“…Alyssoides utriculata inoculated with single and mixed PGP inocula showed a remarkable increase in dry aboveground biomass (up to 4–5-fold over the control) in relation to more efficient phosphorous nutrition and the alleviation of metal stress, as already documented in recent studies regarding the beneficial effects of inoculated microbiota [ 16 , 21 , 32 , 44 , 45 , 46 ]. Such high biomass values support the effectiveness of PGPB P. fluorescens SERP1 to help plants cope with metal-rich soil stress and reach a significantly increased biomass compared with those reported in the literature.…”

“…Inoculation with PGPM and their consortia can help plants alleviate metal stress in metal-rich soils [ 16 , 21 , 32 ], counteracting physiological changes that cause lower biomass production and alterations in physiological responses, biochemical activities, and photosynthetic efficiency [ 5 , 6 , 7 , 8 , 43 ].…”

“…Phytoextraction is a cost-effective and sustainable technology with good public acceptance, although the process does require a significant amount of time to succeed. To improve metal hyperaccumulation, several assisted phytoremediation techniques can be exploited: (i) using chelating agents that increase the uptake and translocation of metals to the shoots [ 14 , 15 ]; (ii) the effective addition of exogenous phytohormones [ 16 , 17 , 18 , 19 , 20 ]; and (iii) inoculation with plant-growth-promoting microorganisms (PGPM), an emerging approach that employs plant growth promoting bacteria (PGPB) and plant-growth-promoting fungi (PGPF) to alleviate metal stress and support metal uptake [ 21 ]. However, chelating agents affect plants’ health via stunted growth and leaf chlorosis [ 14 ], reduced biomass [ 14 ], or increased risk of groundwater pollution via metal mobilization, as in the case of Ethylenediaminetetraacetic Acid (EDTA) [ 22 ].…”

The inoculation of plants with plant-growth-promoting microorganisms (PGPM) (i.e., bacterial and fungal strains) is an emerging approach that helps plants cope with abiotic and biotic stresses. However, knowledge regarding their synergic effects on plants growing in metal-rich soils is limited. Consequently, the aim of this study was to investigate the biomass, ecophysiology, and metal accumulation of the facultative Ni-hyperaccumulator Alyssoides utriculata (L.) Medik. inoculated with single or mixed plant-growth-promoting (PGP) bacterial strain Pseudomonas fluorescens Migula 1895 (SERP1) and PGP fungal strain Penicillium ochrochloron Biourge (SERP03 S) on native serpentine soil (n = 20 for each treatment). Photosynthetic efficiency (Fv/Fm) and performance indicators (PI) had the same trends with no significant differences among groups, with Fv/Fms > 1 and PI up to 12. However, the aboveground biomass increased 4–5-fold for single and mixed inoculated plants. The aboveground/belowground dry biomass ratio was higher for plants inoculated with fungi (30), mixed (21), and bacteria (17). The ICP-MS highlighted that single and mixed inocula were able to double the aboveground biomass’ P content. Mn metal accumulation significantly increased with both single and mixed PGP inocula, and Zn accumulation increased only with single PGP inocula, whereas Cu accumulation increased twofold only with mixed PGP inocula, but with a low content. Only Ni metal accumulation approached the hyperaccumulation level (Ni > 1000 mg/kg DW) with all treatments. This study demonstrated the ability of selected single and combined PGP strains to significantly increase plant biomass and plant tolerance of metals present in the substrate, resulting in a higher capacity for Ni accumulation in shoots.

Amaç: Bu çalışmada etkin mikroorganizmaların ve kompostun ayrı ve birlikte uygulanmasının ısıtmasız sera koşullarında biber (cv. Pusula F1) yetiştiriciliğinde verim, meyve kalitesi ve yaprak besin elementi içeriği üzerine etkilerinin belirlenmesi amaçlanmıştır. Materyal ve Yöntem: Araştırmada 5 konu denemeye alınmıştır: (1) Kontrol, (2) Ecorec kompost uygulaması (KMP), (3) Etkin Mikroorganizma (EM) uygulaması (dikimde ve 15 günde bir sürekli) (EM), (4) Dikimde EM uygulaması +kompost (EM+KMP) ve (5) EM uygulaması (15 günde bir sürekli) +kompost (15EM+KMP). Kontrol dahil olmak üzere tüm uygulamalara toprak analiz sonuçlarına göre mineral gübre uygulaması yapılmıştır. Araştırma Bulguları: Uygulamaların üst aksam ve kök yaş ağırlığına etkileri önemli bulunmuştur. Üst aksam yaş ağırlığı EM uygulamasında en yüksek olmuştur. Kompost uygulamasından en yüksek verim değerleri alınmıştır. Kompost uygulaması ile toplam ve pazarlanabilir verim değerleri sırasıyla %60.4 ve %61.4 artmıştır. Sonuç: KMP ve EM+KMP uygulamalarının verim ve bitki besin elementi alımına etkileri nedeniyle ön plana çıktığı ve yüksek verim ve toprak verimliliğinin sürdürülebilirliği açısından tavsiye edilebilecek uygulamalar olduğu sonucuna varılmıştır.
