WebThe bacterial plasmid contains DNA as genetic material, replicating independently and comprising antibiotic-resistant genes. Many antibiotic-resistant genes in bacteria are present in plasmids. The three necessary functional regions present within the plasmid are: An origin of replication WebThese bacteria thrive in anaerobic or oxygen poor environments. They belong to the order Chromatiales of proteobacteria. They utilize hydrogen sulfide or thiosulphates as a reducing agent and release sulphur. The main pigments are bacteriochlorophyll ‘a’ and ‘b’ located in the plasma membrane.

WebTypes of Rod-shaped Bacteria. Bacilli are bacteria that have rod-shaped cells. In that, some of these bacilli have peculiar shapes or arrangements as follows –. Diplobacilli – two rod-shaped bacilli arranged side by side. Eg., Klebsiella rhinoscleromatis. Streptobacilli – the bacilli are arranged in chains. Eg., WebGenus of bacteria lacking cell wall around its cell membrane Its traits make them resistant naturally to antibiotics which aim at the synthesis of cell wall They could be saprotrophic or parasitic Some of its species are pathogens to humans – M. pneumoniae, M. genitalium WebThe lifecycle of bacteria comprises four phases: The lag phase: In the lag phase, bacteria do not grow. They adjust to their environment and produce vitamins and amino acids needed for division. The log or exponential phase: During the log phase, bacteria divides rapidly by binary fission. maersk code of conduct
