Arabinose-Inducible Expression (PBAD/araC): Induces PBAD-controlled genes or systems (e.g., recombinases, Cas9) in Escherichia coli using 0.20% arabinose.

sacB Counter-Selection: 6% sucrose enables lethal selection against sacB-bearing cells for allelic exchange in Gram-negatives like Escherichia coli, Pseudomonas aeruginosa, and Vibrio cholerae.

Double-Crossover Mutant Isolation: Resolves single- to double-crossover events using sucrose-based counter-selection in strains such as Escherichia coli and Salmonella enterica.

Recombineering Workflows: Arabinose-driven induction of recombineering proteins supports chromosomal edits and cassette swaps in Escherichia coli.

CRISPR-Cas Selection: Arabinose-inducible CRISPR components enable targeted genome editing and counter-selection on plates.

Animal-Free Microbial Culturing: 1.69% animal-free soytone and 0.50% yeast extract support routine plating without animal-derived components.

Salt-Sensitive Applications: No NaCl formulation aids growth or selection of salt-sensitive strains, phenotypes, or plasmid systems.

Carbon Source Utilization Studies: Uses 0.20% arabinose and 6% sucrose to assess sugar-responsive regulation or catabolite effects in Escherichia coli.

Osmoprotective Recovery: High sucrose supports recovery of sensitive cells (e.g., post-electroporation or spheroplast stabilization) during plating.

Colony Screening and Titering: 1.50% agar provides firm plates for high-contrast colony morphology and selection across diverse Gram-negative bacteria.
