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.
Candida albicans is a yeast and belongs to the fungal kingdom, so it does not have a gram classification like bacteria. Gram staining is a technique used to differentiate between gram-positive and gram-negative bacteria based on the composition of their cell walls.
Archaebacteria are neither gram positive nor gram negative because they do not have peptidoglycan in their cell walls like bacteria. Instead, they have unique cell wall structures that make them distinct from both gram positive and gram negative bacteria.
neither...it is a virus, and gram-staining, a microbiology tool, is not used to help identify or classify a virus
Hepatitis B virus is not a gram-negative or gram-positive bacterium because it is a virus, not a bacteria. Viruses do not have cell walls like bacteria, so they are not classified as gram-negative or gram-positive.
The shape is not specific it could be coccus(spiral), spirila, or bacillus(rod), depends on the bacteria. Gram positives are more complex and need different antibiotics to get rid of them, like tetracycline
Gram positive bacteria protect themselves using antibiotic resistance and their flagella to move. They do not have a membrane like the gram negative bacteria.

HIV is a virus and, therefore, is neither Gram positive nor Gram negative. The Gram stain is used to identify bacteria as either Gram negative or positive, depending upon the type of cell wall the bacteria has. The Gram stain cannot be used on viruses.
It is a pleomorphic Gram negative bacilli.
AnswerYou can use a "selective" medium that will inhibit the growth of Gram positive bacteria and only allow Gram negative bacteria to multiply. A medium which is commonly used for this is the McConkey agar which contains a crystal violet strain and allows only Gram negative cultures to grow.You can also eliminate Gram positive bacteria with antibiotics (e.g. ampicillin) provided that they are sensitive and not resistant.
gram staining differentiates between gram negative and gram positive bacteria by showing different colors. it shows blue or purple like color for gram positive bacteria and red color for gram negative bacteria. where as simple stain gives the same color to all the types of bacteria. hence it is difficult to differentiate between them.
Staphylococcus bacteria typically do not grow well on Eosin Methylene Blue (EMB) agar. EMB agar is selective for gram-negative bacteria, particularly Enterobacteriaceae, and contains dyes that inhibit the growth of gram-positive bacteria like Staphylococcus.
