One hundred milliliter of Bold-basal salt medium with 8 boiled wheat grains in 250 ml conical flask was inoculated under aseptic conditions with 10ul of inoculum containing 40-50 ciliates.
Synthesis of Surfactant Modified Bentonite 2.0g Sodium bentonite (Na-BT) was added in 200 ml of distilled water and vigorously stirred in a conical flask for 60 minutes to achieve homogeneity.
Five conical flasks (250 ml) were supplemented with 5 g of five different raw materials (rice straw, molasses, wheat husk powder, potato peel powder, and milk straw) dissolved in 100 ml distilled water.
The acid dissolution method was adopted to determine the calcium carbonate content in the mixed medium as follows: the culture liquid in the conical flask was filtered with filter paper after incubating in a constant-temperature shaking incubator for a period of time, and then put the filtered paper containing residues and the conical flask into a beaker at 70[degrees]C for 24 hours.
The strain was cultured in 25 ml of medium in 250 ml conical flasks maintained at 30[degrees]C and 160 rpm for 72 h.
0.02g adsorbent was added to 50 mL of conical flask containing 20 mL of CR solution containing 0.1 M NaCl solution.
The bacterial cultures (24 h old) from enrichment medium were inoculated in the above selected mineral salts medium in a 100 mL capacity conical flask, with 0.5 g oil seeds extracts in each conical flask as the sole carbon source for the medium.
Impact of incubation time for maximum production of antimicrobial peptide was optimized by 1 % culture of producer strain grown in conical flasks containing 50 ml BHI broth maintained at 37 C.
All the biodiesel blends were stored in different conical flasks and sealed with aluminium foil for further tests.
After being ground, sieved, and dried overnight at 60[degrees] C, 5g of PKC was transferred to 150 mL conical flasks. Distilled water was added to the PKC to obtain PKC : moisture ratios of 1: 0.2, 1: 0.4, 1: 0.6,1: 0.8, and 1: 1 (w/v).
Taking two conical flasks, one without the addition of glucose, another with glucose, the concentration of 1,2,4-trichlorobenzene was tested every 1 d, 2d, 4d, and 8 d water sample.
Ground samples (50 g) were kept into different 500 mL conical flasks. Chemical solutions of different compositions of HCl, CaOH, citric acid, Iso-propanol, sodium hypochlorite, sodium bisulphate, acetone and ethanol were added into different flasks.
