Among the bacilli, gram positive Bacillus anthracis, Corynebacterium diphtheriae, Clostridium species are highly sensitive. Among the spirochetes. Treponema pallidum is highly sensitive to penicillin.

Bacillus sp. These bacteria are gram-positive soil microbes. Members of the Bacillus species supply 58% of iadustrial enzymes sold (19). Eor example, proteases from B. amjloliquefaciens and amylases from B. licheniformis glucose isomerase from B. coagulans are used ia a variety of iadustrial processes (see Enzyme applications-industrial). The proteiaaceous iaclusioas produced by B. thuringiensis are useful as iasect toxias. Thus exteasive fermentation technology has been developed for Bacillus species and low cost media are available (19). 

Oxeta.nocins, Oxetanocia A (49), formerly oxetanocia, is the first naturally occurring oxetanose derivative and is isolated from Bacillus megaterium (1,145). It inhibits gram-positive bacteria, herpes vimses, and human immunodeficiency vims (HIV) (146). The chemical synthesis of (49) and several derivatives has been reported (147). 

These compounds showed a remarkable activity toward Gram-positive (e.g.. Bacillus cereus, Staphylococcus aureus, Sarcina luted) and Gram-negative bacteria (e.g.. Pseudomonas sp.) the activity was somewhat lower in the styryl derivatives (82MI2). 

Biological testing of these compounds against some Gram-positive and Gramnegative bacteria species showed that all prepared substances had a remarkable bacterial activity against Bacillus cereus.

The Gram-positive bacteria Bacillus subtilis, Bacillus megaterium and Bacillus brevis are also used for heterologous expression. Terpe [13] presented a table with some pharmaceutically and industrially relevant proteins expressed with this host. It is the most used prokaryotic host after... 

In the Gram-positive bacterium Bacillus subtilis (DNA with low G + C content), three Fur-like proteins have been characterized (Bsat et al., 1998). One, called Fur, regulates mainly iron uptake and siderophore biosynthesis. A second one, called PerR, regulates peroxide stress response genes and acts with manganese as corepressor. A third one, Zur, regulates genes for zinc uptake. The Zur protein found in E. coli shows only 25 % identity to the B. subtilis Zur, while the two Fur proteins have 32 % identical amino acids.

The cell walls of most Gram-positive bacteria contain (1 ->3) poly(glycerol phosphate) teichoic acids which can bear D-alanyl or glycosyl substituents.56 However, the cell walls of Bacillus stearothermophilus B65 contain a glycerol teichoic acid which is free of substituents.57 This is contrary to evidence that had been obtained from biosynthetic studies.58... 

Bacillus Bacilli are characterized as Gram-positive aerobic microorganisms which produce endospores. This genus is heterotrophic and diverse, comprising 10% of the bacterial population.
