For both fertilizers, plant growth began to decrease when 1.5 kg of
fertilizer was given.
D)
Rhizobia are bacteria that live on the roots of some plants, such as legumes like pea plants. Rhizobia convert an element in the
atmosphere into ammonia. Identify and explain the type of relationship this represents.
A)
It is parasitism because the bacteria absorbs food from the pea plant.
It is commensalism because the bacteria and pea plant don't harm each
B)
other.
It is competition because the rhizobia and pea plant both need the limited
amount of available nitrogen.
C)
It is mutualism because the bacteria receives carbon from the pea plant,
D)
Eliminate
while the plant uses the ammopia to make amíno acids.

- 1) The inactivation of Staphylococcus aureus was studied in pomegranate juice heated at 75°- 95°C. The slopes for the inactivation of this bacteria were calculated from the linear lines in semi-log graphical paper. The slope values were presented in Table 1. a) Determine the temperature change needed to inactivate this bacteria by 90%. b) Temperature change to inactivate Bacillus cereus in pomegranate juice by 90% at the same temperature range was 29°F. At 75°-95°C temperature range, which bacteria will be more affected by the temperature changes? Commend on your answer in one sentence Table 1- Slope values for the inactivation of Staphylococcus aureus in pomegranate juice heated at various temperature Temp.

Next in the pipeline is the production of calumpit juice, which is targeted for export to various countries. Alicyclobacillus acidoterrestris, a spoilage organism of concern in berry juices, has a D95oC = 1.0 minute in the new product. A.) If you inoculated 3.5x 104 cells to the juice, how long would it take to effect a 3-log reduction of the organism at 95oC? B.) How many cells will remain after four minutes of heating at the same temperature? C.) You found out that Geobacillus stearothermiphilus, another spore forming bacterium, can also spoil the calumpit juice. Thermal inactivation studies revealed a D95oC = 2.0 for G. stearothermophilus in the product. Which of the two spoilage bacteria is more heat resistant?
