The loss of hectares of forest areas has become a global issue that has worsened over recent years due to unsustainable human activities. In a context of limited availability of productive land, it is urgent to adopt efficient strategies to recover the affected natural areas. Actions based on a circular economy, such as the use of organic chemical matrices recovered from water waste treatment plant waste, have proven to be effective. In this regard, the addition of plant growth-promoting bacteria (PGPB), such as and , can contribute to the chemical treatment, favoring the recovery of soils, accelerating the recovery of vegetation cover, and inducing an increase in biodiversity. In this research, the effect of bio-fertigation under controlled laboratory conditions in is evaluated. After a thirty-six-week trial, the biometric and nutritional parameters of the plants were harvested and measured, and the diversity and composition of the metagenomes of their rhizospheres were evaluated. As well, the cenoantibiogram and the metabolic diversity were measured. The results showed that the use of these biofertilizers increased the variables related to plant production, quality of plant composition as an indirect means of their resilience, as well as an increase in rhizospheric microbial diversity and a reduction in their MIC resistance to the most widely used antibiotics. For all these reasons, the use of the biofertilizer result of the combination of WWTP waste, , and is postulated as an environmentally friendly strategy that can contribute to the recovery of potential oak forest areas.
由于不可持续的人类活动，近年来公顷数的森林面积损失已成为一个日益严重的全球问题。在生产性土地供应有限的背景下，迫切需要采取有效策略来恢复受影响的自然区域。基于循环经济的行动，例如使用从污水处理厂废物中回收的有机化学基质，已被证明是有效的。在这方面，添加植物促生细菌（PGPB），如[具体细菌名称1]和[具体细菌名称2]，可以有助于化学处理，有利于土壤恢复，加速植被覆盖的恢复，并促使生物多样性增加。在本研究中，评估了在[具体地点]的受控实验室条件下生物滴灌的效果。经过三十六周的试验后，收获并测量了植物的生物特征和营养参数，并评估了其根际宏基因组的多样性和组成。此外，还测量了群落抗生素谱和代谢多样性。结果表明，使用这些生物肥料增加了与植物产量相关的变量、作为其恢复力间接手段的植物组成质量，以及根际微生物多样性的增加和对最广泛使用抗生素的最小抑菌浓度抗性的降低。基于所有这些原因，将污水处理厂废物、[具体细菌名称1]和[具体细菌名称2]组合使用的生物肥料结果假定为一种环境友好型策略，有助于潜在橡树林地区的恢复。
