Microbial Culture Media Solidification: Primary gelling agent for plates and slants to grow bacteria (e.g., Escherichia coli, Bacillus subtilis, Staphylococcus aureus) and fungi.

Colony Isolation and Enumeration: Enables streaking, spread-plating, and CFU counting from mixed or environmental samples.

Selective/Differential Media Preparation: Supports antibiotic selection, indicator dyes, and chromogenic substrates for strain screening.

Cloning and Transformation Plating: Used for recombinant selection and blue-white screening of Escherichia coli on LB-agar with antibiotics and IPTG/X-Gal.

Phage Plaque Assays: Employed as soft/top agar overlays for bacteriophage propagation and plaque visualization on bacterial lawns.

Bacterial Motility Assays: Low-percentage soft agar to assess swimming and swarming behavior of motile species.

Replica Plating: Transfers colonies between agar plates to screen phenotypes, nutrient requirements, or drug resistance.

Yeast and Fungal Cultivation: Gelling agent for media used with yeast and filamentous fungi in genetic and metabolic studies.

Plant Tissue Culture: Sterile gelling matrix for solid plant media in micropropagation and transformation workflows.

Strain Storage and Maintenance: Preparation of agar slants and stabs for short- to medium-term preservation of microbial stocks.
