13. PCR-Based Genotyping of Epidemic and Preepidemic Trichoderma Isolates Associated with Green Mold of Agaricus bisporus
We used randomly amplified polymorphic DNA (RAPD)-PCR to estimate genetic variation among isolates of Trichoderma associated with green mold on the cultivated mushroom Agaricus bisporus. Of 83 isolates examined, 66 were sampled during the recent green mold epidemic, while the remaining 17 isolates were collected just prior to the epidemic and date back to th

14. Morphological and Molecular Identification of Trichoderma Isolates on North American Mushroom Farms
Green mold disease (causal agent, Trichoderma) has resulted in severe crop losses on mushroom farms worldwide in recent years. We analyzed 160 isolates of Trichoderma from mushroom farms for morphological, cultural, and molecular characteristics and classified these isolates into phenotypic groups. The most common group comprised approximately 40% of the iso

15. Biological Control of Olive Green Mold in Agaricus bisporus Cultivation
Successful methods to control the damaging weed mold Chaetomium olivaceum (olive green mold) in mushroom beds are not presently known. An attempt was made to control C. olivaceum by biological means. A thermophilic Bacillus sp. which showed dramatic activity against C. olivaceum on Trypticase soy agar (BBL Microbiology Systems)-0.4% yeast extract agar plates

16. Analysis of an Effective Antibiotic (Chaetomacin) Isolated from a Thermophilic Bacillus sp. Against Olive Green Mold
Successful methods to control the damaging weed mold Chaetomium olivaceum (olive green mold) in mushroom beds are not known. An effective antibiotic (named chaetomacin) against C. olivaceum was isolated from a thermophilic Bacillus sp. This compound was shown to be an extremely potent and stable antibiotic, effective over a wide range of both pH (2 to 10) an

17. Pulmonary Infection Caused by Gymnascella hyalinospora in a Patient with Acute Myelogenous Leukemia
We report the first case of invasive pulmonary infection caused by the thermotolerant ascomycetous fungus Gymnascella hyalinospora in a 43-year-old female from the rural midwestern United States. The patient was diagnosed with acute myelogenous leukemia and treated with induction chemotherapy. She was discharged in stable condition with an absolute neutrophi

18. Studies on the biosynthesis of aspergillin by Aspergillus niger.
Two inhibitors of the biosynthesis of aspergillin, the black spore pigment of Aspergillus niger, have been investigated. 2,4-Dithiopyrimidine exerted its inhibitory effect by intracellularly chelating cupric ion required for normal pigmentation. Dimethylsulfoxide prevented the synthesis of certain phenolic precursors of the native pigment. Partial purificati

19. The reductive tricarboxylic acid cycle of carbon dioxide assimilation: initial studies and purification of ATP-citrate lyase from the green sulfur bacterium Chlorobium tepidum.
Carbon dioxide is fixed largely by the reductive tricarboxylic acid (RTCA) cycle in green sulfur bacteria. One of the key enzymes, ATP-citrate lyase, was purified to apparent homogeneity from the moderately thermophilic green sulfur bacterium Chlorobium tepidum. The molecular weight of the native enzyme was about 550,000, and the preponderance of evidence in

20. Antigenic characterization of Penicillium camemberti and related common cheese contaminants.
Twenty-four isolates of Penicillium (including a green-spored mutant from a French Brie cheese, Penicillium camemberti) with a proposed relationship to the white cheese mold P. camemberti were investigated by immunological procedures. These penicillia, which are representative of species that have caused considerable taxonomic confusion, had common micromorp

21. Lipolytic fermentations of stickwater by Geotrichum candidum and Candida lipolytica.
Stickwater, a by-product of the fish meal and oil industry, is an aqueous suspension of fish proteins, lipids, and other materials, and also contains soluble nonprotein nitrogen but not carbohydrate. It is usually partially evaporated by heat to a marketable form called "fish solubles," which is sold with an acid preservative as an animal feed supplement. Ho

22. Effect of Metabolites Produced by Trichoderma harzianum Biotypes and Agaricus bisporus on Their Respective Growth Radii in Culture
Trichoderma harzianum biotypes Th1, Th2, and Th3 produced volatile metabolites in vitro which had similar fungistatic effects on the growth of Agaricus bisporus. Metabolites present in agar colonized by these strains also inhibited mycelial growth of A. bisporus, although the reduction in growth was less in the presence of metabolites produced by biotype Th2

23. Molecular Characterization and Identification of Biocontrol Isolates of Trichoderma spp.
The most common biological control agents (BCAs) of the genus Trichoderma have been reported to be strains of Trichoderma virens, T. harzianum, and T. viride. Since Trichoderma BCAs use different mechanisms of biocontrol, it is very important to explore the synergistic effects expressed by different genotypes for their practical use in agriculture.

24. The secretory pathway of protists: spatial and functional organization and evolution.
All cells secrete a diversity of macromolecules to modify their environment or to protect themselves. Eukaryotic cells have evolved a complex secretory pathway consisting of several membrane-bound compartments which contain specific sets of proteins. Experimental work on the secretory pathway has focused mainly on mammalian cell lines or on yeasts. Now, some
