Nitrogen is an essential plant nutrient, widely applied as N-fertilizer to improve yield of agriculturally important crops. An interesting alternative to avoid or reduce the use of N-fertilizers could be the exploitation of plant growth-promoting bacteria (PGPB), capable of enhancing growth and yield of many plant species, several of agronomic and ecological significance. PGPB belong to diverse...

Splenic abscesses caused by Streptococcus bovis are rarely reported in the literature and are mainly seen in patients with endocarditis and associated colonic neoplasia/carcinoma. We report the first case of splenic abscess caused by Streptococcus gallolyticus subsp. pasteurianus (Streptococcus bovis biotype II/2) as presentation of a pancreatic cancer.

BACKGROUND Pyruvate decarboxylase (PDC) is a well-known pathway for ethanol production, but has not been demonstrated for high titer ethanol production at temperatures above 50 °C. RESULT Here we examined the thermostability of eight PDCs. The purified bacterial enzymes retained 20% of activity after incubation for 30 min at 55 °C. Expression of these PDC genes, except the one from Zymomonas ...

Bacterial cellulose- Curcuma Longa Linn from acetobacter xylinum has been produced. The aim of research: To isolate Cellulose-Curcuma Acetobacter and to improve activity catalitic bacterial cellulose. Morphology properties was carried out on sample cellulose extract. This characteristic test by Scanning Electron Microscope (SEM).

A new screening method for inhibitors of cellulose biosynthesis is described. This method utilized three microbial strains; a cellulose-containing fungus Phytophthora, and a cellulose non-containing fungus Candida, and a bacterial strain of Acetobacter, a cellulose-producing acetic acid bacterium. The primary screen examined microbial cultures for selective growth inhibition against Phytophthor...

A novel species of acetic acid bacteria belonging to the genus of Acetobacter, to which a scientific name of Acetobacter altoacetigenes MH-24 (FERM BP-491) is given. The bacteria can grow in a culture medium con taining at least 4 w/v. 9% of acetic acid with a pH of 3.5 at the highest. Pure samples of species have been iso lated and used for the fermentation production of vine gar without under...
