1. Bacteriological control of mosquitoes and blackflies: present aspects and perspectives of research.
O controle biologico de mosquitos e borrachudos que transmitem graves doencas, e feito principalmente com Bacillus thuringiensis israelensis (Bti) e Bacilus sphaerfcus. A inexistencia de toxicidade para outros organismos comn os quais se relaciona no meio ambiente, favoreceu a sua utilizacao nos programas de controle de vetores. O Bti e utilizado nao so no c

2. Microbiota bacteriana dominante cultivável no trato digestivo do urubu (Coragyps atratus Bechstein 1793)
As bactérias anaeróbias estritas e facultativas cultiváveis do trato digestivo de seis urubus (Coragyps atratus Bechstein 1793) foram isoladas e identificadas. Após a captura, as aves receberam uma alimentação de baixa contaminação durante uma semana para eliminar possíveis microorganismos alóctonos. A seguir, amostras colhidas na língua, estomago

3. Mosquitocidal bacterial toxins: diversity, mode of action and resistance phenomena
Bacteria active against dipteran larvae (mosquitoes and black flies) include a wide variety of Bacillus thuringiensis and B. sphaericus strains, as well as isolates of Brevibacillus laterosporus and Clostridium bifermentans. All display different spectra and levels of activity correlated with the nature of the toxins, mainly produced during the sporulation p

6. TAXONOMY OF CLOSTRIDIUM BIFERMENTANS AND CLOSTRIDIUM SORDELLII I. : Their Toxigenicity, Urease Activity, and Sporulating Potency
Nishida, S. (Kanazawa University, Kanazawa, Japan), K. Tamai, and T. Yamagishi. Taxonomy of Clostridium bifermentans and Clostridium sordellii. I. Their toxigenicity, urease activity, and sporulating potency. J. Bacteriol. 88:1641–1646. 1964.—Strains with properties similar to those of Clostridium bifermentans were usually obtained by selecting heat-resi

7. Differentiation Between Clostridium sordellii and Clostridium bifermentans by Gas Chromatography
Clostridium bifermentans can be differentiated from Clostridium sordellii by gas chromatography on the basis of amines detected after growth for 6 hr in cookedmeat medium. Products detected after exposure of resting cells to amino acids gave evidence for the probable origin of the amines.

8. Biochemical properties of Clostridium bifermentans spores.
As previously found for spores of Bacillus species, dormant spores of Clostridium bifermentans contained essentially no adenosine triphosphate, a high level of adenosine monophosphate, a high level of 3-phosphoglyceric acid, and much transfer ribonucleic acid lacking a 3'-terminal adenosine monophosphate residue. As in spores of Bacillus species, germination

9. Taxonomic Implications of Spore Fine Structure in Clostridium bifermentans
Thirty-five strains of Clostridium bifermentans were, in most part, culturally homogeneous by conventional taxonomic criteria but were heterogeneous with respect to spore fine structure. Fourteen of the strains produced spores with appendages, distributed among four distinct ultrastructural types. No consistent correlation existed between spore type and othe

10. Identification of Several Unique, Low-Molecular-Weight Basic Proteins in Dormant Spores of Clostridium bifermentans and Their Degradation During Spore Germination
Two acid-soluble, low-molecular-weight basic proteins comprise ∼20% of the protein in dormant spores of Clostridium bifermentans. Both of these proteins are rapidly degraded during spore germination.

11. Appendages of Clostridium bifermentans Spores
Four distinct spore appendage types were detected in an electron microscope survey of 12 strains of Clostridium bifermentans. A smooth tubular appendage and a feather-like appendage are described in detail. In addition, hirsute tubular appendages and small pin-like appendages are depicted. Spores of four strains apparently lack appendages.

12. Cloning and expression of the phospholipase C gene from Clostridium perfringens and Clostridium bifermentans.
The phospholipase C gene from Clostridium perfringens was isolated, and its sequence was determined. It was found that the structural gene codes for a protein of 399 amino acid residues. The NH2-terminal residues have the typical features of a signal peptide and are probably cleaved after secretion. Escherichia coli cells harboring the phospholipase C gene-c
