Cellulose degrading bacteria from koala faeces were isolated using caboxymethylcellulose-Congo red agar, screened in vitro for different hydrolytic enzyme activities and phylogenetically characterized using molecular tools. Bacillus sp. and Pseudomonas sp. were the most prominent bacteria from koala faeces. The isolates demonstrated good xylanase, amylase, lipase, protease, tannase and lignin p...

The characteristics of Ca2+-activated ATPase activities previously often postulated as components for the calcium transporting system in fish gills do not fulfil the requirements of a transport Ca2+-ATPase. The chelation of Ca2+- or Mg2+-ions is a prerequisite for the adenosinephosphate esters to serve as substrate for gill plasma membrane phosphatases. Ca2+-activated ATP hydrolysis results fro...

1. The characteristics of Ca2+-activated ATPase activities previously often postulated as components for the calcium transporting system in fish gills do not fulfil the requirements of a transport Ca: '-ATPase. 2. The chelation of Ca;~or Mg:~-ions is a prerequisite for the adenosinephosphate esters to serve as substrate for gill plasma membrane phosphatases. 3. Ca2+-activated ATP hydrolysis res...

Tailed double-stranded DNA (dsDNA) bacteriophages frequently harbor structural proteins displaying peptidoglycan hydrolytic activities. The tape measure protein from Staphylococcus aureus bacteriophage vB_SauS-phiIPLA35 has a lysozyme-like and a peptidase_M23 domain. This report shows that the lysozyme-like domain (TG1) has muramidase activity and exhibits in vitro lytic activity against live S...
