ABSTRACT Forty isolates of endophytic bacteria isolated from banana tree roots were assessed as to their capacity to solubilize phosphate in a solid culture medium supplemented with different inorganic and one organic source of phosphorus. The amount of phosphorus (P) in each liquid medium was quantified, and an indirect assessment of acid phosphatase activity was performed. All assays had a fully randomized design, with three repetitions. Approximately 67.5% of the 40 isolates assessed in solid medium solubilized phosphorus from tricalcium phosphate and 7.5% of the isolates solubilized phosphorus from soy lecithin; no isolates exhibited P solubilization capacity in medium supplemented with iron phosphate. Acid phosphatase activity was detected in 65% of... Tipo: Info:eu-repo/semantics/article Palavras-chave: Acid phosphatase; Bacillus sp.; Lecithin; Musa spp.; PGPB..

Enzymes, and particularly proteases, have become an important and indispensable part of industrial processes such as laundry detergents, pharmaceuticals and food products. Detergents such as Tide®, Ariel® and Biz® contain proteolytic enzymes, most of them produced by members of the genus Bacillus. This paper describes the compatibility of protease produced by the thermophilic Bacillus sp, with commercial laundry detergent. Stability studies indicated that this enzyme retained about 95% and 74% of its maximum activity after 1h at 60ºC in the presence of glycine in combination with MnSO4 and CaCl2, respectively. No inhibitory effect was observed at 1.0-5.0 mM of EDTA. Triton X-100 inhibited the enzyme in all the concentrations tested. The enzyme was unstable...
