Consequently, the Southern Scientific University has established a laboratory that operates in the San Andres-Pisco district, whose purpose is to guarantee the sustainability of C. chamissoi, therefore, the objective of this study was to determine the technical and economic feasibility of the production of seedlings of this alga from a system of sporulation and spore settlement in the hatchery, through the use of tools such as cost structure, income estimation, cash flow, and calculation of NPV and IRR. The results obtained from this analysis in an expected scenario, using a time horizon of 10 years, show a positive NPV of S / 260,938.66 and an IRR of 33%, whose percentage indicates the high return on the investment made, concluding the convenience of executing the project for the generation of profitability, considering the implementation of strategies to meet market needs.","PeriodicalId":30853,"journal":{"name":"Arnaldoa","volume":"28 1","pages":"163-182"},"PeriodicalIF":0.0,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43014150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis of reducing sugars was carried out using the HPLC method and the soluble solids were determined by means of a table refractometer, while the sensory analysis was carried out considering the following attributes: color, humidity, intensity of aroma, aroma and aftertaste flavor. Regarding the sensory evaluation, honey samples from both species were accepted, although differences were identified. In San Roque de Cumbaza, M. eburnea honey was described as sweeter and in Yantalo, T. angustula honey was described as sweet and sour.

The disk-diffusion antibiogram test was used to assess antimicrobial activity. The obtained data were processed in the SPSS Statistics 22 program and were statistically analyzed according to the ANOVA test and the Duncan test. Results: There was a significant difference (p <0.001) in the results of the 3 concentrations of the hydroalcoholic extract of Physalis peruviana L. with the vancomycin control; due to these did not present an antimicrobial activity comparable to the control. As for the hydroalcoholic extract of Eucalyptus globulus Labill., according to Duncan’s test, its antimicrobial activity at a concentration of 100% (16.00 mm) was very similar to the effect produced by vancomycin (16.30 mm) against Staphylococcus aureus.
