The concern on how food and livestock waste should be managed and recycled has greatly increased in the world. This research investigated the anaerobic decomposition (digestion) process for biogas production on dairy cattle manure (CM) and food waste (FW) using a bacteria as inoculum - Pseudomonas aeruginosa. CM and FW were co-digested with bacteria (P. aeruginosa) as the substrate. FW was allowed to decompose separately without inoculum for 30 days. Digesters (Bioreactor) were prepared in five places to monitor the maximum biogas production, generation rate of methane and number of days for the production of biogas. 1 to ratio 5ml and 10ml of FW were codigested with P. aeruginosa (bacteria) in 2 proportion and also Cow manure with 1 to ratio 1 and 0.5ml in 2 proportions [ 1:5ml; 1:10ml and 1:1; 1:5ml]. Batch process operation was used under mesophilic condition (35⁰C) for the digesters/bioreactor. Production of biogas was notices on the third and fourth day after commencement for the digesters with cattle manure, fourth to fifth day for the digester (bioreactor) with bacteria and third day for the digester with only FW. FW and CM generated highest cumulative biogas with volume of 88.5g/kg.

The Third

The study of biogas production was conducted to find effective fermentation which will enhance digester gas manufacturing system and reduce waste in military areas. Co-digester between food wastes with pig manure was studied. The experiment was divided into three proportions of food waste and manure based on dry matter mass. The first is 100:0 which contains 26 kg. of food waste. The second is 85:15 which was composed of 22 kg. of food per 4 kg. of pig manure. And the third is 70:30 which contains 18 kg. of food per 8 kg. of pig manure. Leavening agent for digester came from pig manure. The 21 day experiment was carried out to collect and analyze biogas samples. According to these results, the proportion 85:15 produced a large quantity of biogas which was 1,134 liters. Methane generation rate is increasing and hydrogen is also high as 32.26%. The heating reached the highest value at 1.491 MJ. or 3.189 times compared to the proportion 100:0 in the experimental temperature of 31-33 °C

The previous experiment was obtained that homemade activator is the best activator to produce biogas by using food waste consist of vegetable, fruit and rice waste.  The current research is carried out by adding chicken manure as a co-activator. Chicken manure content rich in nitrogen can be significantly enhance biogas production. This study is expected to increase the biogas production. There are two processes conducted at the laboratory scale, batch and semi-continuous process. The batch process aim to activate bacteria. The ratio set at food waste/chicken manure, 2 : 1 of digester #1, 3 : 1 of digester #2, 4 : 1 of digester #3 and digester control using food waste only. Stage two aims to produce biogas by adding food waste for 6 days periodically.  The ratio is set at food waste/water, 1 : 2. The highest biogas yielded is digester 2 with a cumulative volume biogas 120.77 liters consist of 71.01% CH4, 26% CO2, 2.9% O2 and 0.088% H2S. The potential of methane gas produced is 0.87 kWh and methane volume per TS and VS at around 18.72 L/kg and 34.68 L/kg, respectively.

The study aimed to determine the influence of addition of Sida hermaphrodita silage into cattle forage on efficiency of methane fermentation of cattle manure. Efficiency of methane fermentation connected with amount and composition of produced biogas was determined with respirometric tests. Methane fermentation was performed in mesophilic conditions with initial organic compounds loading of 5 g VS/(dm3∙d). The study was divided into two stages. In first stage, substrate in methane fermentation was only cattle manure. In second stage, substrate in methane fermentation was cattle manure and Sida silage. There were three series of experiments in each stage, due to cattle manure was obtained from cattle fed with forage differ in contribution of Sida silage (0 – series 1, 17% - series 2, 34% - series 3). In the stage 1, biogas production of 223±15 L/kg VS, 247±8.5 L/kg VS and 231±18 L/kg VS was noted in the series 1, 2, and 3, respectively. The addition of Sida silage to the cattle forage had no impact on biogas potential of cattle manure. In the stage 2, the same tendency was observed. No differences in biogas composition between series were also observed. Methane content in biogas was about 60%.

This study explored the effect of eight antimicrobials on the efficiency of biogas production in the anaerobic digestion (AD) process of cattle manure. The microbiome involved in AD, presence and number of genes mcrA, MSC and MST specific for Archaea, and antibiotic resistance genes (ARGs) concentration in digestate (D) were examined. Supplementation of antibiotics to substrate significantly lowered biogas production. Amoxicillin caused a 75% decrease in CH4 production in comparison with the control samples. Enrofloxacin, tetracycline, oxytetracycline, and chlortetracycline reduced the amount of biogas produced by 36, 39, 45 and 53%, respectively. High-throughput sequencing of 16S rRNA results revealed that bacteria dominated the Archaea microorganisms in all samples. Moreover, antibiotics led to a decrease in the abundance of the genes mcrA, MSC, MST, and induced an increase in the number of tetracyclines resistance genes. Antibiotics decreased the efficiency of the AD process and lowered the quantity of CH4 obtained, while stimulating an increase in the number of ARGs in D. This work reveals how antimicrobials affect the cattle manure AD process and changes in microbial biodiversity, number of functional genes and ARGs in the digestate due to drugs exposure. It also, provides useful, practical information about the AD process.
