4000 - 6000 x g for a given period of time (depending on density, volume, etc.) is sufficient.
I'm not sure of the maximum rcf, but I've read of some people using 8000 x g. I'm not sure if the bacteria were viable afterwards.
I use a Beckman J6-B with a JS 4.2 rotor (6 x 1 liter) to harvest bacteria used in protein expression. The rotor's maximum rcf is 3300 x g (average) and a half hour spin clarifies my supernatant.
First post here and not sure if I can post links, but if this shows up it's a good introduction to centrifugation principles:

What is MSB agar?
MSB agar is selective for growth of mutans streptococci and contains per liter: 10.0 g tryptose, 10.0 g peptone, 1.0 g dextrose, 50.0 g sucrose, 4.0 g K2 HPO4, 0.075 g tryptan blue, 0.0008 g crystal violet, 15.0 g agar, 200 units bacitracin and 0.01 g potassium tellurite at a pH of 7.0.
What is phenylethanol agar made of?
Phenylethanol agar typically consists of peptone, yeast extract, sodium chloride, agar, and phenylethanol as a selective agent. It is used to inhibit the growth of Gram-negative bacteria and promote the growth of Gram-positive bacteria in culture media.
What is the bacteria exponential growth formula and how does it contribute to the rapid proliferation of bacterial populations?
The bacteria exponential growth formula is N N0 2(t/g), where N is the final population size, N0 is the initial population size, t is the time in hours, and g is the generation time in hours. This formula shows how bacteria can rapidly multiply by doubling in number with each generation. As a result, bacterial populations can quickly increase in size, leading to rapid proliferation.
How do you calculate bacterial growth in a laboratory setting?
Bacterial growth in a laboratory setting is typically calculated using the formula for exponential growth, which is Nt N0 x 2(t/g), where Nt is the final number of bacteria, N0 is the initial number of bacteria, t is the time in hours, and g is the generation time of the bacteria. By measuring the initial and final bacterial counts at specific time intervals, scientists can determine the rate of growth and make predictions about future growth patterns.
Function of crystal violet in gram stain?
Well if you stained with only crystal violet, then they would all be violet! If you do a Gram Stain the right way, you end up getting Gram positive being violet or purple and Gram Negative being red or pink.
When raising an object vertically what is the force required?
The force required to raise an object vertically is equal to its weight, which is determined by mass and gravity. This force can be calculated using the equation F = m * g, where F is the force, m is the mass of the object, and g is the acceleration due to gravity.
What is the force required to lift an object equal to?
The force required to lift an object is equal to the weight of the object, which is the mass of the object multiplied by the acceleration due to gravity (F = m * g). The force must overcome the gravitational force acting on the object in order to lift it.
Which law of motion creates the g force?
One way to think of the "g-force" is as a fictitious force - one that SEEMS to push you backwards, when you are being accelerated forward. Actually (from the point of view of an observer who is not accelerating with you), no backwards force is required - in fact, it is only by the fact that there is a forward force, NOT balanced by a backward force, that acceleration is possible in the first place.
How much force is needed to lift a 400 g mass is?
The force needed to lift a 400 g mass would be equal to the mass multiplied by the acceleration due to gravity. Using the formula F = m * g, where F is the force, m is the mass (in kg), and g is the acceleration due to gravity (approximately 9.81 m/s^2), the force required to lift the 400 g mass would be approximately 3.92 N.
What are the three g-forces?
The three types of g-forces are acceleration g-force, maneuvering g-force, and normal g-force. Acceleration g-force is felt during changes in speed or direction, maneuvering g-force is experienced during sharp turns or maneuvers, and normal g-force is the force of gravity experienced in everyday activities.
How much force required to lift the load of 2 kg?
The force required to lift a 2 kg load on Earth would be equal to its weight, which is given by the formula F = m * g, where m is the mass of the load (2 kg) and g is the acceleration due to gravity (9.81 m/s^2). Therefore, the force required would be F = 2 kg * 9.81 m/s^2 = 19.62 N.
Does the G in G-force stand for gravity?
Yes, the G in G-force stands for "gravity." G-force is a measurement of gravitational force experienced by an object in motion, relative to the gravitational force experienced at rest on Earth.
What is the c-g-s unit of force?
The cgs unit of force is the dyne. One dyne is equal to the force required to accelerate a one gram mass by one centimeter per second squared.
How do you play g-force in 3d?
play g force
Who plays the ferret in g-force?
there is no ferret in g-force
When was G Force created?
G Force was created in 1982.
What is G in centrifugal force 2000 G?
In the context of centrifugal force, "G" is a unit of measurement representing the force of gravity. When something experiences centrifugal force of 2000 G, it means the force applied to it is 2000 times that of Earth's gravitational force.
