring to Sustain Blueberry Rhizosphere Fertility
Spent mushroom substrate (SMS) is a major agricultural byproduct whose complex lignocellulosic matrix hinders direct reuse and poses environmental risks when stockpiled. This study evaluated whether pretreatment with plant growth-promoting rhizobacteria (PGPR) could enhance SMS as a soil amendment for blueberry cultiva...
