Microbes can accumulate a multiplicity of approaches and mechanisms that can help them in enduring and inhabiting pollutant rich environments. Such environment can expose microorganisms to harsh and unusual conditions were they slowly adapt themselves to maintain the structural integrity and normal functioning.

Difference in membrane property can be one of the factors but there are many other factors also at genetic and molecular level.

Ya it could be among a host of other factors including their genetic make up, the type of wastes and the environments in which they are located. Nice question Soomin Yang

The difference usually is caused by the different Metabolic pathways, actually, the implementer is enzyme.

Proper enzymes and the ability to extract electrons from a particular compund.

The microbes which are resistant to pollutants should contain plasmids in their cells among others. The plasmids play a key role in the production of enzymes capable to destroy pollutants. Some microorganisms do not possess plasmids in their cells.

I agree with Vit Mateju and a bit of their genetic makeup compared with the food they depend on Soomin Yang

Microbes can accumulate a multiplicity the mechanisms  that can help them in enduring and inhabiting pollutant rich environments. Such environment can expose microorganisms to harsh and plasmids  production of enzymes capable to destroy pollutants. 

Go back to microbial physiology, This is called metabolic pathways and microbial enzymes. These mechanisms are different from m microbe to microbe genus and species

See all microbes are not benificals some bacteria use as probiotics and some of the bacteria are harmful like that.

Based on bacterial nature

The main difference in enzymes which refer difference in genes.

Resistance to pollutants is determined by the ability of microbes to produce the enzymes involving in the metabolic pathways to utilize the pollutants. Such enzymes encoding genes are present in the genetic materials such as: DNA, plasmid of the resistant microbes. The difference in membrane property also plays a pivotal role to resist pollutants. Microbes possessing these properties can exhibit resistance to pollutants whereas those lacking cannot.
