Isolation and Characterization of Micro-organisms with Industrial Importance From Sisal Bole Rots

Investigation of microorganisms naturally acclimatized to Agave hybrid H 11648 (sisal bole rot) was conducted, with the aim of isolating and characterizing Aspergillus niger strains for industrial use. Microorganism were identified morphologically and then confirmation made by polymerase chain reaction (PCR). Results showed the existence of four major groups, listed in order of abundances as follows; Aspergilli (36.0±0.8) %, Penicillin (28.0±0.1) %, Yeast (15.0±1.6) %and Fusarium (10.0±0.12) %. The main groups of Aspergilli strains were A. nidulans, A. tamari and A. niger in ratios (3:2:2), respectively. Several endo-spore forming non-enteric gram (-) rods and coccid bacteria identified by API20 NE identification systemincluded,Brevundimonas diminuta sp, Shewanella putrefaciens sp, Brevundimonas vesicularis sp and Pasteurella sp. Results showed that sisal bole rot stems hosts a high bio-diversity of microorganism species other than A. niger. Exploitation of the individual strains is recommended. This could eventually produce strains forprecursors of industrially and therapeutically metabolites

Performance of environmental impact assessment (EIA) regime in Tanzania

Tanzania enacted the Environmental Management Act (EMA) in 2004 with Environmental Impact Assessment (EIA) as one of its major tools for protecting environment from the impacts of development projects. According to EMA, all new projects have to undertake EIA before they are commissioned. This paper assesses to what extent this has been achieved. The study involved 5 industries (as cases) which have Environmental Certificates, staff of the National Environment Management Council (NEMC) which is responsible to enforce EMA, Municipal Councils, Wards, Registered Environmental Consulting Firms and NGOs. The assessment focused on institutional strength and weaknesses, awareness of industrial staff and resources allocation for implementation of the Environmental Management Plan (EMP) and Environmental Monitoring Plan (MP). The assessment was done through reviewing Environmental Impact Statement (EIS), site observation, interviews and questionnaires. Study findings show that to a greater extent, EMPs and MPs as presented in EIS are not implemented due to existence of institutional weaknesses, low awareness, poor allocation of resources for EMP implementation and weak enforcement. It was thus concluded that; EIA process apart from identifying potential impacts, it does not go all the way to ensure that they are mitigated. The paper proposes recommendations to remedy the situation
