Listeria monocytogenes colonies on ALOA (Agar Listeria Ottavani & Agosti) Medium.
ALOA Agar is a selective chromogenic medium for the detection of Listeria monocytogenes and Listeria spp. in food and environmental samples.
ALOA agar provides reliable and rapid results in 24 hrs at 37°C. The plate is easy to read with blue to blue-green colonies on an opaque background. L. monocytogenes produces a halo on the agar, while other Listeria spp. does not.

Algae may very well be grown on Mars to maintain human life

Sending a self-sustained mission to Mars is now a step nearer due to a brand new experiment by German researchers, who discovered that cyanobacteria can develop in Martian atmospheric circumstances. That is huge information and it means the algae may very well be farmed to create oxygen and gasoline...

This is Frontonia leucas (Ehrenberg, 1833) from the bottom sediment of a ditch. It can be found in plankton as well and prefers beta-mesosaprobic to alpha-mesosaprobic environments. Frontonia leucas feeds on bacteria, flagellates, diatoms, algae up to 50 μm in size, naked amoebas, testate amoebas (Arcella, Difflugia), ciliates (Coleps, Aspidisca) and even small metazoans (rotifers). The two most important characteristics for identification are the size of the oral apparatus compared to the overall size of the species and the single CV with long collecting channels.
In dirty environments (alpha-mesosaprobic) Frontonia leucas is common in sediments up to 5 cm depth.

Frontonia is a genus of free-living unicellular ciliate protists, belonging to the order Peniculida. As Peniculids, the Frontonia are closely related to members of the genus Paramecium. However, whereas Paramecia are mainly bacterivores, Frontonia are capable of ingesting large prey such as diatoms, filamentous algae, testate amoebas, and even, in some circumstances, members of their own species. In bacteria-rich saprobic conditions, Frontonia leucas can live as a facultative bacterivore.
Frontonia are widely dispersed, and members of the genus can be found in marine and freshwater environments on every continent.
