Growth Inhibition Test of Freshwater Algae

Algae comprise a significant constituent of aquatic ecosystems, globally accounting for roughly 50% of the total photosynthesis. They serve as primary producers in both marine and freshwater environments, forming the backbone of the aquatic food chain by providing the foundation on which herbivores rely entirely for sustenance, and which consumers indirectly depend on via the nutritional cascade. However, their overgrowth can instigate hazardous ecological consequences, including the development of harmful algal blooms and eutrophication. Therefore, evaluating the probable impact of biocides, fungicides, industrial substances, and human and veterinary medicinal agents that may contaminate the aquatic milieu on algal growth and reproduction is of crucial importance. Algae are highly sensitive to xenobiotics, and standardized testing methods have been conventionally employed for many years. The freshwater algal growth inhibition test (FAGIT) is a recognized standard methodology for evaluating the toxicity of xenobiotics on algal populations by examining its ramifications on the growth of freshwater algae in aquatic environments. CD BioSciences provides a comprehensive service for conducting freshwater algae growth inhibition testing.

Our Services

We use the standard OECD guidelines for the FAGIT data interpretation, which include calculated EC₅₀ values and an assessment of statistical significance. We also use advanced statistical methods such as analysis of variance (ANOVA) and regression analysis to determine dose-response relationships and modeling.

• Sample Collection and Preparation
  We provide sample collection and preparation services to ensure the accuracy and reliability of the FAGIT. We follow standardized protocols and techniques to minimize variability and ensure accurate results.
• Exposure Design
  We specialize in the design and optimization of exposure protocols for the FAGIT. Our team of experts considers several parameters such as the test chemical concentration, exposure duration, and frequency to maximize the sensitivity of the assay and minimize animal use.
• Algal Culturing
  We provide culture services for algal species that are commonly used in the FAGIT. We maintain high-quality cultures in our laboratory conditions and provide standardized cultures for the FAGIT.
• Sample Analysis
  We provide comprehensive analysis services for the FAGIT. Our team of experts uses sophisticated techniques to analyze the data from the test, including measuring algal cell density and determining the growth rate.

Test Organism

We offer tests on different algae supplied by official breeders and grown in the laboratory under standardized conditions.

Species Sensitivity Destribution

To determine the species sensitivity distribution (SSD), other algae species such as chlorella vulgaris or tetraedron caudatum can be tested upon request.
