The respiratory metabolism of Schizosaccharomyces pombe 972h(-), a fission, haplontic, "petite negative" yeast, was studied. Glucose and glycerol are good growth substrates and are oxidized under appropriate conditions. l-Lactate, ethanol, malate, and succinate are oxidized but are poor substrates for growth. d-Lactate and pyruvate are neither oxidized nor used for growth. Limited growth was observed under anaerobic conditions. The addition of 0.3% KNO(3) to a rich medium relieves the oxygen requirement. A continuous increase of cell respiration during growth on repressive concentration of glucose was observed, suggesting the presence of glucose repression of respiration. Reduced nicotinamide adenine dinucleotide (NADH), succinate, alpha-glycerophosphate, and ascorbate plus tetramethyl-p-phenylenediamine are oxidized by a mitochondrial fraction. NADH and succinate oxidations are inhibited by antimycin A and NaCN but not by rotenone, suggesting the absence of the phosphorylation site I and the presence of sites II and III. The effects of several mitochondrial inhibitors on growth and respiration indicate that the requirement of an oxidant for growth is related neither to the functioning of the respiratory electron transport chain nor to the formation of respiratory energy. The previously suggested correlations between the nonviability of vegetative "petites" mutants, the absence of repression of respiration by glucose, and the incapacity to grow under anaerobic conditions are thus not strictly valid for S. pombe.

Lactic acid bacteria (LAB) from traditional fermented sausages of the Basilicata region were investigated by ARDRA-PCR and RAPD-PCR for taxonomic identification at species and strain level and characterized on the basis of the growth and acidification at different temperatures, incubation times, levels of NaCl and KNO(2), hydrolysis of sarcoplasmatic and myofibrillar proteins and antimicrobial, peptide/amino acid release and nitrate reductase activities. Lactobacillus sakei was the predominant species (67%) followed by Pediococcus pentosaceus (16%), Leuconostoc carnosum (8%), Lactobacillus plantarum (4%), Lactobacillus brevis (2%) and Leuconostoc pseudomesenteroides (2%). The technological characterization revealed that most of the isolates had good acidifying and proteolytic properties. Moreover, Lb. sakei strains showed antimicrobial ability, while Leuconostoc strains the highest reduction of nitrates. This work was a preliminary study in the formulation of autochthonous starter cultures in order to standardize the production process of sausages, to preserve their typical organoleptic and sensory characteristics and to improve the quality of final product.
