A short break for a household tip on cleaning white resin chairs. We've had most of our white resin chairs for more than a decade--I'd say 14 years at least. After all that time they're still in good structural shape and sturdy and except for the nasty black stains there'd be no reason to throw them away. We've got six that sit out in the weather 24/7/365.
Another common shape of bacteria is the coccus. Cocci are spherically shaped bacteria that organize in several distinct arrangements when in groups: diplococcus, tetrad, sarcina, and staphylococcus arrangements.
1 Cocci (or coccus for a single cell) are round cells, sometimes slightly flattened when they are adjacent to one another. 2  Bacilli (or bacillus for a single cell) are rod-shaped bacteria.  Spirilla (or spirillum for a single cell) are curved bacteria which can range from a gently curved shape to a corkscrew-like spiral.
