A Pseudomonas sp PS-102 recovered from Muttukkadu brackish water lagoon, situated south of Chennai, showed significant activity against a number of shrimp pathogenic vibrios. Out of the 112 isolates of bacterial pathogens comprising Vibrio harveyi, V. vulnificus, V. parahaemolyticus, V. alginolyticus, V. fluvialis, and Aeromonas spp, 73% were inhibited in vitro by the cell-free culture supernatant of Pseudomonas sp PS-102 isolate. The organism produced yellowish fluorescent pigment on King's B medium, hydrolysed starch and protein, and produced 36.4% siderophore units by CAS assay and 32 μM of catechol siderophores as estimated by Arnow's assay. The PS-102 isolate showed wide ranging environmental tolerance with, temperatures from 25 to 40 °C, pH from 6 to 8, salinity from 0 to 36 ppt, while the antagonistic activity peaked in cultures grown at 30 °C, pH 8.0 and at 5 ppt saline conditions. The antagonistic activity of the culture supernatant was evident even at 30% v / v dilution against V. harveyi. The preliminary studies on the nature of the antibacterial action indicated that the antagonistic principle as heat stable and resistant to proteolytic, lipolytic and amylolytic enzymes. Pseudomonas sp PS 102 was found to be safe to shrimp when PL-9 stage were challenged at 107 CFU ml−1 and by intramuscular injection into of ∼5 g sub-adults shrimp at 105 to 108 CFU. Further, its safety in a mammalian system, tested by its pathogenicity to mice, was also determined and its LD50 to BALB/c mice was found to be 109 CFU. The results of this study indicated that the organism Pseudomonas sp PS 102 could be employed as a potential probiont in shrimp and prawn aquaculture systems for management and control of bacterial infections

Se describen los actos de inauguración de las nuevas ciento dos aulas de audición colectiva del Bachillerato Radiofónica promovidas por la Comisaría de Extensión Cultural en Cádiz, Murcia y Tenerife, en las que recibirán formación, por procedimientos radio-auditivos 6000 alumnos. El encargado de presidir dichos actos es el Director General de Enseñanza Media, Profesor González Álvarez, acompañado del Inspector General y Secretario Técnico de la Dirección General, Sr. Del Arco. Se reproduce el discurso del Director General en el que pone de manifiesto su satisfacción al saber que se cubrirán las necesidades de formación de muchos alumnos interesados en completar su instrucción. Seguidamente, se describe la visita de estas autoridades al Instituto Femenino de Cádiz y la posterior inauguración de otras tres Aulas de Audición en la localidad de Alcalá de los Gazules. Culminó su periplo por tierras gaditanas con la visita al Instituto masculino 'Columela' en Cádiz, dónde conversó con los profesores sobre distintos aspectos de la enseñanza.
