Negative * positive = negative Positive * positive = positive Negative * negative = positive
positive and a positive is a positive negative and a negative is a positive to answer your question: positive and a negative is a negative.
Negative * positive = negative Positive * positive = positive Negative * negative = positive
A positive
A positive.
Although mycoplasma lack a cell wall and therefore test gram negative, they are considered to be descendents of 'nonsporulating and endospore forming gram-positive bacteria' (Madigan et al., 2009), such as Lactobacilli, Bacilli and Streptococci, (Dandekar et al., 2002), which have lost their cell wall. Mycoplasmas are therfore classed as gram- positive bacteria. This is supported by ribosomal RNA and DNA analysis.

No, Mycobacterium phlei is not known to form capsules. Capsule formation is more commonly associated with certain pathogenic bacteria to help evade the host immune response. Mycobacterium phlei is a non-pathogenic soil bacteria and does not typically form capsules.
In bacteria, sporulation is the process of endospore formation which takes place inside Gram positive bacteria.
endospore
Mycobacterium phlei is a non-fastidious organism that is commonly found in soil and water. It is not commonly grown on Eosin Methylene Blue (EMB) agar, as EMB agar is more selective for gram-negative enteric bacteria. Instead, Mycobacterium phlei is typically cultured on media specifically designed for mycobacteria, such as Middlebrook agar or Lowenstein-Jensen agar.
I believe that you are referring to a bacterial endospore. Only a small number of bacteria can produce these (Gram-positive Firmicutes). Endospores are very tough and allow the bacteria that can produce them to survive high temperatures, pressures, drought, etc.
Pseudomonas aeruginosa is a Gram-negative bacterium and does not produce endospores. Endospore formation is a characteristic primarily seen in Gram-positive bacteria such as Bacillus and Clostridium species.
An Endospore.
Endospores are typically produced by Gram-positive bacteria. The endospore structure helps these bacteria survive harsh conditions by remaining dormant until more favorable conditions occur.
