1. Enhanced production of prodigiosin by Serratia marcescens MO-1 using ram horn peptone
This work addresses the production of prodigiosin from ram horn peptone (RHP) using MO-1, a local isolate in submerged culture. First, a novel gram-negative and rod-shaped bacterial strain, MO-1, was isolated from the body of the grasshopper (Poecilemon tauricola Ramme 1951), which was collected from pesticide-contaminated fields. Sequence analysis of 16S rD

2. Avaliação da temperatura de indução e de fontes de nitrogênio na produção de proteína de superfície de Streptococcus pneumoniae em Escherichia coli recombinante
Doenças causadas por Streptococcus pneumoniae constituem um dos principais problemas de saúde pública mundial. A proteína A de superfície de pneumococo (PspA) é candidata em potencial a ser carreadora em vacina conjugada contra essa bactéria. Considerando as altas perdas inerentes às etapas de purificação e conjugação da proteína, é fundamental

3. Influência de peptonas vegetais no cultivo de streptococcus zooepidemicus para a produção de ácido hialurônico / Influence of vegetable peptones in streptococcus zooepidemicus cultivation for hyaluronic acid production
O ácido hialurônico (AH) é um polissacarídeo linear com vasta gama de aplicações médicas e farmacêuticas. Por esta razão, é essencial a obtenção do produto com elevado grau de pureza. Atualmente, há grande foco de pesquisa direcionado ao AH produzido por rota microbiana, utilizando extrato de leveduras (EL) como fonte de nitrogênio. Disso resul

4. Effect of Cultural Environment on the Blood Group Activity of Microorganisms1
Blood group activity was proven to be a property of the bacterium per se which possesses it, although such activity was influenced by the cultural environment of the organism. High concentrations of peptones having blood group activity were able to transfer this activity to inactive organisms; however, the conferred activity was proportional to the concentra

10. Nitrogen utilization in bacterial isolates from the equine cecum.
A total of 114 bacterial isolates were obtained from the cecal contents of two mature cecally fistulated horses on a habitat-simulating medium containing 40% energy-depleted cecal fluid. Of these isolates, 108 were maintained in pure cultures and were tentatively grouped on the basis of cell morphology and physiological characteristics. Gram-negative rods (5

11. Lysis of Halobacteria in Bacto-Peptone by Bile Acids
All tested strains of halophilic archaebacteria of the genera Halobacterium, Haloarcula, Haloferax, and Natronobacterium lysed in 1% Bacto-Peptone (Difco) containing 25% NaCl, whereas no lysis was observed with other strains belonging to archaebacteria of the genera Halococcus, Natronococcus, and Sulfolobus, methanogenic bacteria, and moderately halophilic e

12. Preparation and evaluation of two microbiological media from shrimp heads and hulls.
Two peptones were extracted from raw shrimp waste after autolytic digestion. Digests were derived from shrimp heads and shrimp hulls, both of which are by-products of the shrimp processing industry. Digests were evaluated for suitability in supporting growth of microorganisms by measuring the total cell mass produced by five genera of bacteria and five gener
