Bacteria get a bad reputation \u2013 with all the breakouts<\/a>, infections<\/a> and deaths<\/a>.\u00a0<\/p>\n

Some bacteria are turning this assumption on its head.\u00a0<\/p>\n

Bioplastic from Rottnest\u00a0\u00a0<\/p>\n

Scientists at the Bioplastics Innovation Hub<\/a> recently discovered a type of bacteria<\/a> that could grow bioplastic, specifically polyhydroxyalkanoate (PHA)<\/a>.\u00a0<\/p>\n

Salinivibrio<\/a> bacteria belong to the large Vibrionaceae family of marine bacteria, which thrive in hypersaline environments such as the salt lakes of Wadjemup\/Rottnest Island.\u00a0<\/p>\n

Murdoch University researchers genetically decoded the bacteria to shed more light on its full capabilities. They examined each gene to pinpoint those that could produce PHA.<\/p>\n

PHA<\/a> is an exciting type of bioplastic because it can be made from waste materials, including leftover feedstock, and has a smaller carbon footprint than traditional plastic.<\/p>\n

As well as replacing regular plastic in food wraps, plastic bags and textiles<\/a>, it\u2019s used in the medical industry<\/a> for screws and plates used in grafts and implants.\u00a0<\/p>\n

While PHA is currently being manufactured<\/a>, it still has limitations. Murdoch\u2019s new research just might bring the bioplastic market to WA.\u00a0<\/p>\n

Plastic to Parkinson\u2019s medication<\/p>\n

While some bacteria can produce plastic, others can turn it into pharmaceuticals.\u00a0<\/p>\n

A research<\/a> team from the University of Edinburgh is producing a frontline medication for Parkinson\u2019s disease using genetically engineered E. coli<\/a>.\u00a0<\/p>\n

The process, called bio-upcycling<\/a>, has been used to create various other products<\/a> from plastic, but the team believes they are the first to use it to make medication for a neurological disease.\u00a0<\/p>\n

Levodopa<\/a> is often used when symptoms become too much to handle with other drugs.\u00a0<\/p>\n

While it\u2019s still early days, this discovery could harness the power of bacteria to create a more sustainable process of drug synthesis.\u00a0<\/p>\n

Martian bacteria\u00a0<\/p>\n

Researchers are also looking far beyond Earth \u2013 to how bacteria could help colonise Mars.\u00a0<\/p>\n

One of the barriers<\/a> facing the establishment of a Mars colony is the construction of infrastructure using available local materials. Carting bags of concrete into space isn\u2019t particularly feasible.\u00a0\u00a0<\/p>\n

A study<\/a> published in 2025 suggests Sporosarcina pasteurii and Chroococcidiopsis bacteria could be used to make concrete-like<\/a> materials from loose Martian soil.\u00a0<\/p>\n

S. pasteurii is known to produce calcium carbonate, a primary component of cement, and Chroococcidiopsis can survive in extreme environments. Chroococcidiopsis also produces oxygen, which makes this combination particularly useful.<\/p>\n

A mixture of the two could be perfect for building future Mars cities.\u00a0<\/p>\n

A lot of this research is quite theoretical and relies on humans actually wanting to colonise Mars, but it\u2019s still a creative way of using bacteria to solve construction issues.<\/p>\n

Crop resilience\u00a0<\/p>\n

Some bacteria are making a real difference here on Earth.\u00a0<\/p>\n

Australia\u2019s dry climate this year is thanks to El Ni\u00f1o<\/a>. As we head into summer, these drought<\/a> conditions caused by El Ni\u00f1o and exacerbated by climate change<\/a> will be even more prevalent.\u00a0<\/p>\n

Many plants are struggling in these increasingly extreme conditions, including agricultural crops.\u00a0<\/p>\n

Researchers at Western Sydney University are investigating bacteria that can make wheat plants more drought resistant<\/a>.\u00a0<\/p>\n

The study<\/a> found wheat plants naturally send out signals to attract friendly soil bacteria, Streptomyces and Leifsonia, when faced with drought.\u00a0<\/p>\n

When the researchers reintroduced these bacteria into the soil of drought-affected crops, the crops grew taller and healthier and produced more grain. Bacteria could be used to get our crops through future droughts and produce better-quality and higher-volume crop yields, feeding more people.\u00a0<\/p>\n

While bacteria can be the source of death, disease and disaster, they also prove themselves as important tools for future innovation, tackling some of our most pressing global issues in healthcare, agriculture and space exploration.\u00a0 <\/p>\n","protected":false},"excerpt":{"rendered":"Bacteria get a bad reputation \u2013 with all the breakouts, infections and deaths.\u00a0 Some bacteria are turning this…\n","protected":false},"author":2,"featured_media":935884,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[502626,64,63,502644,502633,502641,502634,245776,502630,502624,502642,483040,60841,502627,4335,502631,68,502629,429309,34545,17964,502632,502639,392219,323521,391643,502645,24721,104413,10610,502643,3153,28911,502640,176534,502623,128,502635,327,502628,502638,256745,17891,502637,502636,34551,263516,176531,122675,502625],"class_list":["post-935883","post","type-post","status-publish","format-standard","has-post-thumbnail","category-science","tag-agricultural-biotechnology","tag-au","tag-australia","tag-australian-science-research","tag-bacteria-innovations","tag-bacteria-on-mars","tag-bacteria-research","tag-beneficial-bacteria","tag-bio-upcycling","tag-biocement","tag-biodegradable-plastics","tag-biomineralisation","tag-bioplastics","tag-bioplastics-innovation-hub","tag-biotechnology","tag-chroococcidiopsis","tag-climate-change","tag-crop-resilience","tag-drought-resistant-crops","tag-e-coli","tag-environmental-sustainability","tag-genetically-engineered-bacteria","tag-leifsonia","tag-levodopa","tag-mars-colonisation","tag-martian-soil","tag-microbial-biotechnology","tag-microbiology","tag-murdoch-university","tag-parkinsons-disease","tag-pha-bioplastics","tag-plastic-pollution","tag-plastic-recycling","tag-polyhydroxyalkanoate","tag-rottnest-island","tag-salinivibrio-bacteria","tag-science","tag-soil-bacteria","tag-space-exploration","tag-sporosarcina-pasteurii","tag-streptomyces","tag-sustainable-agriculture","tag-sustainable-construction","tag-sustainable-pharmaceuticals","tag-sustainable-science","tag-synthetic-biology","tag-university-of-edinburgh","tag-wadjemup","tag-western-sydney-university","tag-wheat-farming"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/935883","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=935883"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/935883\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/935884"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=935883"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=935883"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=935883"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
