Descripción

General description

Gelatin is a versatile, high-quality hydrocolloid derived from porcine skin. It is a heterogeneous mixture of water-soluble proteins of high average molecular masses, present in collagen. noted for its ultrahigh gel strength, which is an important characteristic for various microbiological procedures where a firm gel is required, such as in culture media or other applications where the gel′s structural integrity is crucial.

Application

Gelatin is commonly used as a gelling agent in the preparation of solid and semi-solid culture media. It also aids in the study of aerobic and anaerobic microorganisms by providing a supportive structure for colony formation and development.

Components

La gelatina es una mezcla heterogénea de proteínas hidrosolubles de elevados pesos moleculares promedio, presentes en el colágeno. Las proteínas se extraen hirviendo en agua la piel, los tendones, los ligamentos, los huesos, etc.. La gelatina de tipo A procede de tejido curado con ácido. La B procede de tejido curado con cal.
