The great metabolic activity that characterizes the microbiota allows it to maintain a symbiosis relationship with the human being, positively impacting the development of both. Some foods contribute to the microbiota, among these are fermented, vegetables, fruits and algae. The biota of different algae have been typified, however, there are no studies of the most consumed red seaweed in Peru, Chondracanthus chamissoi, kown as “yuyo”. In this study, the microbiota of C. chamissoi from Ancon and Paracas were typified and compared. Samples of the algae were collected from the sea, from the local market as well as a sample of the sea water for analysis by next-generation sequencing (NGS) of the 16S rRNA gene. As a result, we obtained a total of 153,323 sequences which were taxonomically assigned on 19 phylums, 41 classes, 90 orders, 193 families, 484 genera and 716 species using the Illumina Base Space platform. The most commonly found phylum was Proteobacteria followed by Bacteroidetes and Cyanobacteria. Twenty four species were found in common among the algae samples. In addition, a large number of species were found only in samples taken from the corresponding markets, indicating possible cross contamination. Between 55.27% -58.87% of the bacterial species found were not classified previously. A semi- quantitative analysis allowed to assign the relative representation of each bacterium in the algae from both locations, Ancon and Paracas. Many species that were found abundant have been previously studied, many of them involved in the food and / or health industry humans and animals. This is the case of Psycrobacter namhaensis; successfully used as a probiotic for Nile tilapia. Lewinella marina can use cellulose as a source of energy and, therefore, degrade it and can be useful in the beer industry. Pseudoalteromonas rubra has probiotic power by improving the culture of the larvae of the goldfish Seriola lalandi and also Loktanella sp. It contains omega 6, 7, 10 fatty acids. In summary, this study comprehensively describes for the first time the microbial richness associated with the yuyo, an important component of Peruvian cuisine.
