This tenfold dilution was shaken vigorously by hand for one …Take the loaded counting chamber, put it under the microscope and check briefly with smallest magnification, if the distribution of algae cells is homogenous. Count the cells (see next section). Recommended volumes of liquid: Thoma (depth: 0.02mm): 2.2ul; Semen counting chamber (depth: 0.01mm): 1.8ul; Neubauer improved (depth: 0.1mm): 12ul
For more accuracy count the number of spores in all 100 squares (1 square containing 3 spores shown) and multiply by 2,500 to get the number of spores per bee. For example you counted 284 spores in 100 of the squares you …Aug 21, 2023 · Spores/m3 = average spore count per field/ 0.00785 mm2 x 908 mm2 (for 37 mm filter) or 375 mm2 (for 25 mm filter)/air volume in liters x 1000 L. If close-faced sampling is performed, cut a 2-mm-diameter area from the center of the filter for clearing and counting, since most of the particles and spores are concentrated in this area. The same method was used for viable spore counting. The same diluted samples were heated at 80 °C in a heating bath for 15 min and then chilled on ice for 5 min before being placed on TSA plates and incubated. Counting was reported as colony-forming units (CFU) per milliliter and expressed as total cell or spore counting per milliliter. ….
