In the 1800s English poet William Blake famously challenged his readers to “see a world in a grain of sand.” If only he had owned a modern microscope. Thanks to increasingly powerful optical tools, we now know that beneath the skin of every leaf, inside each speck of dirt, and within our own blo... Read More
Effect of founder cell density on the spatial pattern formation in colony biofilms.
The colony biofilms were obtained by following the protocol described in van Gestel et al (2014) ISME Journal (doi: 10.1038/ismej.2014.52). Briefly, GFP and mKATE2 labeled Bacillus subtilis strain were mixed in ... Read More
This cutely radish photo of the colony of Aspergillus niger was taken by a digital camera. Before that Aspergillus niger was grown on SDA (Saboraud Dextrose Agar) media for the research purpose of testing antifungal activity of Scallop Powder(SP). SP ,a natural source obtained from Bivalves, can... Read More

Did you know that the bright orange/pink colours on flamingos depended on the kind of food they ate?
Here, our white flamingo was created by 3 drops of different oils; olive oil, Tween 20 and Tween 80; in a little experiment to determine which would be the best oil for lipophilicity.
One d... Read More

For anyone interested in Antibiotic Awareness Week, a big part of the story is that patients (or their parents) demand antibacterials even for viral infections. And doctors often comply, just to get rid of them (the patients, that is). This high-resolution PDF can be printed out for waiting ro... Read More
Mannitol Salt Agar (MSA)
•Important Ingredients: Phenol red, mannitol (sugar), 7.5% NaCl
•Differential: between pathogenic S. aureus and S. epidermidis
•Selective: NaCl inhibits non-halophilic organisms. Organism that can grow are halophilic.
•Mannitol Fermentors: fermentation of acid cau... Read More
Rhizopus microsporus columella.
Species of the mucoralean genus Rhizopus are very relevant to society, in several respects. They are known as spoilage organisms,contaminating a variety of foodstuffs and agricultural
products during storage and transport. Because of off-odors, unwanted discolor... Read More
The spherical spores produced by the fungus Emericella nidulans are coated in a thin layer of the protein hydrophobin. Hydrophobin ensures that water rolls off the spores. Other fungi, such as mushrooms, also have a layer of hydrophobin on their caps. BASF researchers have succeeded in transferr... Read More

Fruiting body (Chasmothecium) of Phyllactinia sp., Erysiphales. Chasmothecium is a specific type of fruiting body amongst Ascomycota (others are Apothecium and Perithecium) with no natural opening. Appendages of Chasmothecium are currently used as distinguishing feature amongst Erysiphales gener... Read More
Cryptosporidium (Crypto) is a parasite that causes diarrheal disease. Crypto can live in the intestine of humans and animals and is passed in the stool of an infected person or animal. This parasite is very resistant to chlorine-based disinfectants and is protected by an outer shell that allows ... Read More
