AI Article Synopsis

  • A model was created to explore how temperature and initial substrate concentration affect ethanol concentration using the yeast Saccharomyces cerevisiae.
  • Regression analysis was conducted with existing data to build a predictive model for ethanol concentration.
  • The model indicated optimal conditions for higher ethanol production are found at temperatures of 28°C to 32°C and an initial substrate concentration near 200 g/L, where higher temperatures and concentrations beyond 200 g/L negatively impact ethanol levels.

Article Abstract

In this study, a model was developed to simulate the effect of temperature ( ) and initial substrate concentration ( ) on the ethanol concentration limit ( ) using the yeast Saccharomyces cerevisiae. To achieve this, regressions were performed using data provided by other authors for to establish a model dependent on and capable of predicting results with statistical significance. After constructing the model, a response surface was generated to determine the conditions where reaches higher values: temperatures between 28°C and 32°C and an initial substrate concentration around 200 g/L. Thus, the proposed model is consistent with the observations that increasing temperatures decrease the ethanol concentration obtained, and substrate concentrations above 200 g/L lead to a reduction in ethanol concentration even at low temperatures such as 28°C.

Purpose: Acanthamoeba species are eucaryotic protozoa found predominantly in soil and water. They cause ulceration and vision loss in the cornea (Acanthamoeba keratitis) and central nervous system (CNS) infection involving the lungs (granulomatous amoebic encephalitis). Antiparasitic drugs currently used in the treatment of infections caused by Acanthamoeba species are not effective at the desired level in some anatomical regions such as the eye and CNS.

In Colombia, there is a long tradition of using bijao () leaves to package or wrap various foods. However, scientific studies on are limited, and research to evaluate its toxicity and/or antibacterial activity has not yet been conducted. The objective of this research, therefore, was to evaluate the content of phytochemical compounds, levels of toxicity, and antibacterial activity of the extracts, fractions, and essential oil derived from leaves.

The global food system is plagued by legitimacy and stability issues due to climate and ecosystem disruptions, contributing to widespread malnutrition. A significant portion of the global population experiences undernourishment, overweight, and micronutrient deficiencies from unhealthy diets. Addressing these challenges necessitates regular consumption of essential nutrients from plant sources.
