If you imagine any equipment projects would help, that's my focus and I would
help with development.

I'm thinking of tools like incubator, thermocycler,
pH meter, conductivity meter, pressured bioreactor, optical density, mass density -- all with an automation
mindset -- ethernet or plastic optical fiber connected, no galvanic connections:
battery/indoor photovoltaic powered and with design for automation with handler bots
to carry material from station to station. Radio is another interconnection method
to consider for the data depending on RF noise allowable in your lab. Ethernet is
a simpler starting point though. USB seems too limited to me, especially when ethernet is
everywhere already, and eases development of instrument apps -- they're just web apps then.

Cathal's suggestion seems like a natural to develop an anti-bacterial enzyme producer along
with some instrumentation to tell how much of the enzyme is produced and being effective
in a culture by measuring presence of the unwanted bacteria somehow. The vinegar bacteria presence
could be inferred by pH alone. What is a good indicator or maltolactic fermentor bacteria presence
in a culture broth?
