Your question is not clear. Do you mean do some Gram + bacilli produce resistant forms. If so, you are thinking of those bacteria that produce endospores. They form these when the environment becomes hash and unlivable for them. Most studies have been with Bacillus subtilitus and Clostridium. These four Clostridium have clinical interest because of the diseases they cause: C. botulinum, C. difficile, C. perfringens and C. tetani.
B. subtilitus is not really a pathogen but is now considered a normal gut bacteria.
Beta-lactamases are enzymes produced by bacteria. Gram-positive bacteria can produce beta-lactamases. This type of bacteria takes up the crystal violet stain in gram staining.
e.aerogenes is nitrate positive after reagents A and B--> A (sulfanilic acid ) and B (naphthylamine) to the incubated bacteria a red color was produced which indicates a that my bacteria does reduce Nitrate to nitrite.
Gramicidin S or Gramicidin Soviet is an antibiotic effective against some Gram positive and Gram negative bacteria as well as some fungi. It is a derivative of gramicidin, produced by the Gram positive bacterium Bacillus brevis. I found the answer from the website of BOC Sciences (bocsci.com)
its obvious!! methyl red test tells us if the bacteria is using mixed acid fermentation process. if it is following it will show +ve. vp test is used to detect whether acetotin is produced or not.if bacteria is using mixed acid fermentation process acetotin will not be produced. so our bacteria can be either mr +ve or vp -ve. or it can be both negative....it cant be both +ve for further doubts ping me at sandeepdsensation@gmail.com
The lactic acid is generally produced by members of the genus lactobacillus. These bacteria are generally harmless to humans. The acidic environment they create, however, harms other bacteria and prevents these potentially dangerous bacteria from growing. So, overall, the food that's being preserved will have predominantly only one type of bacteria in it, which is not harmful to humans.
endospore
Bacillus anthracis are rod shaped, gram positive bacteria. Their endospores are the infectious agents of anthrax. The infection is fatal in both animals and humans. The major symptoms are vomiting blood, respiratory collapse, severe diarrhea, skin lesions with boils, and acute inflammation.
These bacteria did not become antibiotic resistant until we overused antibiotics. This is one of my pet peeves. We selected for these 'bad bugs' in this way. The CDC says: Many public health organizations have described the rapid emergence of resistant bacteria as a “crisis” or “nightmare scenario” that could have “catastrophic consequences. We are just about back to where we were before the discovery of penicillin. And I remember those days.Among gram-positive pathogens, a global pandemic of resistant S. aureus (MRSA) and Enterococcus species currently are the biggest threat.Vancomycin-resistant enterococci (VRE) and the global spread of drug resistance among common respiratory pathogens, including Streptococcus penumoniae and Mycobacterium tuberculosis, is epidemic. And just what will we do with TB that doesn't respond to antibiotics.

It is beta-lactamase. This is a type of enzyme that is produced by bacteria that is resistant to certain antibiotics. These include Cephalosporinase and Penicillinase. These enzymes destroy Cephalosporins and Penicillins respectively.

ptalonomy is a chemical compound produced by bacteria
It can be produced by bacteria in a lab.

That means you want to know about the antibiotics. By definition the antibiotics are chemical substances produced by one type of micro organisms to inhibit the growth of other types of micro organisms. They can work in high dilution. Most of the antibiotics are produced by the fungi. Only few in clinical practice are produced by the bacteria. Few of them are used to prevent the diseases. Most are used to treat the diseases. By the way, multi drug resistant bacteria is the biggest problem of the day.
