Organic Acids Production of Rice Straw Fermented With Several Types of Microorganism at Different Temperatures

Abstract

Tujuan penelitian ini adalah untuk mengetahui produksi asam organik dari fermentasi jerami padi dengan berbagai tipe mikroorganisme pada berbagai suhu. Rancangan penelitian yang digunakan adalah split-splot Rancangan Acak Lengkap. Petak utama adalah perlakuan suhu (25, 35, 45°C) dan anak petaknya adalah mikroorganisme (Kontrol, Kontrol+Molases, Lactobacillus fermentum, Bacillus subtilis, Bacillus coagulant, Saccharomyces cerevisiae, Aspergillus niger). Parameter yang diamati adalah produksi asam organik (asam laktat, asam asetat, asam propionat). Produksi asam laktat tertinggi pada perlakuan B. coagulans pada suhu 35°C (53,79 g/kg BK). Produksi asam asetat tertinggi pada perlakuan L. fermentum pada suhu 35°C (13,20 g/kg BK), sedangkan produksi asam propionat tertinggi pada perlakuan Kontrol pada suhu 35°C (0,37 g/kg BK).

Agricultural by-Products as Feed for Ruminants in Tropical Area: Nutritive Value and Mitigating Methane Emission

“…Combination microorganisms with actions that include chopping, reconstitution of moisture and pressing are also potential to improve the fermentation quality (Abdel-Aziz et al, 2015). As reported by Yanti et al (2012), fermenting rice straw with Lactobacillus fermentum resulted in better silage quality compared to bacillus and fungi (Aspergillus niger and Saccharomyces cerevisiae) (Figure 2). Acetic acid production in Lactobacillus fermentum treatment was highest among the treatments; lactic acid value was similar with control + molasses and Bacillus coagulant treatment.…”

Fermentation quality of ratoon rice fermented with fermented juice of epiphytic lactic acid bacteria from tropicalgrass

“…Alternative feeds other than straw have been widely studied, and even efforts to improve the quality of rice straw have also been studied [3] [4]. However, research on ratoon or singgang rice as animal feed has not been found.…”

Energy balance and methane emission prediction in Simmental Cross-breed Cattle Feeding different types of forages and concentrates

“…However, the growth area for kolonjono grass is getting narrower, so replacement feed ingredients are needed which are cheap and easy to obtain. One substitute feed ingredient that can be used by farmers is fermented rice straw [2]. The use of fermented rice straw is due to the increase in feed quality due to the involvement of microorganisms in degrading crude fiber, reducing lignin levels and anti-nutritional compounds, so that the digestibility value of feed from waste can increase [2] [3].…”

The rice straw used for feeding livestock in single form cannot meet the nutritional requirements of livestock.…”
