2012/3/27/ · Background and Aims Phosphorus (P) mineralisation from crop residues is usually predicted from total P or carbon: phosphorus (C: P) ratios. However, these measures have limited accuracy as they do not take into account the presence of different P species that may be mineralised at different rates. In this study P speciation was
Catch crops are removed from the field when mature, whereas nitrate-fixing intermediate crops can be left in place, or mixed into the soil, and used as green manure. Catch crops
2023/2/1/ · This study estimated the potential BHP from the dark fermentation of typical crop residues and its contribution to China's energy consumption and carbon emission reduction. In 2019, the available crop residue yield (including rice straw, wheat straw, maize straw, yam straw, and bean straw) was 9.2 × 10 8 t/a, and 4.7 × 10 8 t

2023/7/7/ · A literature review has been conducted on the. management, as well as the major microbial fermentation strategies that are used for converting residual crops into valuable products. Approximately
2017/4/1/ · A few studies were reported on pretreatment of crop residues for photo-fermentative hydrogen production (Mirza et al., 2013), particularly on pretreatment for dark and photo-fermentative hydrogen production from crop residues (Table 2).Water hyacinth, rich straw, barley straw, corn stalk, and corn cob have been studied for bio-hydrogen
2019/4/16/ · Dozens of bio-products are generated from sugars through fermentation processes using modified and unmodified bacteria, yeasts, or filamentous fungi, but only a few processes are under or close to commercialization. Among these bio-products are alcohols, organic acids, microbial oils and hydrocarbons, enzymes, biosurfactants, and
2021/1/1/ · The fresh animal manure is processed in a storage tank before processing in the homogenizing tank and is fitted with a mixer to make the waste flows more homogenous (Fig. 5.4). Mixed waste is transported uniformly through a rectifier to achieve a uniform 5–10 mm partition size and pumped to the required anaerobic fermentation
2023/3/15/ · Fermented antibiotic production is a secondary metabolic process, and fermented antibiotic manufacturers will produce a large number of bio-residues during the production process. One ton of raw antibiotics will produce approximately 8–10 tons of wet bacteria residue, and China produces nearly 10 million tons of antibiotic fermentation
2022/8/1/ · The treated EFR was used as organic fertilizer for soil applications from 2018 to 2020, while manure-derived fertilizer and chemical fertilizer were added for a comparison with the treated EFR (Fig S1).Compared with the soils that were given manure-derived fertilizer, the soils receiving treated EFR showed a much higher TN and
2015/10/24/ · Currently, the use of alternative renewable energies is broadly supported in many countries, some of which are seriously evaluating the possibility of using hydrogen as an alternative fuel in their power systems. Hydrogen production by biological processes, such as dark fermentation, is a very promising alternative. However, this process has
From year to year, mankind is struggling with an increasing climate crisis. Constant climate change is related to human activities. The global dependence on non-renewable fossil fuels to meet our current energy needs cannot be sustained longer in the face of depleting fuel reserves. Particular attention should be paid to biofuels produced from lignocellulosic
This kind of fermentation device is used to manage the pig manure, chicken manure, cow manure, sheep manure, Mushroom residue，Chinese medicine residue, Crop straw, the harmless process can be finished in 10 hours, it take less room maybe 10 -30 squre meter is enough and there is without pollution included in the process, in which the tempreture can
2024/2/24/ · Agricultural waste and agro-based industry by-products are low-cost feedstock commonly utilized for the production of biofuels (Fig. 8.1).It has been anticipated that nearly 4 billion tons of agro-residue is generated annually and 75% of which is contributed by cereal crops (Sarangi and Nayak 2021).Agro-waste includes the waste
