Cosmic Compost: Official Launch

Just in time for Jupiter in Capricorn

Cosmic Compost is a celebration of the microscopic universe in the dust beneath our feet, acknowledging some of the most significant microbial players in the ecology of decomposition through the aesthetic of cosmic wonder.

This initial collection consists of 6 bacteria that have been chosen for their significance in the composting process and soil health, but also their relevance to human health and cultural interest. They have been organized based on the phase of the hot composting process where they are most prominent.

The designs are available as greeting cardspostersart printsnotebooksstickersthrow pillows, and mugs through RedBubble. Show your favorite earth loving, fermenting, microbe appreciating friend how much you appreciate them. Write them a love letter of micro-cosmic delight. Collect all 6 bacteria for a complete compost ecological successional experience!

Stage 1. Mesophilic Initiation: Lactobacillus + Leuconostoc

The initial mesophilic phase consists of a mix of decomposers and fermenters, as much of the fresh feedstock material is fermenting when it enters the pile. Bacteria like Lactobacillus and Leuconostoc are best known for their role in fermentation communities, and the production of foods like yogurt, kefir, and kombucha. Even though fermentation is an anaerobic process, these guys are aerotolerant, and can still do their thing in the presence of oxygen.

Stage 2. Thermophilic Activation: Bacillus + Actinobacteria (Streptosporangium)

The appropriate pile conditions increases microbial activity, raising the internal temperature of the pile until it shifts into the 2nd phase where it reaches peak thermophilic temperature and stays there for a few weeks. Bacillus species and Actinobacteria (phylum) are the dominant bacteria at this time. I chose Streptosporangium as the sample species for Actinobacteria, which is the name of a phylum.

Stage 3. Cooldown + Maturation: Pseudomonas + Enterobacter

As the original organic waste material breaks down and humus begins to form, the microbial activity slows down and the temperature begins to cool, entering the 3rd phase. At this time, the microbial ecology shifts its focus to lignin breakdown and humus formation. Ultimately, the compost is finished when the temperature has reached ambient and the microbial activity has calmed down and stabilized to regular rates. Pseudomonas and Enterobacter are often detected in mature compost.

I’ll be sharing an article about each bacteria over the next 6 weeks. Stay tuned for the first article on Lactobacillus!

Sneak Peek: Cosmic Compost

Stage 1. Mesophilic Initiation:
Lactobacillus + Leuconostoc

I’m launching Cosmic Compost, a design collection acknowledging the significant microbiota of decomposition ecology. I’m starting with a small series of 6 bacteria significant to compost microbial ecology, organized based on their roles during the 3 main phases of hot composting.

The designs are available as greeting cards, posters, art prints, notebooks, stickers, throw pillows, and mugs through RedBubble. Something fun for your favorite science or microbe loving friend.

This initial phase is a fermentation phase, with organisms like Lactobacillus and Leuconostoc leading the charge. Both Lactobacillus and Leuconostoc are found in fermentation communities, such as in the production of sauerkraut, cheese, kefir, kombucha, and even the anaerobic composting method bokashi.

During this initial phase of decomposition, it is the compounds that are easily degraded that are the first to be metabolized, such as simple sugars, starches, and lipids. After a few days, the frenzy of microbial metabolic activity releases heat and the temperature begins to increase.

I’ll be revealing the rest of the collection later next week, and will be sharing a weekly exploration of each organism. Consider this a sneak peek.
