Life Cycle Plasticity of Colpoda aspera Fed With Petroleum Tolerant Gram‐Positive and Gram‐Negative Bacteria

Journal of Eukaryotic Microbiology, Volume 73, Issue 3, May/June 2026.
ABSTRACT Soil recovery after contamination relies on the surviving microbiota to reconstruct microbial food webs. The ciliate Colpoda aspera and Brevundimonas sp., Rhizobium sp1, Rhizobium sp2 (gram‐negative), Bacillus sp1, Bacillus sp2, and Microbacterium sp.(gram‐positive) remain active after pulses of light petroleum contamination.
