Fourier Transform Infrared Spectroscopy (FTIR) stands out as an effective and environmentally friendly tool for selecting microorganisms with biotechnological potential. This study utilizes FTIR to identify suitable fungal strains for the hydrolysis of microalgae biomass (Desmodesmus subspicatus and Chlorella sp) post-lipid extraction. Eleven fungal strains are selected, applying FTIR and multivariate analysis to choose filamentous fungi. The maximum cell density is 28.7 × 106 cells mL-1 for Chlorella sp. and 15.8 × 106 cells mL-1 for D. subspicatus, with total carbohydrates of 23.1% and 16.9%, respectively. Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) are useful for strain identification. Following the analysis, Penicillium G12 stands out for its ability to utilize D. subspicatus biomass, generating glucose and xylose (sugar yields of 9.4% and 6.6% respectively), and Trichoderma auricularis for Chlorella sp. (sugar yields of 12.9% and 9.6% respectively). FTIR proves successful in detecting fungal strains with biotechnological potential.","PeriodicalId":446097,"journal":{"name":"Revista Boaciencia.

The effectiveness of controlled composting (with rotation and irrigation) and natural composting was compared. Over a period of 120 days, tests were conducted on two composting beds using different materials (soy straw, wheat straw, tree prunings, and combinations thereof). Variables such as temperature, humidity, pH, carbon and nitrogen content, as well as reduction in mass and volume, were evaluated. The controlled treatments maintained appropriate humidity, exhibited a milder thermophilic phase, and achieved greater reduction in mass and volume. pH values remained neutral in all cases, and a decrease in the carbon/nitrogen ratio was observed, indicating the formation of mature compost. In summary, controlled composting proved to be more efficient in transforming organic matter during the 120-day study period, regardless of the types of waste used.","PeriodicalId":446097,"journal":{"name":"Revista Boaciencia.
