Published: March 9, 2023

Bioaugmentation is widely used in soil bioremediation, wastewater treatment, and air biofiltration. The addition of microbial biomass to contaminated areas can considerably improve their biodegradation performance. Nevertheless, analyses large data sets on the topic available literature do not provide a comprehensive view mechanisms responsible for inoculum-assisted stimulation. On one hand, there no universal mechanism bioaugmentation broad spectrum environmental conditions, contaminants, technology operation concepts. other further outcomes under laboratory conditions field will strengthen theoretical basis better prediction bioremediation processes certain conditions. This review focuses following aspects: (i) choosing source microorganisms isolation procedure; (ii) preparation inoculum, e.g., cultivation single strains or consortia, adaptation; (iii) application immobilised cells; (iv) schemes soil, water bodies, bioreactors, hydroponics; (v) succession biodiversity. Reviews recent scientific papers dating mostly from 2022-2023, as well our own long-term studies, are provided here.

The increase in the production of highly recalcitrant plastic materials, and their accumulation ecosystems, generates need to investigate new sustainable strategies reduce this type pollution. Based on recent works, use microbial consortia could contribute improving biodegradation performance. This work deals with selection characterization plastic-degrading using a sequential induced enrichment technique from artificially contaminated microcosms. microcosm consisted soil sample which LLDPE (linear low-density polyethylene) was buried. Consortia were obtained initial by culture medium LLDPE-type material (in film or powder format) as sole carbon source. Enrichment cultures incubated for 105 days monthly transfer fresh medium. abundance diversity total bacteria fungi monitored. Like LLDPE, lignin is very complex polymer, so its closely linked that some plastics. For reason, counting ligninolytic microorganisms different enrichments also performed. Additionally, consortium members isolated, molecularly identified enzymatically characterized. results revealed loss at each end process. selected selective form more effective compared form, resulting reduction microplastic weight between 2.5 5.5%.

Bioaugmentation and vermicompost facilitated the hydrocarbon bioremediation: scaling up from lab to field for petroleum-contaminated soils

Environmental Science and Pollution Research, Journal Year: 2024, Volume and Issue: unknown

Published: March 22, 2024

Abstract The biodegradation of total petroleum hydrocarbon (TPH) in soil is very challenging due to the complex recalcitrant nature hydrocarbon, hydrophobicity, indigenous microbial adaptation and competition, harsh environmental conditions. This work further confirmed that limited natural attenuation hydrocarbons (TPHs) (15% removal) necessitates efficient bioremediation strategies. Hence, a scaling-up experiment for testing optimizing use biopiles TPH polluted soils was conducted with three 500-kg pilots soil, respective treatments were implemented: including control (CT), bioaugmentation vermicompost treatment (BAVC), combined application BAVC along bioelectrochemical snorkels (BESBAVC), all maintained at 40% field capacity. study identified pilot scale level, successful can achieve 90.3% removal after 90 days. BAVC’s effectiveness stemmed from synergistic mechanisms. Introduced consortia capable degradation, while provided essential nutrients, enhanced aeration, and, potentially, acted as biosorbent. it be concluded significantly enhances compared attenuation. While snorkel (BES) also showed significant removal, did not differ statistically individual BAVC, under applied Further research needed optimize BES integration broader applicability. demonstrates scalable mechanistically sound approach soil.

Unveiling the capacity of bioaugmentation application, in comparison with biochar and rhamnolipid for TPHs degradation in aged hydrocarbons polluted soil

Environmental Research, Journal Year: 2024, Volume and Issue: 252, P. 118880 - 118880

Published: April 4, 2024

Persistent, aged hydrocarbons in soil hinder remediation, posing a significant environmental threat. While bioremediation offers an environmentally friendly and cost-effective approach, its efficacy for complex contaminants relies on enhancing pollutant bioavailability. This study explores the potential of immobilized bacterial consortia combined with biochar rhamnolipids to accelerate total petroleum hydrocarbon (TPH)-contaminated soil. Previous research indicates that biosurfactants can increase rates, while mixed offer sequential degradation higher mineralization. The present investigation aimed assess whether combining these strategies could further enhance aged, matrices. bioaugmentation (BA) consortium increased TPHs (over 20% compared natural attenuation - NA). However, co-application BA rhamnolipid did not show statistically prominent synergistic effect. application facilitated maintenance degrading soil, identify direct influence degradation. contaminated contributed adsorption. Rhamnolipid alone slightly biodegradation NA, treatment between 27.5-29.8%. These findings encourage exploration amendment, like rhamnolipid, remediating diverse matrices hydrocarbons.
