Biodegradation of plastic and rubber by Fungi - Coggle Diagram
Biodegradation of plastic and rubber by Fungi
Background
Solution
Fungi produce enzymes that are able to degrade complex materials
Microorganisms are able to break down synthetic polymers
Objective
Evaluate fungal strains capability
Measure biological activity during degradation
Problem
Slow degradation turning into microplastics
large amounts of synthetic plastics in terrestrial and marine ecosystems
Trash recycling methods
Methods
Fungi were grown with plastic as primary carbon source
measured:
O2 consumption
CO2 production
Growth rate
Structural changes in plastics
Collect fungal strains
Culture them with and without plastics
Analysis of data:
ANOVA to compare plastic tre
Dunn's test to investigate differences in O2 levels and CO2 amount in treatment groups
Results
Proved fungal strains metabolized plastics
labeled plastic isotope appeared in CO2 produced
Rate of polyethylene degradation
degradation slowed
Fungus used carbon as low efficiency energy source
Carbon wasn't incorporated as biomass
