Abstract
The discovery of biomolecules has been the subject of extensive research for several years due to their potential to combat harmful pathogens that can lead to environmental contamination and infections in both humans and animals. This study aimed to identify the chemical profile of endophytic fungi, namely Neofusicoccum parvum and Buergenerula spartinae, which were isolated from Avecinnia schaueriana and Laguncularia racemosa. We identified several HPLC-MS compounds, including Ethylidene-3,39-biplumbagin, Pestauvicolactone A, Phenylalanine, 2-Isopropylmalic acid, Fusaproliferin, Sespendole, Ansellone, Calanone derivative, Terpestacin, and others. Solid-state fermentation was conducted for 14-21 days, and methanol and dichloromethane extraction were performed to obtain a crude extract. The results of our cytotoxicity assay revealed a CC50 value > 500 μg/mL, while the virucide, Trypanosoma, leishmania, and yeast assay demonstrated no inhibition. Nevertheless, the bacteriostatic assay showed a 98% reduction in Listeria monocytogenes and Escherichia coli. Our findings suggest that these endophytic fungi species with distinct chemical profiles represent a promising niche for further exploring new biomolecules.

Abstract
2-Isopropylmalic acid (2-IPMA) and 3-isopropylmalic acid (3-IPMA), recently discovered in wines, were simultaneously quantified in forty wines by UHPLC-MS/MS triple quadrupole. Principal component analysis displayed that red wines were more correlated with high amounts of 2-IPMA (average content 31.60 mg/L); white wines were mostly characterized by low levels of both organic acids. No correlation of theirs levels to other wine features (wine ageing or alcoholic content) were found. 2-IPMA and 3-IPMA showed MICs values of 4096 mg/L and MBCs values of 8192 mg/L or higher against several food borne pathogens. In association, an interesting lower MIC and MBC values (2048 mg/L and 4096 mg/L respectively) were observed against Y. enterocolitica. Interestingly, 3-IPMA showed a mild antioxidant activity by DPPH assay (EC50 = 3940 mg/L), higher than that of 2-IPMA (EC50 > 4800 mg/L). No toxicity of these compounds against human colorectal and liver cells (TB assay) was observed.

Abstract
Polar lipid-derived fatty acids (PLFAs) and their stable carbon isotopes are frequently combined to characterize microbial populations involved in the degradation of organic matter, offering a link to biogeochemical processes and carbon sources used. However, PLFA patterns derive from multiple species and may be influenced by substrate types. Here, we investigated such dependencies by monitoring the transformation of position-specifically 13C-labeled amino acids (AAs) in coastal marine sediments dominated by heterotrophic bacteria. Alanine was assimilated into straight-chain FAs, while valine and leucine incorporation led to the characteristic production of even- and odd-numbered iso-series FAs. This suggests that identical microbial communities adjust lipid biosynthesis according to substrate availability. Transformation into precursor molecules for FA biosynthesis was manifested in increased 13C recoveries of the corresponding volatiles acetate, isobutyrate and isovalerate of up to 39.1%, much higher than for PLFAs (<0.9%). A significant fraction of 13C was found in dissolved inorganic carbon (up to 37.9%), while less was recovered in total organic carbon (up to 17.3%). We observed a clear discrimination against the carboxyl C, whereby C2 and C3 positions were preferentially incorporated into PLFAs. Therefore, position-specific labeling is an appropriate tool for reconstructing the metabolic fate of protein-derived AAs in marine environments.

Abstract
The copy number of 2 mu DNA-derived plasmids in CIR+ Saccharomyces cerevisiae transformants is determined by its selective marker and is usually much lower than that of the endogenous plasmid. Only plasmids containing the leu2 allele of pJDB219, designated as leu2-d, under selective conditions displayed a higher copy number than did endogenous 2 mu DNA and by displacement generated cured cells. Spontaneous loss of 2 mu DNA occurred with a frequency of about 0.02% per generation. Curing plasmids, like pMP78, have copy numbers of 35; noncuring plasmids, like pDB248 or YEp6, have copy numbers of 4 to 8. The 2 mu DNA copy number in strains AH22 and YNN27 were determined to be 40 and 100, respectively. The high copy number of leu2-d-containing plasmids can be explained by its weak expression of less than 5% that of the wild-type LEU2 gene. The leu2-d allele has a deletion of the 5'-end sequence starting from 29 base pairs before the ATG initiation codon, but surprisingly, its expression is still regulated. On YRp7, which contains the chromosomal autonomic replication sequence ARS1, the defective leu2-d allele could not complement a leu2 host strain. This suggests a more stringent control of replication of ARS1-containing plasmids than of 2 mu-containing plasmids.

Abstract
An inventory of the organic acids detectable by liquid-liquid extraction has been made in different Tokaj wines. After the separation of the acidic compounds in the aroma extracts using Na2CO3 and after the derivatization with diazomethane 65 methylester have been separated by gaschromatography and identified by mass spectrometry. Using a special fractionation method organic acids, amino acids, carbohydrates and phenolic compounds have been isolated in different groups. After the derivatization of the components 50 organic acids have been quantitatively determined by gaschromatography. The compositions of the acids in the wines differ considerably. The quantitative differences are caused by the vintages, the method of production and the kind of storage. The possible biosynthetic pathways of the various acids are discussed.

Abstract
1. Cell-free extracts, prepared from a non-fluorescent Pseudomonas grown on m-cresol, oxidized gentisate and certain alkyl-substituted gentisates with the consumption of 1 mol of oxygen and the formation of 1 mol of pyruvate from 1 mol of substrate. 2. In addition to pyruvate, malate was formed from gentisate; citramalate was formed from 3-methylgentisate and 4-methylgentisate; 2,3-dimethylmalate was formed from 3,4-dimethylgentisate. 3. One enantiomer, d-(-)-citramalate, was formed enzymically from 3-methylgentisate, 4-methylgentisate and citraconate. l-(+)-Citramalate was formed from mesaconate by the same extracts. When examined as its dimethyl ester by gas-liquid chromatography, enzymically formed 2,3-dimethylmalate showed the same behaviour as one of the two racemates prepared from the synthetic compound. 4. Maleate, citraconate and 2,3-dimethylmaleate were rapidly hydrated by cell extracts, but ethylfumarate and 2,3-dimethylfumarate were not attacked. 5. Cell extracts oxidized 1,4-dihydroxy-2-naphthoate to give pyruvate and phthalate. 6. Alkylgentisates were oxidized by a gentisate oxygenase (EC 1.13.1.4) present in Pseudomonas 2,5. The ring-fission products were attacked by maleylpyruvase, but not by fumarylpyruvase, and their u.v.-absorption spectra were those expected for alkyl-substituted maleylpyruvates. 7. When supplemented with ATP, CoA, succinate and Mg(2+) ions, an enzyme system from cells grown with 2,5-xylenol formed pyruvate from d- but not from l-citramalate. Extracts from cells grown with dl-citramalate or with itaconate attacked both d- and l-citramalate; other alkylmalates were cleaved in similar fashion to give pyruvate or 2-oxobutyrate. 8. These results accord with a general sequence of reactions in which the benzene nucleus of an alkylgentisate is cleaved to give an alkyl-substituted maleylpyruvate. The ring-fission products are hydrolysed to give pyruvate, plus alkylmalic acids which then undergo aldol fissions, probably as their CoA esters. In Pseudomonas 2,5 several homologous sequences of this general type appear to be catalysed by a single battery of enzymes with broad substrate specificities, whereas the metabolic capabilities of the fluorescent Pseudomonas 3,5 are more restricted. 9. Intact cells of both organisms metabolize d-malic acid by reactions that have not been elucidated, but are different from those which degrade alkylmalates.

Abstract
Cell-free extracts of Acetobacter suboxydans were prepared which were capable of condensing alpha-ketoisovalerate with (14)C-labeled acetyl-coenzyme A to yield (14)C-labeled alpha-isopropylmalate. The product of the reaction was isolated by paper and column chromatography and was characterized by recrystallization with synthetic alpha-isopropylmalic acid to constant specific radioactivity. The formation of alpha-isopropylmalate by extracts of A. suboxydans plus the ability of the organism to grow in a simple glucose-glycerol medium containing glutamic acid as the only amino acid indicate that the pathway for leucine biosynthesis shown to exist in yeast and Salmonella typhimurium also occurs in A. suboxydans. As a comparison, the condensation of oxalacetate and ((14)C) acetyl-coenzyme A to yield ((14)C) citric acid was shown, by similar means, to occur in A. suboxydans. This is of interest since the existence of this classical condensing enzyme has hitherto not been demonstrated in this organism. This reaction was further demonstrated in cell-free extracts of A. suboxydans by means of a spectrophotometric assay at 232 mmu which measured the cleavage of the carbon-sulfur bond of acetyl-coenzyme A in the presence of oxalacetate. Comparison of the specific activities of crude cell-free extracts indicated a much more extensive occurrence of this reaction in yeast than in A. suboxydans.
