“…These wastes would be impossible to process directly with earthworms or tenebrionids. On the contrary, some studies show that BSFL compost presents high levels of unstabilized soluble organic matter, which requires double composting to transform it into humic acids [52]. We believe that this strategy could help to generalize the use of entomocompost in agriculture and gardening.…”

“…However, the compost generated with H. illucens has high contents of soluble organic matter and nitrogen. To stabilize this compost, double composting has been suggested to convert the soluble fraction to humic acids [52]. An added advantage of using algae as H. illucens feed is that BSFL are enriched with omega-3, generating an excellent feed for fish farming [53].…”

Since 2015, the invasive alga Rugulopteryx okamurae has explosively burst into the waters of the Strait of Gibraltar with serious repercussions on marine biodiversity, tourism and the fishing industry. Its elimination entails an enormous cost for the municipalities in the area and vermicomposting is proposed as a solution, but the anti-food secondary metabolites of the algae make it unfeasible. This work analyzed for the first time the bioremediation of this toxic algae using vermicomposting (Dendrobaena veneta and Eisenia fetida), blatticomposting (Eublaberus spp. “Ivory”), mealworms (Tenebrio molitor) and black soldier fly larvae (BSFL, Hermetia illucens). Both BSFL composting and blatticomposting are viable alternatives, as the toxics in the algae do not affect the long-term survival, growth or reproduction of these invertebrates. All other tested species do not resist consumption of R. okamurae. In parallel, a synthesis of current knowledge on marine macroalgae composting has been carried out. The results of this work will allow the use of insect farms in the upwelling areas that will eliminate algae, providing fertilizers and animal proteins that will be an economic aid to the municipalities in the affected coasts of southern Mediterranean Spain.

“…Mycoplasma has been known as a pathogen, but recently, it has also been shown that the abundance of Mycoplasma in the intestine was negatively correlated with the abundance of potentially pathogenic bacteria in trout and Atlantic salmon [62,63]. Besides, the Lysinibacillus facilitated the degradation of protein-like substances [64]. Species of Pseudoalteromonas are used as probiotics in aquaculture for their antibacterial, bacteriolytic, and algicidal activities [65][66][67][68].…”

A 12-week feeding trial was conducted to investigate the effect of the same fishmeal protein level replaced by black soldier fly larvae (Hermetia illucens) meal (BSFL) with different lipid contents on the growth performance and intestinal health of juvenile turbot (Scophthalmus maximus L.) (initial body weight 12.64 g). Three isonitrogenous and isolipidic diets were formulated: fish meal-based diet (FM), diets DF and FF, in which 14% fish meal protein of the FM diet was replaced by defatted and full-fat BSFL, respectively. There were no significant differences in growth performance, intestinal morphology, and mucosal barrier function between the DF and the FM group. However, diet FF markedly reduced the growth performance, intestinal perimeter ratio, and the gene expression of anti-inflammatory cytokine TGF-β ( P < 0.05 ). Compared to group FF, the communities of intestinal microbiota in group DF were more similar to group FM. Moreover, diet DF decreased the abundance of some potential pathogenic bacteria and enriched the potential probiotics, such as Bacillus. Diet FF obviously altered the composition of intestinal microbiota and increased the abundance of some potential pathogenic bacteria. These results suggested that the application of defatted BSFL showed more positive effects on fish growth and intestinal health than the full-fat BSFL, and the intestinal microbiota was closely involved in these effects.

“…In this context, the genera Lysinibacillus and Acinetobacter and the family Comamonadaceae increased their abundance relative to R4 with respect to the other reactor. Lysinibacillus is a key contributor in the degradation and formation of dissolved organic matter during composting [ 78 ] and some strains have As resistance and detoxification capacities [ 79 ]. Likewise, Acinetobacter and Comamonadaceae have been found in microalgal co-cultures and in PBRs treating wastewater with high biomass productivity, and their role has been attributed to the beneficial exchange of carbon dioxide and oxygen between algae and bacteria, as well as to the synthesis of vitamins for microalgal growth [ 41 , 80 , 81 ].…”

The treatment of pig manure is a major environmental issue, and photobioreactors containing consortia of microalgae and bacteria have proven to be a promising and sustainable treatment alternative. This work studies the effect of Cu, Zn and As, three toxic elements frequently present in piggery wastewater, on the performance and microbiome of photobioreactors. After dopage with Zn (100 mg/L), Cu (100 mg/L), and As (500 µg/L), the high biomass uptake of Zn (69–81%) and Cu (81–83%) decreased the carbon removal in the photobioreactors, inhibited the growth of Chlorella sp., and affected heterotrophic bacterial populations. The biomass As uptake result was low (19%) and actually promoted microalgae growth. The presence of Cu and As decreased nitrogen removal, reducing the abundance of denitrifying bacterial populations. The results showed that metal(loid)s significantly affected 24 bacterial genera and that they did not recover after exposure. Therefore, this study makes an important contribution on the impact of the presence of metal(loid)s in piggery wastewater that compromises the overall performance of PBRs, and so, the environmental and health impact of treated effluents.
