en.Wedoany.com Reported - BioCambio Director Axel Paulsen published a column proposing biological solutions as an alternative to traditional chemical methods for controlling fungal infections caused by Saprolegnia in freshwater aquaculture. The company's Bioescudo 24/7 program employs a biotechnology called "Multifunctional Microbial Core (NMM)," which includes two microorganisms: Lactobacillus plantarum and Saccharomyces cerevisiae.

Paulsen noted that the global aquaculture industry suffers at least 10% in economic losses annually due to fungal infections. In addition to the common Saprolegnia parasitica, other invasive strains exist, such as Saprolegnia diclina, Saprolegnia ferax, and Saprolegnia australis. Traditional control methods rely on chemical treatments like formalin baths, bronopol, and high-concentration salt, but these pose operational risks, uneven distribution in ponds, potential damage to industrial wastewater treatment systems, and issues such as reduced production performance and biomass loss.

The Bioescudo 24/7 program aims to address these challenges. BioCambio serves as the official technical validation body for Brazil's Korin Company in the cold-water sector, with support from the Mokiti Okada Research Center (CPMO). The program's core involves the synergistic action of probiotics and yeast to achieve endogenous protection and stimulation, competitive exclusion, and bioremediation. Yeast acts as an immunomodulator, activating fish defenses and stimulating mucus production; probiotics and yeast colonize the fish's digestive system and mucosa, optimizing the physical protective barrier from within. Meanwhile, the microbial community colonizes tank walls, pond walls, and fish skin, competing with Saprolegnia for attachment sites, accelerating the degradation of organic matter, and reducing suspended solids in the water, thereby depriving the fungi of the nutrients and space needed for reproduction.
