The present studies delve on the role of enzymes <em>viz</em>., invertase, amylase, glucose oxidase and catalase in nectar-honey transformation during May 2019 to April 2020. Data on enzymatic activity in all the five stages&nbsp; related to honey formation from nectar i.e., floral nectar (fn), honey crop of foragers (hf), honey crop of house bees (hh), unsealed honey cells (uh) and sealed honey cells (sh) was evaluated. Invertase in fn and sh cells was found minimum of 0.00 ml and maximum of 42.40 ml, respectively. Similarly, amylase in the fn was least (0.00 ml) and highest in sh (16.01 ml) and catalase was observed to be 0.001 ml in floral nector and highest in sealed honey cells i.e., 16.01 ml and 4.96 ml,respectively. Accordingly, glucose oxidase in fn and sh cells was minimum of 0.00 ml and maximum of 6.68 ml respectively. Correspondingly, catalase in the fn was least (0.00 ml) and highest in sh (4.96 ml).&nbsp; The analysis of variance of invertase and amylase was significant at 1 % level (p&lt;0.01), whereas glucose oxidase and catalase Were statistically non-significant at 1 % level (p&lt;0.01). Results have confirmed that the sources of all enzymes are instigated from hypopharyngeal, post-cerebral, thoracic, labial and mandibular glands of foragers and house bees which are accountable for honey formation. Further, each enzyme is substrates specific which are discussed in ensuing paper.</p> M. V.

And to determine the occurrence of some contaminated bacteria. 20 samples of Najil fish (<em>P. Pessuliferus</em>) were collected from Port Sudan fish market (in sterile plastic bags) and pre chilled with ice in thermostatic container. All the samples were tested immediately, and instantly froze for four days. Then the studied samples were tested microbiologically and results showed:For fresh fish total bacterial count (TBC) was (5.68×10<sup>5</sup>) CFU/gm, and for frozen samples was (4.38×10<sup>5</sup>) CFU/gm, respectively.The study concluded that, Najil fish (<em>P. Pessuliferus) </em>showed the highest level of contamination between fresh fish. While in frozen fish freeze seem have the higher effect (less number). And the results showed highly significant differences between fresh and frozen fish.The samples were also tested for contaminant bacteria and the result indicated the presence of <em>Staphylococcus</em> and <em>E. coli</em>, while the <em>salmonella</em> and <em>vibrio</em> were absent at each of it.</p> Khansaa Bdr Aldien Osman Ahmed, Samia Hamid Ahmed Hamid, Abdalla N.
