Isolation and classification of proteolytic bacteria from the bovine rumen
Colony counts of proteolytic ruminal bacteria in the order of 1 x 10⁹ organisms per gram of whole rumen contents and total colony counts in the order of 2 to 3 x 10⁹ organisms per gram were obtained from rumen contents of cattle fed a maintenance ration of hay and grain. The proteolytic counts …

The development of differential media for the isolation of proteolytic bacteria from the rumen
Two media were adapted to the culture of proteolytic bacteria from the bovine rumen. Modifications were made in the double indicator dairy medium of Donovan and Vincent (SRBP) and in the medium of Hungate for rumen bacteria (SRP). Modifications included use of plant protein suspensions, casein, and …

Responses of Rumen Microflora to Whey Products Added to High-Grain Low-Roughage Rations
… affect the numbers and types of protozoa and bacteria in the rumen. A small particle size of feed and a fast rate of passage of the feed through the ruminant decreases protozoal numbers. Full feeding of a concentrate ration and an acid pH in the rumen also tend to reduce protozoa numbers. …

Environment risk assessment for toxic chemicals and genetically-engineered microorganisms: a microcosm approach
… and wild type strain on indigenous bacteria belonging to specific functional groups important in nutrient cycling were similar: inoculation of either strain caused a temporary increase in densities of total and proteolytic bacteria, while it did not affect amylolytic and pectolytic …

Contribuição da microbiota bacteriana para o processo digestivo e desenvolvimento da lagarta da soja (Anticarsia gemmatalis) e caracterização de bactérias proteolíticas associadas ao seu trato intestinal
… mais eficiente na supressão do crescimento bacteriano foi a tetraciclina, que alcançou uma inibição substancial nas doses testadas. Análises microscópicas mostraram que o intestino de A. gemmatalis criadas com dieta controle, possui uma abundante microbiota, porém com pouca diversidade. …
