An industrial biotech company called BiODX located in South Africa has developed a mild organic biocide called DECONT-X from citrus extracts. DECONT-X is non-corrosive, non-toxic, and has gained popularity for microbial decontamination. BiODX has conducted over 6 years of research and development in conjunction with CSIR to commercialize sustainable biocides like DECONT-X as alternatives to conventional hazardous chemicals. DECONT-X has been shown to be effective against various bacteria and fungi, while being stable across a wide pH range and compatible with other products. BiODX markets DECONT-X for use in industries like oil/petroleum, pulp/paper, and water

2. Who We Are?
An industrial biotech company situated in the CSIR Mining Innovation Centre,
with over 6 years already dedicated to R&D in conjunction with the Council for
Science and Industrial Research (CSIR) to develop sustainable biocides.
Based on the development of DECONT-X, a mild organic biocidal active ingredient,
BiODX products have gained popularity due to its non-corrosive properties and nontoxicity surrounding microbial decontamination.

3. The Technology
• BiODX’s research was based upon a principal which assumed that triggering
an action on sensory parameters of citrus would yield high dosages of
biological yield from the target gene.
• BiODX’s innovative processes use the natural enzyme reaction occurring from
the time of picking the fruit, where degradation of the antimicrobial component
starts as the fruit converts all resources (sugars, bioflavonoids, antimicrobials
etc.) in order to stay alive.
• Innovation is also seen in the formation of two active compounds that do not
exist in the raw fruit; these two compounds are formed by virtue of the digestion
process that converts citric acid and vitamins.
• Formulating preservative into the juice is a stoichiometric reaction. With
reference to the formation of vitamin C, a citrus oxidation-reduction system has
electron donating and electron accepting properties.

4. Active Citrus Extract
GC (gas chromatography) analysis identified active peak in citrus extract.
Bioflavonoids which is a main component of citrus has previously been reported
as having a growth inhibitory effect on bacteria such as colibacillus,
Staphylococcus aureus or methicillin-resistant Staphylococcus aureus.

5. Stabilised Citrus Extract
GC (gas chromatography) analysis of DECONT-X showing activity compounds and
newly formed sub compounds post digestion.
The reaction between the citrus extract and QAC is a stoichiometric reaction
causing an ion exchange between the two compounds allowing the big molecule
(citrus extract) to digest certain sugars and other elements into newly formed
compounds.

6. Regulatory Compliance
Originating in response to pollution laws in the USA, organic chemists use all the tools
and training of traditional chemistry to create non-hazardous chemicals and processes
that are "benign by design".

20. Bacterial Resistance
Bacteria learn to acquire immunity to conventional chemicals, which means:
• Stronger chemical concentrations
• Increased chemical costs
• Increased water / rinse costs
• Increased electricity / heating costs
• Increased process costs
• Increased labour / absenteeism costs
Bacteria do not identify DECONT-X as a poison and therefore do not imitate
development of resistance.
