Biphasic Medium having bacterial growth
Table of Contents
A biphasic medium is a culture system that combines both liquid (broth) and solid (agar) phases in the same container (usually a bottle or tube). It is designed to enhance microbial recovery by leveraging the advantages of both media types in one setup.
Surface Growth: A fluffy to cottony white colony is observed initially on the agar slope, later turning blue-green to grayish-green as conidia mature. Submerged Growth: The liquid portion appears turbid or with floating fungal balls/mycelial clumps. Sometimes a mat of fungal growth forms at the interface of liquid and solid phases. Pigmentation: No distinct diffusible pigment is produced in the liquid phase, but the agar slope demonstrates typical fumigatus colony color after sufficient incubation. It was later phenotypically confirmed with the LPCB tease mount microscopy of this culture.
