“…As found in the 2nd-month compost, Langarica-Fuentes, Zafar, Heyworth, Brown, Fox and Robson [ 37 ] similarly detected Diutina rugosa in the early stages of composting. Sun, et al [ 39 ] isolated and identified Diutina rugosa as a yeast strain with efficient phosphorus removal capabilities for wastewater treatment. The fungus was able to provide high phosphorus content as a fertilizer when yeast sludge was processed.…”

This work demonstrated the feasibility of an industrial-scale aerated static pile composting system for treating one of the common biowastes—soybean curd residue. The mixing ratios of the feedstock were optimized to achieve a carbon–nitrogen ratio and a moisture level in the ranges of 25–35 and 60–70%, respectively. This open-air composting system required 6–7 months to obtain a mature compost. Solvita and seed germination tests further confirmed the maturity of the compost, with 25% compost extract concentration yielding the best germination index in the absence of phytotoxicity. The bacterial and fungal compositions of the compost piles were further examined with metagenomic analysis. Thermoactinomyces spp., Oceanobacillus spp., and Kroppenstedtia spp. were among the unique bacteria found, and Diutina rugosa, Thermomyces dupontii, and Candida taylorii were among the unique fungi found in the compost piles, suggesting the presence of good microorganisms for degrading the organic biowastes.

“…Diutina was the dominant fungal genus in all the experimental samples, and its relative abundance in the CAS samples was much higher than that in the other three samples. Further analysis showed that the main species of Diutina is Diutina rugosa , which is a kind of yeast frequently studied in this genus and is mainly used to produce lipase ( de Freitas et al, 2021 ), being widely used in the chemical, food, energy, and environmental protection industries and other fields ( Ali et al, 2017 ; Sun et al, 2021 ). D. rugosa can also be occasionally found in the environment and the intestines of livestock and poultry.…”

Feed nutritional composition affects the intestinal microbiota and digestive enzyme activity of black soldier fly larvae

et al. 2023

IntroductionUsing black soldier fly larvae (BSFLs) to treat food waste is one of the most promising environmental protection technologies.MethodsWe used high-throughput sequencing to study the effects of different nutritional compositions on the intestinal microbiota and digestive enzymes of BSF.ResultsCompared with standard feed (CK), high-protein feed (CAS), high-fat feed (OIL) and high-starch feed (STA) had different effects on the BSF intestinal microbiota. CAS significantly reduced the bacterial and fungal diversity in the BSF intestinal tract. At the genus level, CAS, OIL and STA decreased the Enterococcus abundance compared with CK, CAS increased the Lysinibacillus abundance, and OIL increased the Klebsiella, Acinetobacter and Bacillus abundances. Diutina, Issatchenkia and Candida were the dominant fungal genera in the BSFL gut. The relative abundance of Diutina in the CAS group was the highest, and that of Issatchenkia and Candida in the OIL group increased, while STA decreased the abundance of Diutina and increased that of Issatchenkia. The digestive enzyme activities differed among the four groups. The α-amylase, pepsin and lipase activities in the CK group were the highest, and those in the CAS group were the lowest or the second lowest. Correlation analysis of environmental factors showed a significant correlation between the intestinal microbiota composition and digestive enzyme activity, especially α-amylase activity, which was highly correlated with bacteria and fungi with high relative abundances. Moreover, the mortality rate of the CAS group was the highest, and that of the OIL group was the lowest.DiscussionIn summary, different nutritional compositions significantly affected the community structure of bacteria and fungi in the BSFL intestinal tract, affected digestive enzyme activity, and ultimately affected larval mortality. The high oil diet gave the best results in terms of growth, survival and intestinal microbiota diversity, although the digestive enzymes activities were not the highest.

“…The constant reduction of phosphorus resources and the lack of control over the circulation of this element leads to unfavorable processes occurring in the environment. One of them is the disturbance of the balance of the production processes and the decomposition of organic substances in water bodies, leading to an increase in the productivity of these waters and their secondary pollution called eutrophication [ 2 , 8 , 9 ]. One of the main sources of phosphorus is municipal wastewater, providing 50–90% of the phosphorus compounds that are supplied to receivers along with discharged, treated wastewater, which makes it necessary to look for more and more effective technologies for the treatment of wastewater from phosphorus compounds [ 4 , 8 ].…”

Removal of Phosphorus with the Use of Marl and Travertine and Their Thermally Modified Forms—Factors Affecting the Sorption Capacity of Materials and the Kinetics of the Sorption Process

et al. 2023

View full text Add to dashboard Cite

The paper presents new reactive materials, namely marl and travertine, and their thermal modifications and the Polonite® material, analyzing their phosphorus removal from water and wastewater by sorption. Based on the experimental data, an analysis of the factors influencing the sorption capacity of the materials, such as the material dose, pH of the initial solution, process temperature, surface structure, and morphology, was performed. Adsorption isotherms and maximum sorption capacities were determined with the use of the Langmuir, Freundlich, Langmuir–Freundlich, Tóth, Radke–Praunitz, and Marczewski–Jaroniec models. The kinetics of the phosphorus sorption process of the tested materials were described using reversible and irreversible pseudo-first order, pseudo-second order, and mixed models. The natural materials were the most sensitive to changes in the process conditions, such as temperature and pH. The thermal treatment process stabilizes the marl and travertine towards materials with a more homogeneous surface in terms of energy and structure. The fitted models of the adsorption isotherms and kinetic models allowed for an indication of a possible phosphorus-binding mechanism, as well as the maximum amount of this element that can be retained on the materials’ surface under given conditions—raw marl (43.89 mg P/g), raw travertine (140.48 mg P/g), heated marl (80.44 mg P/g), heated travertine (282.34 mg P/g), and Polonite® (54.33 mg P/g).
