Metabolism of protein, carbohydrates and lipid during anaerobic fermentation of coffee pulp
An experiment was conducted (with coffee pulp and cowdung as substrates) in order to find out the biochemical and microbiological mechanisms involved in methane production. Different anaerobic bacteria viz., acid formers, proteolytic, lipolytic, cellulolytic and methanogenic bacteria were enumerated at three different stages of fermentation. The bacterial population was high in coffee pulp digester. The analysis of biochemical parameters like cellulose, hemicellulose, lignin, reducing sugars, lipid, protein and volatile fatty acids at Oth, 35th and 70th day of experiment revealed that maximun reduction of these materials was in coffee pulp digester, which supported maximun bacterial population and produced maximun gas. The enzyme assays of cellulase, protease, Beta-amylase, Beta-glucosidase and lipase were carried out at every 10th day of fermentation. The enzyme activity was higher in coffee pulp than compared to that in cowdung digester
