Answer 1

Malachite green residue can affect aquaculture food safety,Bio remediation of condaminated water by enzyme treatment is an envirornmently friendly and economical way to remove condaminating substances.In the present study, a temperature and PH stable laccase was purified from the spores of bacillus ballismortis fmb-103 and was used to degrade malachite green

It is clear that the cells under going degeneration differ from the normal ones on lower use of sugar,in lower prodution of butanol and isopropyl alcohol, and in increased production of butyric acid.Cultures undergoing degeneration produced no polysaccharide and starch formation was not detected by iodine.

Changes in the metabolism of a strain of clostridium butylicum undergoing degeneration in subcultures without heat shock treatement have been investigated. After degeneration stated, the strain used up less sugar and produced progressively less butyric acid. The culture usually died out after the 12 to 15th passage.

Identification of anaerobics recovered from clinical samples is complicated by the fact that certain gram positive anaerobes routinely stain gram negetive. When anaerobic bacteria are exposed to oxygen a break down of the physical integrity of the cell wall occures introducing gram stain variablity in gram positive anaerobes.
