How many bacteria can be found in 1 gram of sandy soil?
There can be billions to trillions of bacteria in 1 gram of sandy soil, depending on various factors such as soil composition, moisture content, and nutrient availability. Bacteria play a crucial role in soil health and ecosystem functioning.
How many species are in a gram of dirt?
There can be thousands to millions of species in a gram of dirt, depending on the soil type and location. Soil is a rich habitat for various microorganisms such as bacteria, fungi, protozoa, and nematodes. Each gram of soil can contain diverse communities of these species.
How plentiful are bacteria in water in soil?
Bacteria are typically more plentiful in soil than in water. However, both water and soil can contain vast populations of bacteria. In water, bacteria tend to be found in higher concentrations near the surface and in areas with organic matter accumulation, while in soil, they can be present in diverse ecosystems throughout.
Why does the gram seed need loam soil to grow?
Gram seeds require loam soil to grow because loam soil provides good drainage, aeration, and moisture retention, which are essential for the healthy growth of gram plants. The balanced mixture of sand, silt, and clay in loam soil ensures that the roots can easily penetrate the soil to access nutrients and water.

How many species of bacteria classified?
reasearchers have found 4000 different types of bacteria in 1 gram of soil. Their are about 5*1030 numbers of bacteria on this planet
What kingdom is gram positive bacteria?
Kingdom Gram-Positive Bacteria is a kingdom within the domain Bacteria.
What kingdom does spirillum belong to?
Spirillum belongs to the Kingdom Bacteria. It is a genus of Gram-negative, spiral-shaped bacteria that can be found in various environments, including water and soil.
Is azospirillum a gram positive bacteria?
Gram positive
Is klebsiella gram positive or negative?
i believe it is a gram bacteria which causes respiratory illness.
What is the difference between positive gram and negative gram?
The major difference between gram positive and the gram negative bacteria is the structure of their cell wall. The gram positive bacteria have two layers a plasma membrane and outer to it a peptidoglycan layer. But the gram negative bacteria have another layer other than the cell wall. While the gram negative bacteria has three layers. It has a plasma membrane that is called as the inner membrane, then a peptidoglycan layer and finally an outer membrane of phospholipids and lipopolysaccharides. There is space between the inner membrane and the peptidoglycan layer called as the periplasmic space. Peptidoclycan layer in the gram positive bacteria are much more thicker than that of the gram negative bacteria. The molecule teichoic acid is present in gram positive bacteria and the porin proteins are characteristically present in the gram negative bacteria. Gram positive bacteria usually produce exotoxins and the gram negative bacteria usually produces endotoxins. Gram positive bacteria gives Violet colour to the gram staining and the gram negative bacteria gives pink colour to the gram staining. In gram staining the bacteria is fixed on slides and then they are treated with Crystal Violet. After that they are treated with iodine and then they are decolourised. If the bacteria is gram negative then it shows Violet colour and if it is gram negative then it shows pink colour. Initially both strains show Violet colour after Crystal Violet treatment but on the treatment with iodine and decolourisation the gram negative bacteria loose colour and become pink. This is because in the gram positive bacteria the Violet crystals bind firmly to the peptidoglycan layer and the colour is not removed in later stages. In gram positive bacteria the colour does not penetrate much because of outer membrane and is lost much during decolourisation.
What is the structural difference in the cell walls of gram-negative bacteria that distinguishes them from gram-positive bacteria?
Gram-negative bacteria have a thinner peptidoglycan layer in their cell walls compared to gram-positive bacteria. Additionally, gram-negative bacteria have an outer membrane that contains lipopolysaccharides, which is absent in gram-positive bacteria.
Where does EDP pathway occur?
EDP pathway occurs in cytoplasmic matrix of soil microbes like pseudomonas , rhizobium , acetobacter , agrobacterium and gram negative bacteria. a gram positive bacteria , enterococcus faecalis also uses this pathway.
Which type of bacteria are present in curd either gram plus ve or gram -ve bacteria?
The bacteria present in curd are primarily Gram-positive bacteria. These include species like Lactobacillus acidophilus and Streptococcus thermophilus. Gram-negative bacteria are not typically found in curd as the fermentation process favors the growth of Gram-positive bacteria.
