Increasing Yields of Extracellular Enzymes
1979Publisher Summary This chapter discusses the current rationales and methodologies employed to increase the extracellular enzyme yields. The four aspects considered are strain selection, environmental control, genetic regulatory controls, genetic recombination, and gene amplification techniques.

The involvement of extracellular enzymes in the metabolism ofBdellovibrio
Archives of Microbiology, 19741. Three host-independent (H-I)Bdellovibrio species are stimulated in growth by addition to the medium of cell-free host extracts. A mixture of fifteen labeled amino acids was used to follow incorporation of counts into trichloroacetic acid (TCA) insoluble material. No label was recovered in the nucleic acids. 2.

Production of extracellular enzymes in continuous culture
Folia Microbiologica, 1982The production of bacterial enzymes in batch fermentations is compared with results obtained in continuous culture. When studying the production of alpha-amylase in Bacillus subtilis it was found that instability of the enzyme synthesis was due to nonhomogeneity of the population rather than to "the culture's history" (i.e.

Extracellular Enzymes of Penicillium
1987The wide range of extracellular enzymes produced by species of Penicillium play an important role in the microbiological breakdown of organic materials. Notable examples of hydrolases of Penicillium include various cellulolytic enzymes and other polysaccharases, such as α- and β-glucanases, hemicellulases, and pectic enzymes, together with a variety of

Extracellular enzymes and the pathogenesis of nematophagous fungi
Applied Microbiology and Biotechnology, 2007Nematophagous fungi are an important group of soil microorganisms that can suppress the populations of plant-parasitic nematodes. The pathogenic mechanisms of nematophagous fungi are diverse: They can be parasitical-mechanical through producing specialized capturing devices, or toxin-dependent.

Extracellular Enzymes in Soils
Microbe Magazine, 2015I found the recent article in Microbe (April 2015, p. 178) in the Small Things Considered section (“Microbe, Enzyme or Mineral? a Riddle in the Soil”) interesting and appreciated the focus on extracellular enzymes in soils. However, the presentation leaves the reader with the impression that the paper reviewed (J. Blankinship et al., Soil Biol. Biochem.

Molecular Biology of Extracellular Enzymes
1979Publisher Summary This chapter discusses the process of secretion of enzymatic and nonenzymatic proteins (for example, binding proteins) in both gram-positive and gram-negative bacteria. The chapter examines the increasing evidence that indicates that these secretory proteins are synthesized from membrane-bound polyribosomes in precursor form and are

EXTRACELLULAR ENZYMES FROM STRAINS OF SORANGIUM
Canadian Journal of Microbiology, 1965Soil organisms belonging to the myxobacter group and predatory on molds, yeasts, nematodes, and streptomycetes as well as on a wide range of bacteria elaborate at least two extracellular enzymes: a protease and a lysin. The protease hydrolyzes casein and haemoglobin and is inactive against bacterial cell walls while the lysin hydrolyzes bacterial cell ...

1992
This Chapter describes the methods used for the assay, identification and determination of “toxic” action of extracellular enzymes of microbial (mainly fungal) and higher plant origin involved in plant pathogenesis. Methods used for the general characterization of an enzyme, such as its catalytic properties, molecular weight, amino acid composition ...

Commercial Production of Extracellular Enzymes
2014This chapter discusses production strains and the regulation of extracellular-enzyme expression. The chapter also analyzes the properties of amylases and cellulases produced by Bacillus spp., with comparisons to similar enzymes made by other microorganisms. Almost all of the extracellular enzymes in Bacillus spp.
