“…The cultural and morphological characteristics of fungal colonies were observed, and the identification was performed according to different manuals (Barnet & Hunter 1987;Pitt 1988;Klich & Pitt 1994). Bacteria were typified according to Gram staining and biochemical tests (Sneath et al 2000). Bacillus sp.…”

Experiments were designed (1) to investigate the bioadhesion, biofilm formation, foxing, and micropitting in documentary collections, (2) to assess the risk of biodeterioration, (3) to investigate the environmental microbial concentration, and (4) to study the influence of environmental factors in biodeterioration of documentary heritage in three archives. The importance of this work in the field of biodeterioration of documentary heritage was verified by bioadhesion and biofilm formation by microorganisms isolated from the collections under study. Bacillus sp. and Scopulariopsis sp. isolated from paper books showed considerable evidence of attacking the paper structure and of pigment production, constituting a hazard to the loss of documentary heritage.

“…Starch hydrolysis test (5) on Starch Nutrient Agar (SNA) was used to screen out the bacteria having the potentiality to produce amylase enzyme. Casein (Milk protein) hydrolysis test (6) on Skim Milk Agar (SMA) was performed to identify proteolytic activity. For this test, SNA and SMA plates were point inoculated with test organisms and the plates were incubated at 37°C for 24 h. After incubation, the surface of the SNA plates was flooded with iodine solution.…”

This study aimed to isolate biotechnologically important enzyme like amylase and protease producing rhizobacteria from rhizospheric soil. Soil samples were collected from the rhizospherc of five different flowering plants from Curzon hall, University of Dhaka. A good number of bacteria were isolated. Among them 12 bacterial isolates were selected for detailed study based on their amylolytic and proteolytic activity. Starch hydrolysis ratio (SHR) of the studied isolates ranged in between 2.06 and 4.67, casein hydrolysis ratio (CHR) ranged in between 2.27 and 3.92. All the selected isolateswere Gram positive and rod shaped and provisionally identified as the member of the genus Bacillus with five different species viz. Bacillus alcalophilus, B. subtilis, B. pumilus, B. firmus and B. lentus. Amylase and protease production of the studied bacteria were estimated and it was ranged in between 29.11±9.57 to 35.78 ± 9.05 and 230.27±37.08 to 276.47 ± 55.01 U/ml. The highest amylase and protease producer were Bacillus alcalophilus (Ce104/S9/L) which could produce 35.78 ± 9.05 U/ml and Bacillus subtilis (Ca71/S5/L) could produce 276.47 ± 55.01 U/ml of protease, respectively. Maximum production of both amylase and protease was achieved in 24 h of incubation period at 37°C and pH 7.0. Dhaka Univ. J. Biol. Sci. 32(1): 65-71, 2023 (January)

“…Plates were incubated at 37 ºC for 48 hrs, a typical colony, which appears peacock blue-coloured and surrounded by precipitation zone were counted and tested for further specific identification [26]. Purification and Identification of the isolated strains:-Three to five suspected isolates of each organism, isolated from each positive sample, were subjected for identification using the microscopic examination as well as their chemical and biochemical confirmation tests according to Bergy's Manual [30]…”

“…Table (2) summarizes the number of examined samples and the bacterial isolates detected, and their percentages. As shown in Table (2) all the selected 66 isolates of different pathogens bacteria were subjected to identification according to their morphological, physiological and biochemical characteristics as described in Bergy's manual of determinative Bacteriology [30]. Twenty typical isolate were picked up from Baird Parker media agar, 15 typical isolate were picked up from sorbitol MacConkey agar, 15 typical isolate were picked up from Yersinia selective agar medium, 15 typical isolate were picked up from Salmonella &Shigella ager and 20 typical isolate were picked up from Bacillus cereus agar medium.…”

Thirty burger samples were randomly collected from food shops super marks in microbiologically investigated for the presence of some pathogenic microorganisms including Escherichia coli 0157:H7, Salmonella typhimurium, aureus and Bacillus cereus were detected in 60% of the examined samples with an average counts of 14x10 5.1x10 2 cfu/g. however, Escherichia coli 50 and 40% of the examined samples, with an average counts of 12x10isolates of pathogenic bacteria including 20 isolates each of Escherichia coli 0157:H7, following the biochemical identification tests (Bergey's Manual). Only 56 out of the testes 85 isolates were confirmed as pathogenic species using Hi identification kits and latex test kits. The obtained results indicated that these foods may pose a source of infection to the consumer.
