Kopi Luwak tastes bad". A coffee professional cited in the SCAA article was able to compare the same beans with and without the kopi luwak process using a rigorous coffee cupping evaluation. He concluded: "it was apparent that Luwak coffee sold for the story, not superior quality...Using the SCAA cupping scale, the Luwak scored two points below the lowest of the other three coffees. It would appear that the Luwak processing diminishes good acidity and flavor and adds smoothness to the body, which is what many people seem to note as a positive to the coffee.” Tim Carman, food writer for the
Cellular waste product as well as by cells called anaerobes that selectively perform anaerobic respiration even in the presence of oxygen. In anaerobic respiration, weak oxidants like sulfate and nitrate serve as oxidants in the place of oxygen. Generally, in anaerobic respiration sugars are broken down into carbon dioxide and other waste products that are dictated by the oxidant the cell uses. Whereas in aerobic respiration the oxidant is always oxygen, in anaerobic respiration it varies. Each oxidant produces a different waste product, such as nitrite, succinate, sulfide, methane, and acetate. Anaerobic respiration is correspondingly less efficient than aerobic respiration. In the absence
