Straw waste promotes microbial functional diversity and

2022/9/10/ · Straw is a promising candidate material for bioproducts; however, of the nearly 900 Mt. of straw generated annually in China (Ren et al., 2020), less than 1% of the total straw waste is used for industrial processing (Sarkar et al., 2012) and most is used as a bulking agent for manure fermentation (e.g., via composting).

Pig Manure - an overview | ScienceDirect Topics

The pig manure and rice-straw application to Cd-contaminated soil decreased Cd almost 40% ( Zhang et al., 2003 ). Similarly, a 4-year field experiment conducted by Xie et al. (2015) has proven that application of pig manure in a paddy field decreased Cd contents in grain, stem, and leaf by 37.5%, 44.0%, and 36.4%, respectively. Read more.

Effect of Straw Pretreatment on Cu and Zn Passivation and

2022/1/10/ · The experiment was designed with one set of mixed AF of pig manure and untreated wheat straw (CK), and three pretreatments of mixed AF of pig manure and wheat straw were designed: pretreatment with DW, 6% H 2 SO 4, and 6% NaOH. A glass jar with an effective volume of 2 L was used as a fermenter, in which the total weight of the

2024/1/2/ · Microbial community of bacterial species significantly correlated with NH 4 +-N and/or P for unprocessed manure before solid–liquid separation (UM), non-fermented

Using pig manure to promote fermentation of sugarcane

2014/1/2/ · In recent years, it is common to produce single cell protein through microbial fermentation with industrial wastes as raw materials, such as high-concentration fermentation wastewater, yellow

Pig manure treatment strategies for mitigating the spread of

2023/7/25/ · 5 kg of pig manure was mixed with Sitka spruce sawdust at the ratio of 4 (manure):1 (sawdust) (w/w) and placed in a bucket. Sawdust was obtained from the local hardware store.

Diversity and dynamics of the bacterial community involved in pig

2017/6/3/ · Overproduction of livestock manures with unpleasant odors causes significant environmental problems. The microbial fermentation bed (MFB) system is considered an effective approach to recycling utilization of agricultural byproducts and pig manure (PM). To gain a better understanding of bacterial communities present during the

Deciphering and predicting changes in antibiotic resistance

2024/4/30/ · Livestock manure is one of the most important pools of antibiotic resistance genes (ARGs) in the environment. Aerobic composting can effectively reduce the spread of antibiotic resistance risk in livestock manure. Understanding the effect of aerobic composting process parameters on manure-sourced ARGs is important to control their

Biohydrogen production via dark fermentation with pig manure

2020/5/7/ · These were fed with pig manure and glucose as co‐substrates. Hydraulic retention times were 22, 11, 6, and 3 d. Target pH was 5.5 within 5.3–5.7 and controlled by varying organic loading rate.

Comprehensive review on agricultural waste utilization and high

The content of undigested crude protein in animal manure is very high, the content of protein in air-dried chicken manure is 24–30%, in pig manure is 3.5–4.1%, and in cow manure is 1.7–2.3% . In the face of the severe contradiction between supply and demand of protein feed, livestock manure is a potential feed resource.

Using pig manure to promote fermentation of sugarcane

2014/3/1/ · Molasses alcohol wastewater (MAW) is difficult to be bio-treated and converted into biogas.In this study, MAW mixed with pig manure (PM) in different ratios was co-digested. Biogas production, chemical oxygen demand (COD) removal and the structure of microbial communities were monitored in the process. Our results showed that under

Occurrence and prevalence of antibiotic resistance genes in apple

2022/11/21/ · Fermented organic fertilizers made from pig manure contaminated with antibiotics are widely used in fruit tree production. However, their effects on the residual antibiotics and the spread of antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) in apple orchards are still largely unknown. In the present study, we

Co-digestion of cow manure and food waste for biogas

2023/1/1/ · When biogas externalities such as environmental, human, and animal health benefits are quantified and integrated into the overall economic benefits, biogas from AcoD of food waste and dairy manure is also a very appealing solution from a socio-economic viewpoint, such as the reduction of GHG emissions from dairy manure and food waste …
