“…Ortner et al (2015) confirmed that a significant part of trace elements in the anaerobic digester is not available for microbial uptake. The chemical speciation of metals changes during complex chemical or biochemical reactions such as the precipitation withS 2À , CO 3 2À , PO 4 3À and the formation of inorganic and organic complexes, which might make metals not directly bioavailable and raise the cost of metals additive.…”

“…The acid soluble, reducible, and oxidizable fractions are potential bioavailable (Ortner et al, 2015). The residual fraction fixed in the crystal lattice of the mineral components is the least bioavailable fraction of metals (Ortner et al, 2015). The changes of the speciation of Fe, Co, Mo, Ni in the reactor with 50% of optimal dosage implied that metals bioavailability greatly decreased during anaerobic digestion.…”

“…In general, the soluble fraction of metals is considered as the highest bioavailability, which is directly bioavailable for metals uptake by microorganisms (Gustavsson et al, 2013). The acid soluble, reducible, and oxidizable fractions are potential bioavailable (Ortner et al, 2015). The residual fraction fixed in the crystal lattice of the mineral components is the least bioavailable fraction of metals (Ortner et al, 2015).…”

“…These various effects of the TE depend on the environmental conditions, the background concentrations, bioavailability, and microbial uptake. Bioavailability of TE is often correlated with their speciation, which is the distribution of an element amongst different chemical species in a system (Worms et al, 2006;Ortner et al, 2015).…”

This paper discusses the potential to enhance the anaerobic digestion of food waste FW by supplementing trace elements (Fe, Co, Ni, Zn, Mn, Cu, Se, and Mo) individually as well as in cocktails. A series of batch experiments on the biomethane potential of synthetic food waste were performed with low (FW-A) and high (FW-B) trace element background concentrations prepared in, respectively, Delft (The Netherlands) and Tampa (Florida, USA). The most effective trace elements for FW-A were Fe with an increase of 39.2 (±0.6)% of biomethane production, followed by Se (34.1 ± 5.6% increase), Ni (26.4 ± 0.2% increase) and Co (23.8 ± 0.2% increase). For FW-B supplementing these trace elements did not result in enhancement of the biomethane production, except for Se. FW-B had a Se concentration of 1.3 (±0. 5) µ g/gTS, while it was below the detection limit for FW-A. Regardless of the FW source, Se resulted in 30-35% increase of biomethane production at a concentration range of 25-50 µg/L (0.32-0.63 µM). Volatile fatty acids analysis revealed that TE supplementation enhances their consumption, thus yielding a higher biomethane production. Moreover, additional experiments on sulfide inhibition showed the enhancing effects of trace elements on the anaerobic digestion of food waste were not related with sulfide toxicity, but with the enzymatic reactions and/or microbial biomass aggregation.

The influence of the bonding form distribution of Fe, Ni, Co and Mn and their potential bioavailability during the anaerobic degradation of maize straw was investigated. Two reactors were operated over 117 days at 37°C and different dosage strategies of mineral were studied in reactor (R2). Control reactor (R1) was metal‐limited over time. mineral supplementation (1 g L−1) once a week reported the highest methane yield (257 mL g−1 VS) with 30% of increment. Ni and Co predominated in their oxidizable bonding forms and Fe mainly existed as residual and oxidizable fractions. The potential bioavailability (Mn ˃˃ Co ≈ Ni ˃ Fe) of R2 was higher comparing to R1. Metal deprivation in R1 led to depletion of both sequential extraction fractions and total metal concentrations until the end of the process. This study confirmed that the dosage strategy of mineral has a stimulatory effect on methane production from crop maize waste.
