Abstract

This study was conducted to investigate the effectiveness of Lactobacillus sp and fructooligosaccaride (FOS) to reduce the volatile ammonia formation from chicken excreta and layer slurry. For each treatment-replication, 150 g of fecal material were collected from the poultry farm and placed in 500 ml beaker glass. The fecal sample was then treated with 2% Lactobacillus sp (2.6x106) cfu/g and 2% FOS and covered with plastic wraps. The volatile ammonia contents and pH were measured after one hour of standing (0 d) and repeated at 48 h intervals for 6 d. For the dropping slurry study, 300 g of each layer dropping slurry sample were used. Results indicated that 2% Lactobacillus sp or FOS supplementations in the feces and dropping slurry after 1 h up to 6 d reduced the ammonia odor formation, fecal pH, and moisture content. The Lactobacillus sp and FOS treated manure resulted in increasing  Lactobacillus sp count and reducing in E. coli, Salmonella, and Campylobacter in 6 days for both feces and layer dropping slurry. In addition, reducing moisture content was observed in treated manure. It is concluded that Lactobacillus sp and FOS reduced the volatile ammonia formation and pathogenic bacteria from chicken excreta and layer slurry.

Abstract

The experiment  was conducted in two phases.  The first experiment was to observe the effectivity  of six  culture of Bacillus and Lactobacillus bacteria for reducing fecal ammonia.  The second experiment was to evaluate the application of Bacillus and Lactobacillus bacteria as probiotic for reducing ammonia feses and litter in broiler chicken house and observe its effect on the performance. Six bacteria culture consisting of three species of Bacillus bacteria (Bacillus subtilis, Bacillus cereus and Bacillus thuringiensis) and three species of Lactobacillus bacteria (Lactobacillus acidophillus, Lactobacillus bulgaricus and Streptococcus thermophillus) were used in the first experiment and 200 Day Old Chicks CP 707 were used in application of probiotic at the second  experiment.  Probiotic treatment were administered by drinking water, sprayed on the litter, combination of drinking water and spraying, and without probiotic as the control. The result of the first experiment showed that the six bacterial cultures and their combination significantly (P<0, 05) reduced feses ammonia and pH. The result of the second experiment showed that the probiotic treatment was significantly (P<0, 05) reduced ammonia of fresh fecal and litter, but was not significantly improving the performance of the chickens. The conclusion of this experiment was that the combination of six bacterial cultures of Bacillus and  Lactobacillus as probiotic was effective to reduce ammonia pollution in poultry house

Abstract

Biofuel is an alternative energy to replace fossil fuels. The most popular form of biofuel today is bioethanol. Biofuels are considered as a suitable alternative to fossil fuels because they are more environmentally friendly. Production of bioethanol utilizing thermophilic microorganisms is more profitable because thermophilic microbes generally have the characteristics of being able to use a variety of substrates, low contamination, and resistance to high temperatures. The use of microbial consortia tends to give better results than the use of monoculture isolates to optimize bioethanol yields. The aim of this study was to determine the compatibility and ability of the best thermophilic bacterial triculture consortium from the Mudiak Sapan hot springs in producing biofuel. This research is a descriptive research, to test isolates of a consortium of thermophilic bacteria that produce bioethanol. The results of this study showed that consortium isolates tended to give better results than monoculture isolates. The best thermophilic bacterial triculture consortium from the Mudiak Sapan hot springs in producing biofuels namely MS 12, 17, 18 produced a bioethanol content of 0.863%.

Abstract

The xylanase enzyme has high commercial value in the industrial sector, including the food industry, animal feed, bleaching of pulp/pulp, lignocellulosic bioconversion as fuel, and in the food industry, namely the cheese, bread and meat industries, while in the non-food industry this can be used in detergents. Xylanase enzymes can be produced from microorganisms, one of which is thermophilic bacteria. Thermophilic bacteria are known to be able to produce thermostable enzymes and proteins that are heat resistant. Xylanase production in compatible bacterial consortia was higher than monoculture. The purpose of this study was to determine the bicultur consortium that has the potential to produce xylanase enzymes. This research is an experimental research. Enzyme activity testing used the Miller method with DNS (Dinitrosalycilic acid) reagent using a completely randomized design (CRD) with 3 repetitions. Data on the results of xylanase activity were analyzed by ANOVA test and DMRT follow-up test with a 5% significance level.The results of the thermophilic bacterial isolates in the consortium that have the potential to produce xylanase enzymes are MS18 & MSS15,  MSS15, MS16 and MS18 & MS16.

Abstract

The main conclusion contains what is the implication to other studies or to the future brought by the study. Xylanase is an enzyme that is widely used in industry because this enzyme can hydrolyze xylan (hemicellulose) into xylo-oligosaccharides and xylose. This enzyme can be produced by thermophilic bacteria. One of the benefits of xylanase is as an environmentally friendly fabric bleaching process (biobleaching). The use of xylanase enzymes can reduce the use of toxic chemicals such as chlorine by about 20-40%. The purpose of this study was to determine the effect of temperature and pH on xylanase production activity using rice straw xylan extract as a substrate and to see the potential of MS 18 thermophilic bacterial xylanase on fabric brightness. This research is a descriptive study with temperature and pH optimization treatment using 6 treatments and 3 replications, respectively. Enzyme activity was measured using a spectrophotometer with a wavelength of 540 nm. The data obtained are displayed in the form of tables and figures. The xylanase potential on the brightness level of the fabric was seen based on the results of the kappa number. The results of this study obtained the optimum temperature of xylanase activity at a temperature of 50℃ with the highest xylanase 3.792 U/mL. while at pH the optimum pH of xylanase activity was found at pH 7 with the highest xylanase production of 4.448 U/mL. The potential of xylanase on the brightness of the fabric based on the results of the kappa number is 2.04 lower than without using xylanase, which is 6.46.
