Product Name: Rhodopseudomonas palustris
Synonyms: Purple non-sulfur bacterium, R. palustris
Recommended Use: Wastewater treatment, soil and water bioremediation, biohydrogen production
Supplier: Enter name, address, and contact details of manufacturer or distributor
Emergency Phone: Enter relevant emergency contact number
CAS Number: Not assigned, as this refers to a live bacterial culture
Product Code: Internal labeling as per supplier
Classification: Non-pathogenic, not hazardous under normal use conditions
Physical Hazards: None identified
Health Hazards: Low risk to healthy adults, immune-compromised individuals may experience irritative symptoms due to bioaerosols
Chronic Exposure: No evidence of chronic toxicity in occupational studies
Environmental Effects: Not expected to pose acute environmental danger, beneficial to certain ecosystems
Signal Word: None required
Pictograms: Not applicable
Precautionary Statements: Avoid direct inhalation of fine mist or dust in concentrated cultures; basic personal hygiene reduces risk
Cultural Identity: Rhodopseudomonas palustris, live suspended bacterial cells
Concentration: Usually delivered as a suspension in appropriate growth medium
Excipients: Nutrient broth, sodium chloride, trace minerals (specific composition may depend on manufacturing process)
Impurities: Expected to be free from genetically modified content and toxin-producing contaminants
Preservatives: None typically present
Physical State: Liquid or freeze-dried powder
Main Constituents: Bacterial biomass, metabolic byproducts and culture medium residues
Eye Contact: Rinse well with clean water for several minutes if splashed; seek medical attention if irritation persists
Skin Contact: Wash with soap and water; exfoliate with cloth if any visible contamination
Inhalation: Move to fresh air; mild irritation can be managed symptomatically; medical review required only if symptoms continue
Ingestion: Rinse mouth with water; non-toxic in studied exposures, but seek advice where pre-existing sensitivity or immune compromise exists
Notes for Doctor: Supportive treatment only; no specific antidote
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or CO2 for surrounding fire; no special measures specific to the bacteria
Special Hazards: Organic material in media may support combustion, but R. palustris is not flammable
Protective Equipment: Standard fire-fighting PPE (gloves, coats, eye protection, positive pressure respirator)
Combustion Byproducts: Carbon oxides, nitrogen oxides, low molecular weight organics
Personal Precautions: Wear gloves and eye protection in case of large spills
Environmental Precautions: Prevent uncontrolled releases into waterways; dilute solutions are not known to disrupt aquatic life
Cleanup Method: Absorb with inert material (sand, earth); collect and dispose of waste according to regulations
Hygiene Measures: Wash exposed skin and clean contaminated surfaces with detergent or alcohol for lab environments
Handling: Avoid generating aerosols or dusts; work in well-ventilated space if preparing large volumes
Storage Conditions: Store at 2–8°C for short-term stability (liquid culture), or as directed for freeze-dried material
Compatibility: Keep away from strong acids or bases that may damage cells or release unwanted byproducts
Packaging: Use sealed, leak-proof containers clearly labeled with organism name
Exposure Limits: No occupational exposure limits established
Engineering Controls: Standard laboratory ventilation sufficient; biosafety cabinet where aerosol generation is likely
Eye Protection: Safety glasses or goggles
Skin Protection: Laboratory coats, gloves made of nitrile or latex
Respiratory Protection: Dust mask or particulate respirator recommended for large scale processing
Hygiene Measures: Wash hands thoroughly before eating, drinking, or leaving work area
Appearance: Reddish-brown, turbid liquid or beige to pinkish solid (freeze-dried form)
Odor: Slight earthy, characteristic of microbial cultures
pH: 6.5–7.5 (liquid culture)
Boiling Point: Comparable to water for aqueous suspensions
Melting Point: Not applicable
Solubility: Suspension in water
Vapor Pressure: Not relevant
Density: ~1–1.1 g/mL (liquid suspension)
Stability: Stable if stored above freezing, deteriorates above 37°C or on extended exposure to sunlight
Other Data: Cultures deteriorate after repeated freeze-thaw cycles
Reactivity: Stable, no hazardous reactions in normal environmental or storage conditions
Chemical Stability: Stable during recommended storage; viability falls over time if not appropriately preserved
Incompatible Materials: Strong disinfectants, acids, bases, oxidizers
Hazardous Decomposition: Degrades into non-hazardous organic matter
Polymerization Hazard: Not applicable
Acute Toxicity: No evidence of acute toxicity through oral, dermal, or inhalation routes in humans
Skin Sensitization: Not reported, basic hygiene best practice
Eye Effects: Mild, reversible irritation only if directly splashed
Carcinogenicity: No IARC/NTP/OSHA classification
Mutagenicity: No evidence of genotoxicity
Other Data: Safe in agricultural and biotechnological applications based on existing literature
Toxicity to Aquatic Life: None expected; species used to improve soil, aquatic environments
Persistence and Degradability: Rapidly degrades into harmless byproducts
Bioaccumulative Potential: Not established, rapid die-off outside controlled environments
Mobility in Soil: High motility, non-invasive
Other Environmental Information: Used intentionally to support bioremediation, nitrogen fixation, and natural carbon cycling
Waste Disposal Method: Dispose of unused cultures as non-hazardous laboratory waste; autoclave or use EPA-registered disinfectant before landfill where required
Container Disposal: Decontaminate with dilute bleach or alcohol
Regulatory Considerations: Follow national/local regulations for disposal of biological cultures even if not classified hazardous
UN Number: Not regulated for transport
Proper Shipping Name: Non-hazardous biological sample
Transport Hazard Class: No restriction
Packing Group: Not required
Special Precautions: Insulate to prevent temperature extremes; ensure package integrity
Labeling: “Live microbial culture – non-pathogenic” or similar wording
Safety Regulations: Not subject to control under OSHA Hazard Communication Standard, European REACH Annex 1
Country-specific Rules: May fall under agricultural or ecological bio-product guidance in certain regions
Label Requirements: Identity, handling instructions, storage guidance
Other Regulatory Status: Approved for field trial and bioremediation in multiple jurisdictions under governmental oversight
