Abstract:

Research into polyethylene (PE) biodegradation has generated thousands of organism-level studies, yet no scalable, field-ready technology has emerged. By analysing 2931 bibliometric records alongside enzyme kinetics and ecotoxicology data, we identify three overlooked limitations. First, a reproducibility deficit, with fewer than 7% of studies reporting kinetic constants. Second, a taxonomic echo-chamber, with 65% of bacterial studies focusing on Pseudomonas despite fungi achieving consistently greater mass loss. Third, potential risks are underexplored, as oligomeric by-products are rarely quantified despite already reaching toxic thresholds in aquatic systems. To move beyond species-and-enzyme catalogs, we propose a five-layer 'PE-degradation cube' that quantitatively links abiotic priming, enzyme kinetics, trophic relay, reproducibility weight and by-product risk. The model pinpoints laccase-mediator systems and insect-gut consortia as the only dual-validated (bibliometrically hot and biologically efficient) pipelines ready for protein-engineering translation, offering a data-driven roadmap that previous reviews have not provided.

Other Algae

Other Algae

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...

Oxidation Numbers

Oxidation Numbers

In redox reactions, the transfer of electrons occurs between reacting species. Electron transfer is described by a hypothetical number called the oxidation number (or oxidation state). It represents the effective charge of an atom or element, which is assigned using a set of rules.

Acid Attack on Concrete

Acid Attack on Concrete

When acids come into contact with concrete, they initiate a chemical reaction that dissolves the hydrated cement paste. This process leads to softening and structural weakening of the concrete. This issue is commonly observed in environments such as chimneys, sewers, and industrial settings. The severity of the damage increases as the pH of the water interacting with the concrete drops below 6.5. In particular, a pH under 4.5 can cause significant concrete damage.
The rate at which hydrogen...

Overview of Algae

Overview of Algae

The kingdom Archaeplastida encompasses red and green algae, along with land plants. Unlike other protists with chloroplasts that arose through secondary endosymbiosis, only red and green algae originated from primary endosymbiotic events. This diverse group of eukaryotic organisms contains chlorophyll and performs oxygenic photosynthesis.Algae exist in various forms, from large brown kelp in coastal waters to green scum in puddles and stains on rocks or soil. Some species are responsible for...

Regulated Protein Degradation

Regulated Protein Degradation

It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Red Algae

Red Algae

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
