“…In the present study, to elucidate the relationship between the microbiome and organismal acid tolerance, the larvae of 11 Chironomus species collected from both acidic and neutral areas in Japan were reared under the same laboratory conditions at pH 7-8 and their microbiomes were compared using amplicon sequencing. Although microbiome diversity was previously shown to be lower in several types of insects reared under laboratory conditions than in those in natural environments (Martinson et al, 2017;Tinker and Ottesen, 2021;Janakiev et al, 2023), we detected a difference between the microorganisms of acid-tolerant and acid-sensitive Chironomus larvae reared under the same laboratory conditions.…”

“…For example, Chironomus transvaalensis larvae were found to tolerate toxic heavy metals through the microbiome ( Senderovich and Halpern, 2013 ; Laviad-Shitrit et al , 2021 ). Recent studies reported that microbiomes in the larvae of C. riparius and Chironomus sancticaroli contributed to microplastic degradation ( Palacio-Cortés et al , 2022 ; Janakiev et al , 2023 ). However, comparative analyses of microbiomes in the larvae of different Chironomus species and their acid tolerance are lacking.…”

To obtain a more detailed understanding of organismal acid tolerance, the larval microbiomes of 11 Chironomus species collected from acidic or neutral pH areas in Japan and reared at pH 7–8 under laboratory conditions were systematically compared using an amplicon sequencing analysis. Evenness values were lower for the larval microbiomes of acid-tolerant Chironomus cf. riparius , Chironomus fusciceps , and Chironomus sulfurosus than for eight acid-sensitive species based on an alpha diversity analysis. The lower evenness observed suggested a biased abundance of microorganisms, which was consistent with the identification of Chironomus species-specific microorganisms (such as Agromyces mediolanus and Comamonas odontotermitis related bacteria) with high abundance in acid-tolerant larvae. The abundance of specific microorganisms was also high in the microbiome of acid-tolerant larvae of Chironomus acerbiphilus reared at pH 4, but not in that of acid-sensitive larvae. Based on a PICRUSt2 analysis, genes involved in saccharide transport were less abundant in the microbiome of acid-tolerant larvae than in that of acid-sensitive larvae, indicating nutrient-poor acidic environments. Although these results were obtained from single datasets, acid-tolerant larvae appeared to establish Chironomus species-specific interactions with microorganisms independent of saccharides, in contrast to acid-sensitive larvae. The present study is the first step towards understanding organismal acid tolerance.

“…These species, when present as a part of rhizosphere microbiota, were found to promote plant performance in saline-alkali soil under plastic film mulching. Janakiev et al isolated and examined species related to this genus from bacteriobiota associated with the gut of Chironomus riparius larvae and discovered potential candidates for the formulation of eco-friendly approaches to break down organic pollutants and microplastics within freshwater ecosystems [52].

The exposure of microorganisms to conventional plastics is a relatively recent occurrence, affording limited time for evolutionary adaptation. As part of the EU-funded project BioICEP, this study delves into the plastic degradation potential of microorganisms isolated from sites with prolonged plastic pollution, such as plastic-polluted forests, biopolymer-contaminated soil, oil-contaminated soil, municipal landfill, but also a distinctive soil sample with plastic pieces buried three decades ago. Additionally, samples from Arthropoda species were investigated. In total, 150 strains were isolated and screened for the ability to use plastic-related substrates (Impranil dispersions, polyethylene terephthalate, terephthalic acid, and bis(2-hydroxyethyl) terephthalate). Twenty isolates selected based on their ability to grow on various substrates were identified as Streptomyces, Bacillus, Enterococcus, and Pseudomonas spp. Morphological features were recorded, and the 16S rRNA sequence was employed to construct a phylogenetic tree. Subsequent assessments unveiled that 5 out of the 20 strains displayed the capability to produce polyhydroxyalkanoates, utilizing pre-treated post-consumer PET samples. With Priestia sp. DG69 and Neobacillus sp. DG40 emerging as the most successful producers (4.14% and 3.34% of PHA, respectively), these strains are poised for further utilization in upcycling purposes, laying the foundation for the development of sustainable strategies for plastic waste management.
