The present study was aimed to evaluate the suitability of agro-wastes and crude vegetable oils for cost-effective production poly-?-hydroxybutyrate (PHB), growth kinetics PHB in Alcaligenes faecalis RZS4 Pseudomonas sp. RZS1 with these carbon substrates biodegradation accumulated by cultures. accumulates higher amounts corn (79.90% dry cell mass) rice straw (66.22% medium respectively. kinetic...

The arsenite oxidase (Aio) from the facultative autotrophic Alphaproteobacterium Rhizobium sp. NT-26 is a bioenergetic enzyme involved in the oxidation of arsenite to arsenate. The enzyme from the distantly related heterotroph, Alcaligenes faecalis, which is thought to oxidise arsenite for detoxification, consists of a large α subunit (AioA) with bis-molybdopterin guanine dinucleotide at its ac...

The new pleuromutilin derivative 81.723 hfu is extremely active against gram-positive organisms such as streptococci, staphylococci, and against mycoplasmas. A number of Shigella, Klebsiella, and Escherichia coli strains were also found to be quite susceptible to this new agent, whereas other gram-negative organisms like Pseudomonas aeruginosa, Proteus species, and Alcaligenes faecalis proved t...

Soil salinization is increasing steadily in many parts of the world and causes major problems for plant productivity. Under these stress conditions, root-associated beneficial bacteria can help improve plant growth and nutrition. In this study, salt-tolerant bacteria from the rhizosphere of Uzbek wheat with potentially beneficial traits were isolated and characterized. Eight strains which initi...

After the growth of Paecilomyces persicinus P-10 in a glucose-peptone medium, filtrates were collected and analyzed for antibiotic antivity. Activities against Salmonella gallinarum ATCC 3030 and Alcaligenes faecalis ATCC 8750 (penicillin N-resistant strain) were obtained. Part of the former activity was readily inactivated by penicillinase. The fraction active against A. faecalis was isolated ...

The Pseudomonas stutzeri strain A1501 (formerly known as Alcaligenes faecalis) fixes nitrogen under microaerobic conditions in the free-living state and colonizes rice endophytically. The authors characterized a region in strain A1501, corresponding to most of the nif genes and the rnf genes, involved in electron transport to nitrogenase in Rhodobacter capsulatus. The region contained three gro...

In this study, a novel betaproteobacterium, strain DPN7(T), was isolated under mesophilic conditions from compost because of its capacity to utilize the organic disulfide 3,3'-dithiodipropionic acid. Analysis of the 16S rRNA gene sequence of strain DPN7(T) revealed 98.5 % similarity to that of Tetrathiobacter kashmirensis LMG 22695(T). Values for sequence similarity to members of the genera Alc...
