Antibacterial Peptides from Degraded Date Pits for Animal Feed

Solution Overview

Problem

The use of conventional antibiotics in animal feed to promote weight gain leads to antibiotic resistance and residual antibiotics in meat products, prompting the need for alternative solutions to treat and prevent bacterial infections in animals.

Innovation Solution

Development of antibacterial peptides derived from degraded date pits, specifically those with molecular masses less than 10 kDa and sequences such as SEQ ID NO:4 and SEQ ID NO:6, which can be administered to animals to prevent or treat bacterial infections, reducing the need for conventional antibiotics.

Solution Approach 2:

The patent employs short-lived peptide molecules that are naturally degraded in the environment and animal systems, preventing long-term accumulation and resistance development. These peptides are derived from renewable date pit waste material, making them economically viable and environmentally sustainable alternatives to persistent conventional antibiotics

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If conventional antibiotics are administered to animals to prevent bacterial infections, then bacterial growth is inhibited, but residual antibiotics remain in meat products intended for human consumption

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent utilizes peptides with specific molecular mass parameters (1-10 kDa) and defined amino acid sequences that are optimized for rapid metabolism and elimination from animal tissues, ensuring minimal to no residual presence in meat products while maintaining effective infection prevention

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts and isolates specific antibacterial peptide sequences (SEQ ID NO:4 and SEQ ID NO:6) from degraded date pits through solid state degradation processes, purifying the active components to achieve effective antibacterial activity without the contaminant residues associated with conventional antibiotic use

Inventive Principle:

AI summary

A method of treating or preventing a bacterial infection in an animal comprises administering to the animal an effective amount of an antibacterial peptide, the antibacterial peptide being derived from degraded date pits which are degraded by solid state degradation by a fungus, Trichoderma reesei. The antibacterial peptide has a molecular mass of less than 10 kDa and an amino acid sequence including (a) SEQ ID NO:4 or (b) SEQ ID NO:6. The bacterial infection is caused by a Gram-positive bacteria or a Gram-negative bacteria, for example, a Salmonella species, a Campylobacter species, a Shigella species, an Escherichia species, a Pseudomonas species, and a Staphylococcus species.
