Kopi Luwak unusual process contributed to its rarity and subsequently, its high price. More recently, growing numbers of intensive civet "farms" have been established and operated across Southeast Asia, confining tens of thousands of animals to live in battery cages and be force-fed. Concerns were raised over the safety of civet coffee after evidence suggested that the SARS virus originated from palm civets. '"The conditions are awful, much like battery chickens", said Chris Shepherd, deputy regional director of the conservation NGO, TRAFFIC south-east Asia. "The civets are taken from the wild and have to endure horrific conditions. They fight to stay together
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
