Recent progress in biodegradation of microplastics by Aspergillus sp. in aquatic environments

Colloids and Interface Science Communications, Год журнала: 2023, Номер 57, С. 100754 - 100754

Опубликована: Ноя. 1, 2023

The potential of Aspergillus sp. for plastic biodegradation is a promising approach environmentally friendly waste management. Various research studies have been conducted to optimize conditions that enhance the plastics and understand genetic basis species. By performing this investigation, we discussed role various species in decomposition polymers. Most grow within pH range 4 6. 37.5% showed grows optimally at 30 °C. Scanning electron microscopy (SEM) Fourier transform infrared (FTIR) tests were used 34.61% 32.69% different studies, respectively. It has observed fungi can biodegrade polymers more effectively size 20–100 μm. (34.21%) focused on 21 days. highest percentage (44%) low-density polyethylene (LDPE) by dominant sp., including A. niger, flavus, oryzae, play significant microplastics. Enzymes such as laccase, esterase, peroxidase, lipase, urease crucial roles degradation plastics. Laccase utilizes oxygen generate reactive species, breaking polymer chains. Esterase cleaves into fragments, while peroxidase generates radicals degradation. Lipases also contribute specific substrates. In general, it be said fungal successful degrading

Poly(lactic acid) and Its Blends for Packaging Application: A Review

Clean Technologies, Год журнала: 2023, Номер 5(4), С. 1304 - 1343

Опубликована: Ноя. 10, 2023

Biopolymers obtained from renewable resources are an interesting alternative to conventional polymers fossil resources, as they sustainable and environmentally friendly. Poly(lactic acid) (PLA) is a biodegradable aliphatic polyester produced 100% plant plays key role in the biopolymer market, experiencing ever-increasing use worldwide. Unfortunately, this has some usage limitations when compared with traditional polymers; therefore, blending it other biopolymers, such poly(butylene succinate) (PBS), succinate-co-butylene adipate) (PBSA), adipate-co-butylene terephthalate) (PBAT) different poly(hydroxyalkanoates) (PHA), considered method improve significantly, customize its properties extend range of applications. The following review highlights, first part, physico-chemical mechanical PLA comparison biopolymers listed above, highlighting various drawbacks PLA. second part deals recent developments, results, perspectives field PLA-based blends.

With a growing body of evidence that now links environmental pollution to adverse cardiovascular disease (CVD) outcomes, has emerged as an important risk factor for CVD. There is thus urgent need better understand the role in CVD, key pathophysiological mechanisms, and raise awareness among health care providers, scientific community, general population, regulatory authorities about CV impact strategies reduce it. This article part 2 2-part state-of-the-art review on topic CVD-herein we discuss major pollutants their effects highlighting CVD risk.

Plastic pretreatment: The key for efficient enzymatic and biodegradation processes

Polymer Degradation and Stability, Год журнала: 2024, Номер 222, С. 110698 - 110698

Опубликована: Фев. 13, 2024

In recent years, enzymatic degradation and biodegradation have attracted great interest in the recycling of plastic waste. Compared to other techniques, they numerous advantages such as mild reaction conditions both terms temperature pressure prevention use toxic solvents. The monomers formed during processes can result chemicals with high added value, which be purified reused at an industrial level. Unfortunately, factors, environmental related polymer's nature, influence biodegradation, making them very complex processes. An effective way increase consists subjecting material pretreatments various kinds, capable inducing modifications polymer it more susceptible action microorganisms or enzymes. This review has objective analyzing literature last 15 identify most efficient on base chemistry, also considering technical-economic aspects.
