1、Oil cakes and their biotechnological applications – A review

Non-edible oil cakes such as castor cake, karanja cake, neem cake are used as organic nitrogenous fertilizers, due to their N P K content. Some of these oil cakes are found to increase the nitrogen uptake of the plant, as they retard the nitrification of soil.

2、Solid

Flaxseed oil cake is the solid remaining after pressing the flaxseeds to extract the oil. It is often used as a feed component due to its high nutritional value (1).

3、Valorization of Oil Cakes as a Soil Amendment for Wheat

Here, we hypothesized that the inoculation with laccase-producing bacteria could reduce the phenolic content of oil cake and allow its valorization as bio-fertilizer.

Research implications: The association of nutrients from organic and mineral sources has shown promise in supplying the nutrient phosphorus, minimizing the effects of weathered soils on nutrient...

5、Can oil cake be used as fertilizer?

If oil cake is used as fertilizer, it must be fully fermented and decomposed before use, because incompletely fermented oil cake will generate heat in the flower pot and burn the roots and seeds, and the microorganisms inside can only react with each other to produce fertilizer effects after fermentation.

Sustainable valorization of oilseed cake using solid

Oilseed cake, husks, and fruit or vegetable peels are some examples of agro-industrial waste that are abundant in beneficial compounds essential for human health. Solid-state fermentation (SSF) has been recognized as a promising technique to enhance the nutritional quality of the oilseed cake.

Oilcakes as a potential substrate for sustainable agriculture

Nutrient-dense fertilizer: Oilcakes are rich in NPK, all of which are essential plant nutrients. The use of oilcakes as a fertilizer can improve soil health and crop yield. Soil improvement: By adding organic matter to the soil, oilcakes can improve soil structure, and fertility.

Unlocking the Potential of Oil Cake as a Fertilizer: A Comprehensive

Oil cake is a slow-release fertilizer, meaning that it releases its nutrients gradually over a period of time. This slow release of nutrients helps promote healthy plant growth, reduces the risk of over-fertilization, and minimizes environmental pollution.

Evaluation of biotechnological processing through solid

Oilseed cakes (OC) are natural sources of lignocellulosic biomass, produced every year in large amounts. In addition to their main applications as animal feed, plant or soil fertilizer, and compost, they present enormous potential for being used in ...

Effect of Oil

Using oil-cake and amino acid fertilizer as organic materials, both soil characteristics such as bio-chemical properties and microbial community and pepper yield were tested for three years.

Oil cake fermentation is an agricultural waste treatment technology primarily used to process byproducts such as rapeseed meal and peanut meal from oil crops. During oil extraction, these crops generate large amounts of oil residues, known as "oil cake." Oil cake contains abundant nutrients, including oils, proteins, and cellulose. If discarded directly, it could pollute the environment. through fermentation technology, oil cake can be transformed into organic fertilizers or bioenergy, achieving circular resource utilization.

oil cake fermentation is not a type of phosphate fertilizer. Phosphate fertilizers are phosphorus-rich materials designed to increase soil phosphorus content and promote plant growth. They are typically derived from phosphate rock through processes like high-temperature smelting and crystallization. In contrast, oil cake fermentation relies on microbial decomposition to break down organic matter into simpler substances, such as carbon dioxide, water, and organic acids, for resource recovery.

The oil cake fermentation process involves the following stages:

1. Pretreatment: Crush, dry, and pulverize the oil cake to increase its surface area for microbial contact.
2. Inoculation: Introduce beneficial microbial cultures into the pretreated oil cake to initiate fermentation.
3. Fermentation: Under optimal temperature and humidity, microorganisms decompose organic matter, producing gases, heat, and metabolic byproducts. This stage takes several days to weeks.
4. Post-treatment: After fermentation, solid-liquid separation and drying yield solid organic fertilizers or liquid bioenergy.

Advantages of oil cake fermentation include:

1. Resource recycling: Converts oil cake into organic fertilizers or bioenergy, reducing environmental pollution.
2. Reduced chemical fertilizer use: Organic fertilizers derived from fermentation can replace part of synthetic fertilizers, lowering agricultural costs.
3. Improved soil fertility: Organic fertilizers enriched with nutrients enhance soil quality and plant growth.
4. Environmental friendliness: Compared to chemical fertilizers, organic options cause less pollution and support sustainable development.

Challenges and limitations of oil cake fermentation include:

1. Process control: Fermentation requires precise management of temperature, humidity, and timing.
2. Microbial selection: The efficiency of decomposition depends on choosing the right microbial strains.
3. Post-treatment complexity: Separating solid fertilizers and liquid bioenergy demands advanced technology and equipment.
4. Economic pressure: While beneficial, large-scale production and adoption remain cost-intensive.

oil cake fermentation is an effective waste treatment method that promotes resource recycling and reduces pollution. due to technical requirements, it is still under development and requires further research and promotion.
