Genetically engineered strains can produce significantly higher amounts of ammonia. Appropriate ammonia emissions can provide crops with the ammonia they need without excess amounts that can pollute lakes and oceans.[7]
A. vinelandii also produces significant amounts of alginate.[8]
Variable ploidy
A. vinelandii can contain up to 80 chromosome copies per cell.[9] However this is only seen in fast growing culture, whereas cultures grown in synthetic minimal media are not polyploid.[10]
