2018/7/20/ · Fermentech Labs uses agriculture waste -- the crop residue or stubble which is burned by farmers to clear fields -- as the substrate (material on which the enzymes act) for the fermentation process. The bioreactor designed by Arora operates at a high substrate loading rate and under strict aseptic condition to produce industrial enzymes.
The goal is to determine the shortest retention time that is feasible for processing CELSS crop residues, thereby reducing bioreactor volume and weight requirements. Pushing the lower limits of bioreactor retention times will provide useful data for engineers who need to compare biological and physicochemical components. Bioreactor retention
Crop residue management is the practice of handling and utilizing the organic matter left behind after the harvest of crops. Crop residues consist of various plant parts, such as stems, leaves, roots, and other organic matter left in the field after the crop is harvested. Proper management of crop residues is important because it can
2020/10/23/ · In this study, the biomethane potential of five agricultural crop residues (ACRs) (rice straw, vegetable waste, maize straw, coffee husk and oil palm empty fruit bunches (OPEFB)) and five Fruit-Based Agro-Industrial Wastes (FBAIWs) (jackfruit straw, banana, orange, apple and pineapple peel waste) were evaluated. The carbon and
2024/6/1/ · Crop residues constitute cheap, renewable and abundant resources [81]. Production of crop residues is increasing as Cherubin et al. [82] estimated the global crop residues production from 2003 to 2013 and reported that about 3607.6 × 10 6 Mg of crop residues were produced from different crops (i.e cerals, barley, corn, millet, rice, wheat
2022/3/16/ · Derivation of volatile fatty acid from crop residues digestion using a rumen membrane bioreactor: A feasibility study Anh Q. Nguyen, Luong N. Nguyen, Md Abu Hasan Johir, Huu-Hao Ngo, Long D. Nghiem
2022/6/23/ · The factors affecting the metabolite production in bioreactors include: the gaseous atmosphere, oxygen supply and CO2 exchange, pH, minerals, carbohydrates, growth regulators, the liquid medium rheology, and cell density. The basic requirements of bioreactor system are as follows: Provision for cell-to-cell contact.
Denitrifying bioreactors can be effective for removing nitrate from agricultural tile drainage, however, questions about cold springtime performance persist. reductase gene (nosZ) was supported by crop residues than WC at 15.5°C, and CS and BS supported greater abundance than WC at 1.5°C. Production of N 2 O relative to nitrate removal ...
Field residues are materials left in an agricultural field or orchard after the crop has been harvested. These residues include stalks and stubble (stems), leaves and seed pods. Good management of field residues can increase efficiency of irrigation and control of erosion. The residue can be ploughed directly into the ground, or burned first.
2023/9/15/ · Crop residues are a precious commodity (Fig. 9.1).They have a value, although sometimes they are misguidedly considered “waste” or “trash.” Crop residues are multifunctional and are used for a number of purposes (Fig. 9.3), but their primary function is to conserve soil and water.The four main competing uses are soil and water
PII: S1369-703X(02)00132-8. animal feed sources, especially in developing countries. A major reason for this is the low protein content of the waste residues, which can be enriched utilising added
2017/4/1/ · Geometry, light source and mass transfer properties of bioreactor were reviewed. Photofermentative hydrogen production from crop residues, if feasible, can
2003/3/1/ · Abstract and Figures. This paper reviews bioreactor designs and their use for protein production under solid state fermentation (SSF) conditions using various agricultural by-products. The
2022/9/25/ · Approximately one kg of each sun-dried crop residue was oven-dried for 2 h at 105 °C in a hot air oven. After drying, the crop residues were crushed in a grinder and sieved with Indian Standard sieves to 2–3 mm particle size. Prepared crop residue samples were shorted and stored in a laboratory-controlled environment for biochar conversion.
2021/5/12/ · The amount of crop residue depends on the crop type, its growth, its method of tillage, and its method of harvesting. Cereal crops like paddy, Sorghum (jowar), and wheat produce significant residues. Crop residues are extremely helpful in adding organic matter to soil. They are generally used as feed, fodder, fiber, and construction …
