Kopi Luwak luwak beans to exporters whose produce ends up in Europe and Asia. Intensive farming is also criticised by traditional farmers because the civets do not select what they eat, so the cherries which are fed to them in order to flavor the coffee are of poor quality compared to those beans collected from the wild. According to an officer from the TRAFFIC conservation programme, the trade in civets to make kopi luwak may constitute a significant threat to wild civet populations. Kopi luwak is one of the most expensive coffees in the world, selling for between US$100 and $500 per
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
