Summary
Compost inoculation with a compound VT agent significantly improved temperature control and compost quality compared to single microbial treatments. Microbial inoculation enhances enzyme activity, promoting efficient decomposition of chicken manure.
Area of Science:
- Environmental Microbiology
- Soil Science
- Biotechnology
Context:
- Composting chicken manure is crucial for waste management and nutrient recycling.
- Microbial inoculation can potentially optimize composting efficiency and product quality.
- Understanding the impact of specific microbial agents on composting parameters is essential.
Purpose:
- To investigate the effects of single (Bacillus megaterium) and compound (VT agent) microbial inoculation on chicken manure composting.
- To analyze changes in temperature, oxygen, C/N ratio, water-soluble carbon (WSC), germination index (GI), and enzyme activities (cellulase, dehydrogenase).
- To compare the efficacy of different microbial inoculants in accelerating the composting process.
Summary:
- The compound VT agent demonstrated superior performance in initiating and maintaining high temperatures during composting compared to Bacillus megaterium.
- Microbial inoculation, particularly with the VT agent, led to lower C/N ratios, increased WSC, and higher GI, indicating improved compost maturity.
- Both inoculation types reduced oxygen concentration but increased cellulase and dehydrogenase activity, signifying enhanced organic matter decomposition.
Impact:
- Microbial inoculation, especially with compound agents, can significantly enhance the composting of chicken manure.
- Optimized composting through microbial agents leads to higher quality compost with improved nutrient availability and reduced pathogen risk.
- This research provides valuable insights for developing efficient microbial solutions for agricultural waste management and sustainable soil amendment.

Microbial communities in aquatic ecosystems play a key role in the natural breakdown of contaminants introduced through domestic and industrial effluents. Acting as biological catalysts, these microbes change and mineralize a wide range of organic and inorganic pollutants under different redox conditions.In oxygen-rich surface waters, aerobic heterotrophs lead organic matter breakdown, using oxygen as the terminal electron acceptor to efficiently oxidize substrates to carbon dioxide and water.
01:18Bioreactor Controls-II
In aerobic fermentations, oxygen is vital for microbial growth and metabolite production. Since air comprises only about 20% oxygen and the gas is poorly soluble in water—just 9 ppm at 20°C—supplying sufficient oxygen becomes a critical challenge, especially in high-demand processes like yeast growth or citric acid production. Even a fully saturated broth may offer only a few seconds of oxygen availability.To address this, sterile or scrubbed air is introduced into the fermentor via a sparger...
