Table 1 Characteristics of degrader, helper, potentiator, and Potentiator Contribution Index (PCI) in DHP-Com

From: Potentiators empower synthetic microbiomes as silent guardians against co-contamination

 

Abundance

Significant difference in changes

Function

In this study

Degrader

Not necessarily high

Yes

Direct function, degrades pollutants

Strain C2

Helper

Not necessarily high

Yes

Indirect function helps degraders

Strains A1, P1, L3

Potentiator

High

No

Indirect function helps degraders and helpers

Strains B4, S4 (The abundance is usually among the top 30).

Potentiator Contribution Index (PCI)

PCI = \(\frac{{\mbox{Perfprmance}}\left({\mbox{DHP}}\right)-{\mbox{Perfprmance}}\left({\mbox{DH}}\right)}{{\mbox{Perfprmance}}\left({\mbox{DH}}\right)}\times 100\%\)

  1. \({\mbox{Perfprmance}}\left({\mbox{DHP}}\right)\) = Overall performance (e.g., pollutant degradation rate, community biomass) of the consortium containing Degrader (D), Helper (H), and Potentiator (P).
  2. Perfprmance (DH) Performance of the consortium with only Degrader (D) and Helper (H).
