Pengaruh perbedaan mikroorganisme dan suhu pada kandungan serat jerami padi fermentasi

Abstract

The aim of this research was to determine the NDF and ADF content of rice straw<br />fermented with several types of microorganism at different temperatures. Rice straw was<br />obtained from rice fields in Ishigaki District, Okinawa, Japan. The types of microbes used<br />were Lactobacillus fermentum, Bacillus subtilis, Bacillus coagulant Saccharomyces<br />cerevisiae, and Aspergillus niger. The mainplot was temperature (25, 35, 45°C) and the<br />subplot was microorganism. Each treatment has 3 replications. There were two groups for<br />controls, i.e. the control without molasses and the control with molasses. The rice straw<br />fermented within 3 weeks. The ADF content in all temperature treatments showed that S.<br />cerevisiae and A. niger treatments were higher (P<0.01) than that in other microorganism<br />treatments. Hemicellulose content in S. cerevisiae and A. niger were tend to lower (P<0.01)<br />compare to others microorganism treatments in all temperature treatments. The lowest<br />hemicelluloses content of fermented rice straw are showed by S. cerevisiae and A. niger at<br />45°C. These finding suggested that the ADF content were high in S. cerevisiae and A. niger<br />treatments, but showed decrease in hemicellulose and increase in cellulose and lignin.<br />Key words: rice straw, fermentation, ADF, NDF

Product Testing Strategy Implementation Results Biotechnology Feed: Paper

“…So that low quality feed, such as rice straw is able to provide enough energy in a relatively short time for maximum microbial mass production purposes. Each balance of urea ammonia rice straw and concentrates in the ration will directly affect the efficiency level of microbial protein synthesis (Yanti et al 2017). Formulation of rations is expected to synchronize energy needs with proteins for the growth and formation of microbial rumen proteins followed by increased concentrate content and increased pH and total VFA of rumen fluid.…”
