“…As an effective remediation tool, compound microbial agents have a wide range of enzymes and multiple degradation pathways to combat different contaminant intermediates, but the co-metabolism functions should be claried. 123 Secondly, it is vital to pay more attention on the metabolic process. Mass balance and 13 C-MFA are useful to better understand the ability of biodegradation and trace the fate of compounds, and control the whole process.…”

“…Regardless of the method, successful bioremediation requires using specialized organisms capable of degrading pollutants 10 . Natural attenuation has a poor remedial outcome in many cases, and there is a risk of residual contamination after a biostimulation operation 11 . For degrading recalcitrant hydrocarbons, employing bioaugmentation processes by adding fast-growing and easily culturable microorganisms with high stability, stress tolerance, and enduring high concentrations of pollutants could be beneficial 11 , 12 .…”

Biodegradation of high-molecular-weight petroleum hydrocarbons in saline conditions appears to be complicated and requires further investigation. This study used heavy crude oil to enrich petroleum-degrading bacteria from oil-contaminated saline soils. Strain HG 01, with 100% sequence similarity to Bacillussubtilis, grew at a wide range of salinities and degraded 55.5 and 77.2% of 500 mg/l pyrene and 500 mg/l tetracosane, respectively, at 5% w/v NaCl. Additionally, a mixed-culture of HG 01 with Pseudomonasputida and Pseudomonasaeruginosa, named TMC, increased the yield of pyrene, and tetracosane degradation by about 20%. Replacing minimal medium with treated seawater (C/N/P adjusted to 100/10/1) enabled TMC to degrade more than 99% of pyrene and tetracosane, but TMC had lesser degradation in untreated seawater than in minimal medium. Also, the degradation kinetics of pyrene and tetracosane were fitted to a first-order model. Compared to B.subtilis, TMC increased pyrene and tetracosane's removal rate constant (K1) from 0.063 and 0.110 per day to 0.123 and 0.246 per day. TMC also increased the maximum specific growth rate of B.subtilis, P.putida, and P.aeruginosa, respectively, 45% higher in pyrene, 24.5% in tetracosane, and 123.4% and 95.4% higher in pyrene and tetracosane.

“…Agri-food wastes can be processed, recovered and used in different ways after recovery. Recovery techniques can be associated with a specific field or can be a multidisciplinary study of different fields (Nwankwegu et al, 2022). When the literature studies in the field are examined, it is seen that environmentally friendly techniques are predominantly preferred in order to obtain the component with high nutritive potential from the food waste material (Appolloni et al, 2022).…”

PurposeOne of the popular fields to replace linear economy approach with the sustainable circular approach is the valorization of agri-food waste and by-products by using green methods. Celery peel contains essential nutrients as much as celery root. This study aims to propose a novel framework for investigation of celery root peel waste, which has high nutritional value and is beneficial for healthy nutrition, valorization potential to re-formulate ayran (a traditional Turkish drink).Design/methodology/approachSustainable green extraction/distillation methods were applied to the celery root peel material to obtain water soluble extracts to be used in formulation of traditional Turkish drink “Ayran”.FindingsAs a result of the study, a new functional fermented drink derived from traditional drink ayran was obtained by using celery root peel extract. In addition to the positive characteristic properties of samples in terms of physical, chemical, microbiological and sensory parameters, it was observed that it increased the shelf life by at least 50% compared to the drink from which it was derived.Originality/valueSeveral studies focused the valorization of food waste materials; however, to the best of the author’s knowledge, no study has been taken an approach for using green methods to add additional properties to traditional foods by using celery root peel extracts. Therefore, the study is a remarkable contribution to the circular economy and is a role model for further studies.
